🎯 Bottom Line Up Front
From a life insurance underwriting perspective, bundle branch block presents a complex risk assessment challenge. The condition itself doesn’t directly cause mortality, but it can be a marker for underlying heart disease that does affect life expectancy. Underwriters must differentiate between benign, isolated bundle branch block and blocks occurring in the context of structural heart disease, coronary artery disease, or cardiomyopathy.
This guide explains how insurance companies evaluate bundle branch block, what documentation maximizes your approval chances, and strategies to secure competitive rates despite this cardiac conduction abnormality.

Understanding Bundle Branch Block and Insurance Risk
Key insight: Life insurance underwriters focus less on the bundle branch block itself and more on what it reveals about underlying cardiac health and structural heart disease.
Bundle branch block is an electrical conduction abnormality visible on ECG, but from an actuarial standpoint, it serves primarily as a potential marker for more significant cardiac conditions. Understanding how insurers interpret this finding helps you position your application optimally.
Why Bundle Branch Block Matters to Underwriters
Insurance companies evaluate bundle branch block through several risk lenses:
- Prognostic significance: Does the block predict future cardiac events like heart attack or heart failure?
- Underlying pathology: Is there structural heart disease, ischemia, or cardiomyopathy causing the block?
- Functional impact: Does the block affect cardiac output or exercise capacity?
- Progressive risk: Is the conduction abnormality stable or worsening over time?
- Sudden death risk: Does the block increase risk of dangerous arrhythmias or complete heart block?
- Associated conditions: What other cardiac or systemic diseases are present?
The Spectrum of Underwriting Risk
Low Risk Profile
- Isolated incomplete RBBB
- Incidental finding on routine ECG
- No symptoms or cardiac history
- Normal echocardiogram and stress test
- No progression over time
- Age under 50 at diagnosis
Expected Outcome: Standard to Preferred rates
Moderate Risk Profile
- Complete RBBB or isolated LBBB
- Diagnosed after age 50
- Mild underlying cardiac condition
- Normal or mildly reduced ejection fraction
- Occasional palpitations but no syncope
- Stable over 2+ years
Expected Outcome: Standard to Table 2 rating
Higher Risk Profile
- LBBB with coronary artery disease
- Reduced ejection fraction (under 50%)
- Heart failure symptoms
- Bifascicular or trifascicular block
- Syncope or near-syncope episodes
- Pacemaker implantation
Expected Outcome: Table 4-8 or postponement
Professional Insight
“The most important conversation we have with bundle branch block clients is understanding the complete cardiac picture. We’ve successfully secured preferred rates for applicants with isolated RBBB and normal cardiac function, while other cases with LBBB and underlying heart disease require more strategic carrier selection and timing. The key is comprehensive cardiac evaluation documentation that either confirms benign isolated block or clearly defines and quantifies any underlying disease.”

RBBB vs. LBBB: Critical Differences in Underwriting
Key insight: Right bundle branch block and left bundle branch block are evaluated completely differently by underwriters due to their distinct prognostic implications.
The distinction between RBBB and LBBB is arguably the most critical factor in how your application will be assessed. These two conditions carry vastly different mortality and morbidity implications.
Right Bundle Branch Block (RBBB)
RBBB involves delayed conduction through the right bundle branch, causing the right ventricle to contract after the left ventricle.
RBBB Underwriting Characteristics
Why RBBB is Generally Favorable:
- Often a benign, incidental finding in otherwise healthy individuals
- Can be congenital or acquired without pathological significance
- Common in athletes and young adults with structurally normal hearts
- Does not independently predict cardiovascular mortality in healthy populations
- May be long-standing and completely stable for decades
RBBB Causes Underwriters Consider:
- Benign/Idiopathic: No identifiable heart disease (best scenario)
- Normal variant: Congenital or developmental variation
- Chronic lung disease: Pulmonary hypertension, COPD
- Atrial septal defect: Congenital heart defect (evaluated separately)
- Right ventricular strain: Pulmonary embolism history
- Myocardial infarction: If involving right coronary artery (increases risk)
Typical RBBB Rate Classifications:
- Isolated RBBB, normal cardiac workup, under age 50: Preferred to Standard Plus
- Isolated RBBB, normal cardiac workup, over age 50: Standard to Standard Plus
- RBBB with mild underlying disease: Standard to Table 2
- RBBB with significant cardiac disease: Evaluated based on the underlying condition
Left Bundle Branch Block (LBBB)
LBBB involves delayed conduction through the left bundle branch, causing dyssynchronous contraction of the left ventricle. This is more concerning from an underwriting perspective.
LBBB Underwriting Characteristics
Why LBBB Receives Greater Scrutiny:
- More frequently associated with underlying structural heart disease
- Often indicates left ventricular dysfunction or cardiomyopathy
- Associated with higher rates of heart failure and sudden cardiac death
- Can independently reduce left ventricular efficiency
- Rarely truly “benign” especially in older adults
LBBB Causes and Their Underwriting Impact:
- Coronary artery disease: Most common cause; significant underwriting concern
- Hypertensive heart disease: Long-standing hypertension causing LV hypertrophy
- Cardiomyopathy: Dilated, hypertrophic, or other forms
- Aortic valve disease: Stenosis or regurgitation
- Myocarditis: Inflammatory heart disease
- Idiopathic/fibrosis: Age-related conduction system degeneration
Typical LBBB Rate Classifications:
- Isolated LBBB, normal EF, no CAD, under age 40: Standard to Table 2
- Isolated LBBB, normal EF, no CAD, over age 40: Standard to Table 4
- LBBB with CAD, normal EF: Table 2-6 depending on CAD severity
- LBBB with reduced EF (40-50%): Table 4-8
- LBBB with reduced EF (under 40%): Often postponed or declined
Comparative Underwriting Table
| Factor | RBBB | LBBB |
|---|---|---|
| Prevalence in healthy population | Common (1-2%) | Less common (0.5-1%) |
| Benign finding likelihood | High – often isolated | Low – usually pathological |
| Associated heart disease frequency | Low in young adults | High at all ages |
| Mortality impact (isolated) | Minimal to none | Modestly increased |
| Best possible rate (isolated) | Preferred Plus | Standard |
| Typical rate (isolated) | Standard Plus | Standard to Table 2 |
| Underwriting complexity | Low | High |
| Required cardiac workup | Echocardiogram usually sufficient | Echo, stress test, often catheterization |
Incomplete vs. Complete Block
The distinction between incomplete and complete bundle branch block also affects underwriting:
- Incomplete BBB: Partial delay in conduction (QRS duration 100-119 ms). Generally viewed more favorably, especially with RBBB. May receive one table rating better than complete block.
- Complete BBB: Full block of conduction (QRS duration ≥120 ms). Standard underwriting approach applies based on type and underlying disease.
Professional Insight
“We consistently see applicants with isolated RBBB achieve preferred or standard plus rates when their cardiac workup is completely normal. In contrast, even isolated LBBB typically starts at standard rates and goes up from there based on ejection fraction and underlying disease. The key for LBBB applicants is demonstrating that the block is truly isolated with comprehensive cardiac testing, and even then, expectations should be calibrated differently than RBBB cases.”

The Underwriting Process for Cardiac Conduction Disorders
Key insight: Underwriters require comprehensive cardiac evaluation to distinguish benign bundle branch block from blocks associated with life-limiting heart disease.
When you apply for life insurance with bundle branch block, underwriters conduct an extensive review of your cardiac health. Understanding what they’re looking for helps you prepare optimal documentation.
Application Questions About Bundle Branch Block
Life insurance applications include specific questions about cardiac conduction abnormalities:
- Date of bundle branch block diagnosis and how it was discovered
- Type of block (RBBB, LBBB, bifascicular, trifascicular)
- Complete or incomplete block
- Symptoms experienced (chest pain, shortness of breath, palpitations, syncope, dizziness)
- Underlying cardiac diagnoses (coronary artery disease, heart failure, cardiomyopathy, valve disease)
- Cardiac testing performed (ECG, echocardiogram, stress test, cardiac catheterization, MRI)
- Ejection fraction and other cardiac function measurements
- Current cardiac medications
- History of heart attack, angioplasty, stents, or bypass surgery
- Pacemaker or implantable cardioverter-defibrillator (ICD)
- Cardiologist follow-up frequency
Critical Cardiac Tests Underwriters Review
| Diagnostic Test | What Underwriters Look For | Impact on Underwriting |
|---|---|---|
| Electrocardiogram (ECG/EKG) | QRS duration, axis, ST-segment changes, old MI evidence, arrhythmias | Very High – confirms BBB type and identifies other abnormalities |
| Echocardiogram | Ejection fraction, wall motion, valve function, chamber sizes, LV hypertrophy | Very High – most important test for risk stratification |
| Stress Test (Exercise or Pharmacologic) | Ischemia, exercise capacity, blood pressure response, arrhythmias | High – identifies coronary disease and functional capacity |
| Cardiac Catheterization | Coronary artery stenosis, hemodynamics, precise EF measurement | High – definitive assessment if performed |
| Holter Monitor or Event Recorder | Arrhythmias, heart rate variability, pauses, PVCs | Moderate – identifies rhythm complications |
| Cardiac MRI | Myocardial scar, infiltrative disease, precise structure and function | Moderate to High – highly detailed information when available |
| Nuclear Stress Test | Myocardial perfusion, ischemia, viability | High – functional assessment of blood flow |
Ejection Fraction: The Most Critical Number
For both RBBB and especially LBBB, ejection fraction (EF) is the single most important metric in determining your rate classification:
Normal EF (≥55%)
Underwriting Perspective:
- Indicates preserved heart function
- Suggests BBB is not causing significant dysfunction
- RBBB: Preferred to Standard Plus possible
- LBBB: Standard to Table 2 typical
Mildly Reduced EF (45-54%)
Underwriting Perspective:
- Mild ventricular dysfunction present
- Requires careful underlying cause evaluation
- RBBB: Standard to Table 2
- LBBB: Table 2-6 depending on cause
Moderately/Severely Reduced EF (<45%)
Underwriting Perspective:
- Significant heart failure present
- High mortality risk
- RBBB: Table 4-8 or postponement
- LBBB: Often postponed or declined
- May qualify after CRT-D if improved
Medical Records Underwriters Request
Expect underwriters to request comprehensive records from multiple sources:
- Cardiologist notes: Complete consultation history including initial workup and ongoing management
- All cardiac test results: ECG, echo, stress test, cath reports with actual images/data
- Primary care records: Documentation of when BBB was first noted and any progression
- Emergency room visits: Any chest pain, syncope, or cardiac-related ER visits
- Hospital records: Admissions for cardiac causes, procedures, surgeries
- Electrophysiology studies: If performed to assess conduction system comprehensively
- Device clinic notes: If pacemaker or ICD implanted
⚠️ Underwriting Red Flags
Certain findings significantly complicate approval or increase premiums:
- New-onset BBB: Bundle branch block that wasn’t present on prior ECGs, especially if recent, suggests acute cardiac event
- Symptomatic BBB: Syncope, presyncope, or severe dyspnea attributable to the conduction disorder
- Progressive BBB: Evolution from incomplete to complete, or RBBB to bifascicular block
- Bifascicular/Trifascicular block: Multiple fascicle involvement increases risk of complete heart block
- Low ejection fraction: EF under 50% dramatically worsens risk profile
- Coronary artery disease: Especially with LBBB, indicates high-risk substrate
- Heart failure symptoms: Dyspnea on exertion, orthopnea, edema with BBB
Underlying Conditions and Their Impact
Key insight: The cause of bundle branch block is often more important than the block itself in determining insurability and premium costs.
Bundle branch block rarely exists in isolation. The underlying cardiac or systemic conditions that caused or are associated with the block significantly influence underwriting decisions.
Coronary Artery Disease (CAD)
The combination of bundle branch block and CAD presents substantial underwriting challenges:
⚠️ CAD + Bundle Branch Block Underwriting
LBBB + CAD: This is a particularly concerning combination as LBBB can mask ECG evidence of ischemia and acute MI.
- Underwriters carefully review extent of CAD (number of vessels, stenosis severity)
- Treatment type matters: medical management vs. stents vs. bypass surgery
- Time since last cardiac event critical (typically need 12+ months stability)
- Ejection fraction becomes paramount – must be ≥50% for consideration
- Typical ratings: Table 4-8 minimum, often higher depending on specifics
RBBB + CAD: Less problematic than LBBB + CAD but still concerning.
- If RBBB preceded CAD diagnosis and remains stable: evaluated primarily on CAD severity
- If RBBB developed after MI: suggests significant right coronary or extensive anterior MI
- Typical ratings: Table 2-6 depending on CAD extent and treatment
Cardiomyopathy
Bundle branch block with cardiomyopathy indicates structural heart disease with significant mortality implications:
- Dilated cardiomyopathy: LBBB very common; underwriting depends on ejection fraction, symptoms, and stability. EF ≥45% may qualify for Table 6-10, EF <40% usually postponed.
- Hypertrophic cardiomyopathy: BBB less common but concerning when present. Evaluated based on obstruction, symptoms, family history. Table 4-8 typical.
- Ischemic cardiomyopathy: CAD with resultant LV dysfunction and BBB. Very challenging to insure. Table 8-10 or postponement common.
- Non-compaction cardiomyopathy: Rare but associated with BBB and poor prognosis. Often uninsurable or Table 10+.
Valvular Heart Disease
Valve disease, particularly aortic valve disease, can cause or coexist with bundle branch block:
- Aortic stenosis + LBBB: Calcific disease causing both valve narrowing and conduction system fibrosis. Severity of stenosis determines insurability. Moderate to severe typically Table 6-10.
- Aortic regurgitation + LBBB: Chronic volume overload may lead to LV dilation and LBBB. Evaluated based on LV size and function.
- Post-valve replacement + BBB: BBB common after aortic valve replacement. Insurability depends on valve type, post-op function, time since surgery. Typically Table 2-6 after 12+ months recovery.
Hypertension
Long-standing hypertension is a common cause of bundle branch block, particularly LBBB:
Hypertensive Heart Disease with BBB
Underwriting Considerations:
- Duration and severity of hypertension reviewed
- Current blood pressure control critical – must be <140/90 consistently
- Evidence of target organ damage assessed (LV hypertrophy, renal function, retinopathy)
- LBBB with controlled HTN, normal EF, no LVH: Standard to Table 2
- LBBB with uncontrolled HTN or significant LVH: Table 4-6
- RBBB with HTN: Usually standard rates unless significant LVH present
Pulmonary Conditions (RBBB)
RBBB can result from chronic lung disease and pulmonary hypertension:
- COPD/Emphysema: Chronic lung disease causes right ventricular strain and RBBB. Evaluated primarily on pulmonary function. RBBB incidental to COPD severity.
- Pulmonary embolism history: Acute PE can cause new RBBB. If RBBB resolved post-PE: minimal impact. If RBBB persists: suggests RV dysfunction, Table 2-4.
- Pulmonary hypertension: Elevated PA pressures cause RV strain. Primary pulmonary HTN very concerning (Table 8-10 or decline). Secondary pulmonary HTN evaluated on underlying cause.
Congenital Heart Disease
Some forms of congenital heart disease are associated with bundle branch block:
- Atrial septal defect (ASD): RBBB extremely common with ASD. If ASD repaired successfully: RBBB has minimal additional impact. Unrepaired ASD evaluated separately.
- Ventricular septal defect (VSD): Can cause RBBB or bifascicular block. Post-repair cases with normal function and isolated BBB: Standard to Table 2.
- Tetralogy of Fallot (post-repair): RBBB nearly universal after repair. Insurability depends on residual lesions, RV function, arrhythmias. Typically Table 4-8.
Essential Cardiac Documentation
Key insight: Comprehensive cardiac evaluation documentation that clearly defines the extent of disease (or confirms absence of disease) is critical for optimal rate classification.
The difference between standard rates and significant table ratings often comes down to documentation quality. Thorough, well-organized cardiac records that definitively answer underwriters’ questions accelerate approval and improve outcomes.
Required Documentation Checklist
Core Cardiac Records
- Complete ECG collection: Current ECG plus any prior ECGs showing when BBB first appeared and whether it has progressed
- Echocardiogram report (within 12 months): Must include ejection fraction, chamber dimensions, valve function, wall motion assessment, diastolic function
- Cardiologist consultation notes: Initial evaluation and all follow-up visits for past 2-3 years
- Stress test results: Exercise or pharmacologic stress test with interpretation (within 12-24 months preferred)
- Cardiac catheterization report: If performed, complete report with angiogram findings and hemodynamics
- Primary care physician records: Documentation of when BBB was first noted and cardiovascular risk factor management
- Hospital records: Any cardiac-related admissions, emergency visits, or procedures
Supplemental Documentation for Optimal Outcomes
- Serial ECGs demonstrating stability: Multiple ECGs over time showing BBB pattern unchanged
- Holter monitor or event recorder results: If performed to evaluate symptoms or arrhythmias
- Cardiac MRI report: If performed, provides excellent structural and functional information
- Nuclear perfusion study: Additional ischemia assessment if done
- Electrophysiology study: If performed to assess conduction system comprehensively
- Current medication list: All cardiac medications with doses and indications
- Physician statement letter: Summary from cardiologist addressing prognosis and functional status
Optimal Documentation Timeline
📋 When BBB First Discovered
- Initial ECG showing bundle branch block
- Prior ECGs (if available) showing absence of BBB to establish timing
- Documentation of circumstances (routine screening vs. symptomatic evaluation)
- Baseline cardiac risk factor assessment
Initial Cardiac Workup (within 1-3 months of discovery):
- Comprehensive history and physical by cardiologist
- Echocardiogram to assess structure and function
- Stress test to evaluate for ischemia and functional capacity
- Additional testing based on findings (catheterization if ischemia detected, etc.)
Ongoing Monitoring Period (6-24 months):
- Periodic cardiologist follow-up (frequency depends on findings)
- Repeat echocardiogram if initial showed any abnormality
- Serial ECGs documenting stability of conduction pattern
- Treatment of any underlying conditions identified
Optimal Application Timing (12-24 months post-diagnosis):
- All testing completed with clear documentation of findings
- If underlying disease present, demonstrated stability with treatment
- Most recent echocardiogram within 12 months showing stable or improved function
- Clear documentation that BBB pattern is stable (not progressive)
✓ Documentation Best Practices
- Obtain complete records: Don’t just get summary letters; obtain actual test reports with measurements and images
- Ensure currency: Echocardiogram and stress test should be within 12-24 months of application
- Address any gaps: If there are monitoring gaps, complete catch-up testing before applying
- Get physician context: A letter from your cardiologist explaining findings and prognosis carries significant weight
- Organize chronologically: Present a clear timeline from discovery through workup to current stable state
- Highlight favorable findings: If you have normal EF, negative stress test, or isolated BBB, make these prominent
⚠️ Documentation Problems That Delay or Worsen Outcomes
- Incomplete workup: BBB without echocardiogram or stress test leaves critical questions unanswered
- Outdated testing: Echo or stress test more than 2-3 years old may require repeat before approval
- Missing baseline: Unable to determine if BBB is new or long-standing
- Progressive changes: Serial ECGs showing worsening conduction delay or development of additional blocks
- Unexplained symptoms: Syncope, chest pain, or dyspnea without adequate evaluation
- Contradictory information: Discrepancies between cardiologist notes and test reports

Professional Insight
“We recently placed two clients with identical LBBB profiles—both age 58, both with normal ejection fraction, both with well-controlled hypertension as the presumed cause. One carrier offered Standard rates while another offered Table 4, representing a premium difference of about 45% for identical coverage. This underscores why multi-carrier submission through a broker with cardiac expertise is essential for BBB cases. We simultaneously submit to 2-3 pre-selected carriers based on their known underwriting philosophies and choose the best offer.”

Frequently Asked Questions
Will my bundle branch block automatically disqualify me from getting life insurance?
Absolutely not. Bundle branch block alone does not disqualify you from life insurance. In fact, isolated right bundle branch block (RBBB) with an otherwise normal cardiac evaluation often has minimal to no impact on your ability to obtain coverage at standard or even preferred rates. The key factors are what type of block you have (RBBB versus LBBB), whether there’s underlying heart disease, and what your cardiac function looks like. Many people with bundle branch block successfully obtain life insurance, though the premiums and rate classifications vary based on the specifics of your cardiac health. The worst-case scenario for most applicants is receiving a table-rated policy with higher premiums rather than outright denial.
Do I need to have a stress test and echocardiogram before applying for life insurance?
While technically not required before applying, having these tests completed significantly strengthens your application and can dramatically improve your rate classification. Most insurance companies will require an echocardiogram and stress test as part of their underwriting process if you haven’t had them recently. If you apply without these tests, one of two things happens: either the insurance company postpones your application until you complete the testing, or they make a conservative underwriting decision based on limited information, likely resulting in higher premiums. It’s far more strategic to complete comprehensive cardiac testing with your cardiologist before applying so you can present the most complete and favorable picture possible. Underwriters view thorough self-initiated evaluation as a positive indicator of health consciousness and medical compliance.
Is left bundle branch block worse than right bundle branch block for life insurance purposes?
Yes, significantly worse from an underwriting perspective. LBBB is viewed much more seriously than RBBB because it’s more commonly associated with underlying structural heart disease and carries independent prognostic implications for heart failure and mortality. Isolated RBBB in a healthy individual can often qualify for preferred or standard plus rates, while even isolated LBBB typically starts at standard rates and goes to table ratings from there. The reason for this difference is medical: LBBB more frequently indicates problems with the left ventricle (the heart’s main pumping chamber), while RBBB can be a normal variant or benign finding in many people. If you have LBBB, expect more intensive underwriting scrutiny, more required testing, and generally higher premiums than someone with RBBB, all else being equal.
What if my bundle branch block was discovered years ago and I haven’t had any problems since?
This is actually an excellent scenario for life insurance purposes. Long-standing, stable bundle branch block with no cardiac events or symptoms demonstrates that your condition is benign and not progressing. Underwriters look very favorably on extended periods of stability. The key is having documentation of this stability—serial ECGs over the years showing the same BBB pattern without worsening, periodic cardiac evaluations showing maintained function, and absence of any cardiac hospitalizations or events. If you have RBBB that’s been stable for 10 years with normal echocardiograms and no symptoms, many carriers will essentially disregard it entirely and offer you their best rates. Even with LBBB, long-term stability with preserved ejection fraction and no complications can result in standard or minimally rated policies. Make sure to gather all your historical cardiac records to document this favorable track record.
Can I get life insurance if I have bundle branch block and have had a heart attack?
Yes, but it will be more challenging and expensive. The combination of bundle branch block and prior myocardial infarction indicates significant cardiac disease, but it’s not an automatic disqualification. The critical factors underwriters evaluate include: time since the heart attack (typically need at least 12 months, preferably 24+ months), current ejection fraction (must be at least 40-45% to be insurable, preferably 50%+), extent of coronary artery disease and treatment received (stents, bypass surgery, or medical management), absence of heart failure symptoms, and stability since the event with no recurrent ischemia. If you’ve had a heart attack followed by complete revascularization, your ejection fraction is now normal, and you’ve been stable for two years, you might qualify for Standard with Table 4-6 ratings. However, if your EF is reduced below 40% or you’ve had multiple cardiac events, you may face postponement or very high table ratings. Working with a broker experienced in cardiac cases is essential for these complex situations.
Will my premiums go up if my bundle branch block gets worse over time?
No—a common misconception about life insurance. Your premium is locked in at the rate determined when your policy is issued based on your health at that time. Future changes in your health, including progression of your bundle branch block or development of new cardiac problems, cannot increase your existing policy premiums. This is true for both term and permanent life insurance policies. The only exceptions are if you selected a term policy and try to renew it at the end of the term period (renewal rates are based on current age, not health, but are generally quite expensive), or if you apply for additional new coverage in the future (which would be underwritten based on your health at that time). This makes applying when your condition is stable particularly advantageous—you lock in rates even if your cardiac health deteriorates later. However, if your bundle branch block is already progressing (incomplete evolving to complete, or RBBB developing into bifascicular block), underwriters will factor this progression into their initial risk assessment and pricing.
Should I mention my bundle branch block if it was discovered incidentally and my doctor said not to worry about it?
Yes, you absolutely must disclose it. Life insurance applications specifically ask about cardiac conditions and ECG abnormalities, and bundle branch block qualifies. Failing to disclose any diagnosed medical condition, even one your doctor considers benign, constitutes material misrepresentation and can result in claim denial or policy rescission. Insurance companies will obtain all your medical records during underwriting and will discover the bundle branch block anyway—it will be in your ECGs, cardiologist notes, or primary care records. Here’s the important perspective: “not worrying about it” from a medical standpoint translates to very favorable underwriting outcomes. If your doctor isn’t concerned and your cardiac workup is normal, underwriters will likely view it the same way and offer you excellent rates. Attempting to hide it only creates problems without providing any benefit, as insurers will find it in your records. Always disclose fully and let your favorable workup speak for itself in the underwriting process.
What happens if I need a pacemaker because of my bundle branch block?
Pacemaker implantation significantly changes the underwriting picture, but doesn’t make you uninsurable. The question becomes why you needed the pacemaker. If your bundle branch block progressed to complete heart block with symptoms like syncope, and a pacemaker was placed prophylactically, underwriters will evaluate the underlying cause of the progressive conduction disease, your ejection fraction, and any other cardiac pathology. Typically, pacemaker for isolated conduction system disease (no structural heart disease) might result in Standard with Table 4-8, depending on specifics. If you required a biventricular pacemaker (CRT) or defibrillator (ICD) because of heart failure with LBBB, the underlying heart failure becomes the primary underwriting concern, often resulting in Table 6-10 or postponement depending on your ejection fraction and functional status. The timing also matters—wait at least 6-12 months after pacemaker implantation before applying to demonstrate device function and stability. Some carriers specialize in pacemaker cases and may offer more competitive rates than others, making broker guidance particularly valuable.
