Understanding AV Block Types and Insurance Impact
Key insight: The specific type and degree of AV block determines everything in insurance evaluation—outcomes range from zero impact to significant table ratings.
AV blocks exist on a spectrum from clinically insignificant electrical delays to life-threatening complete conduction failure. The classification system (first, second, third degree) provides critical prognostic information that directly translates to insurance risk stratification. Understanding these distinctions is essential because an applicant with first-degree AV block may receive preferred rates while someone with third-degree block typically receives table ratings—despite both having “AV block” in their medical records.
✅ Minimal to No Impact
Standard or better rates typical
- First-degree AV block (asymptomatic)
- Second-degree Type 1 (Wenckebach) in young athletes
- Reversible AV block (medication-induced, resolved)
- Transient AV block (Lyme disease, treated)
- No structural heart disease
- Normal heart function
- No symptoms
Expected: Standard or better rates
⚠️ Moderate Consideration
Standard to table ratings
- Second-degree Type 2 (Mobitz II)
- Second-degree with structural heart disease
- Intermittent high-grade AV block
- AV block with mild heart failure
- Post-pacemaker (good function)
- AV block with CAD or cardiomyopathy
- Symptomatic second-degree block
Expected: Standard to table ratings
🔴 Significant Impact
Table ratings typical
- Third-degree (complete) AV block
- AV block with significant heart disease
- Recent pacemaker implantation (under 6 months)
- Pacemaker complications or malfunctions
- AV block with reduced ejection fraction
- Progressive conduction disease
- Multiple cardiac comorbidities
Expected: Standard to table ratings based on severity
Professional Insight
“The term ‘AV block’ in medical records always prompts us to immediately check which type and degree. We recently had two applications come in within days of each other, both noting ‘AV block’ in records. The first was a 55-year-old marathon runner with first-degree AV block—incidental finding on EKG, no symptoms, no heart disease. He received preferred rates. The second was a 62-year-old with third-degree AV block requiring pacemaker implantation, with underlying ischemic cardiomyopathy. He received Table 4. Same general diagnosis category, completely different insurance outcomes because the specific type of block determines the prognosis and therefore the rating.”

First-Degree AV Block
Key insight: First-degree AV block is a minor electrical delay that typically has zero to minimal insurance impact in otherwise healthy individuals.
First-degree AV block is characterized by prolonged conduction through the AV node, manifesting on EKG as a PR interval greater than 200 milliseconds (0.20 seconds). Every atrial impulse still reaches the ventricles—there’s just a delay. This is extremely common, occurring in 1-2% of healthy adults and even more frequently in athletes and the elderly. In the absence of other cardiac disease, first-degree AV block is generally benign and doesn’t progress to higher-degree blocks in most cases.
✓ Favorable First-Degree AV Block Scenarios
Standard or better rates typical:
- Asymptomatic: No palpitations, dizziness, syncope, or exercise intolerance
- Incidental finding: Discovered on routine EKG without clinical suspicion
- No structural heart disease: Normal echocardiogram, no valve disease, normal heart function
- No underlying cause: Not due to medications, ischemia, infiltrative disease, or other cardiac conditions
- Stable PR interval: Not progressively lengthening over time
- Young healthy patient: Athletic or otherwise healthy individual
- No other conduction abnormalities: No bundle branch blocks or other EKG issues
- Normal Holter monitoring: No progression to higher-degree blocks on extended monitoring
Expected outcome: Standard or better rates; first-degree AV block often not even mentioned in underwriting decision
⚠️ First-Degree AV Block Requiring Evaluation
Usually still standard rates after clarification:
- Very prolonged PR: PR interval over 300ms (0.30 seconds) warrants evaluation for progression risk
- Progressive lengthening: PR interval increasing on serial EKGs
- Associated with other disease: First-degree block in context of cardiomyopathy, CAD, or myocarditis
- Medication-induced: Due to beta-blockers, calcium channel blockers, digoxin, or antiarrhythmics
- Post-cardiac surgery: Developed after valve surgery or other cardiac procedures
- Young patient with symptoms: Syncope or presyncope in young person even with first-degree block
Expected outcome: Standard or better rates after documentation; underlying cause evaluated if present
✓ Why First-Degree AV Block Has Minimal Insurance Impact
First-degree AV block is viewed favorably by underwriters for several reasons:
- Extremely common: Present in 1-2% of healthy population, even more in athletes
- Generally benign: Does not cause symptoms in isolation
- No mortality impact: Studies show no increased death risk from first-degree AV block alone
- Usually doesn’t progress: Most cases remain stable without advancing to higher-degree blocks
- No treatment needed: Observation only unless associated with other cardiac disease
- Athletic association: Common in endurance athletes due to high vagal tone—actually a sign of fitness
These factors position first-degree AV block similarly to other benign EKG variants that are noted but not rated in otherwise healthy individuals.
| Clinical Context | Insurance Approach | Expected Rates |
|---|---|---|
| Healthy adult, PR 210-240ms, no symptoms | No underwriting concerns; noted and cleared | Standard or preferred rates |
| Athlete, PR 220-260ms, no symptoms | Athletic heart syndrome; actually favorable | Standard or preferred rates |
| On beta-blocker, PR 240ms, stable | Medication effect; acceptable if clinically appropriate | Standard or better rates |
| PR 320ms, progressively lengthening | Monitor for progression; cardiologist evaluation reviewed | Standard rates typical after evaluation |
| First-degree with CAD or heart failure | Underlying disease rated; first-degree block noted | Based on underlying cardiac disease |
Second-Degree AV Block (Mobitz I & II)
Key insight: Second-degree AV block requires careful subtype classification—Type 1 is usually benign while Type 2 indicates more serious conduction disease.
Second-degree AV block occurs when some, but not all, atrial impulses are blocked from reaching the ventricles. This is divided into two types with very different clinical significance and insurance implications. Type 1 (Mobitz I, also called Wenckebach) shows progressive PR interval lengthening until a beat is dropped, then the cycle repeats. Type 2 (Mobitz II) shows sudden dropped beats without progressive PR prolongation, indicating disease in the His-Purkinje system below the AV node and carrying much higher risk of progression to complete heart block.
✅ Type 1 (Mobitz I / Wenckebach)
Usually benign, standard or better rates
- Location: Block typically at AV node level (above His bundle)
- Common in: Athletes, vagal tone, sleep (normal phenomenon)
- Prognosis: Generally excellent; rarely progresses
- Treatment: Usually none needed unless symptomatic
- Symptoms: Typically asymptomatic
- Insurance: Standard or better rates in most cases
🔴 Type 2 (Mobitz II)
More serious, requires evaluation
- Location: Block in His-Purkinje system (below AV node)
- Common in: Structural heart disease, post-infarction
- Prognosis: Risk of progression to complete block
- Treatment: Often requires pacemaker
- Symptoms: May cause dizziness, syncope
- Insurance: Standard to table ratings based on management
| Feature | Type 1 (Mobitz I) | Type 2 (Mobitz II) |
|---|---|---|
| PR interval pattern | Progressive lengthening before dropped beat | Constant PR, sudden dropped beat |
| Block location | AV node (proximal) | His-Purkinje (distal) |
| Progression risk | Low risk of progression | High risk of complete heart block |
| Pacemaker need | Rarely needed (only if symptomatic) | Often indicated (especially if symptomatic) |
| Associated disease | Can occur in healthy hearts | Usually indicates structural disease |
| Typical insurance outcome | Standard or better rates | Standard to table ratings |
⚠️ The Critical Type 1 vs. Type 2 Distinction
Ensuring medical records clearly specify which type of second-degree AV block is present makes an enormous difference in underwriting:
- Type 1 (Wenckebach): Often seen during sleep in healthy people, common in athletes, usually requires no treatment, and has excellent prognosis—typically standard or better rates
- Type 2 (Mobitz II): Indicates His-Purkinje disease, carries risk of sudden progression to complete block, often requires pacemaker, and suggests underlying structural disease—typically standard to table ratings
Medical records that simply state “second-degree AV block” without specifying type create underwriting uncertainty that’s resolved conservatively (higher ratings). Clear documentation of “Mobitz Type 1” versus “Mobitz Type 2” is essential.
Professional Insight
“The distinction between Mobitz Type 1 and Type 2 second-degree AV block can mean the difference between preferred rates and Table 3. We had a client whose records noted ‘second-degree AV block’ without specifying type. Initial underwriter assumed Type 2 and proposed Table 3. We requested clarification from the cardiologist who confirmed it was Type 1 (Wenckebach) occurring only during sleep in an otherwise healthy marathon runner. With that clarification, the client received standard rates—no rating at all. That single clarification saved over $2,000 annually in premiums. Always ensure the specific type is documented when dealing with second-degree AV block.”

Third-Degree (Complete) AV Block
Key insight: Third-degree AV block is a serious condition requiring pacemaker, but successful pacing allows many patients to achieve standard to moderate table ratings.
Third-degree or complete AV block occurs when no atrial impulses reach the ventricles. The atria and ventricles beat independently, with the ventricles driven by a slow escape rhythm (typically 30-40 beats per minute). This is a life-threatening condition that almost always requires permanent pacemaker implantation. Without pacing, patients are at risk for syncope, cardiac arrest, and sudden death. With successful pacing, however, most patients can lead normal lives, which significantly improves insurance prospects compared to the pre-pacemaker era.
Complete AV Block: Pre-Pacemaker
Immediate concern:
- Life-threatening condition: Risk of cardiac arrest without pacing
- Severely limited cardiac output: Slow ventricular rate inadequate for activity
- Syncope risk: Sudden loss of consciousness from inadequate perfusion
- Emergency indication: Requires urgent pacemaker implantation
- Insurance application: Would be postponed pending pacemaker placement
Action: Pacemaker implantation required before insurance consideration
Complete AV Block: Post-Pacemaker (Optimal Scenario)
Best insurance outcomes after pacemaker:
- 12+ months post-implant: Proven pacemaker function and patient adaptation
- No underlying heart disease: Conduction system issue only (congenital, idiopathic)
- Normal heart function: Ejection fraction 55%+, no heart failure
- Excellent pacemaker function: Interrogation showing appropriate sensing/pacing, good battery life
- No symptoms: Normal exercise tolerance, no syncope or dizziness
- No pacemaker complications: No lead issues, infections, or device problems
- Good overall health: No diabetes, kidney disease, or other significant comorbidities
Expected outcome: Standard to Table 2 ratings possible with this profile
Complete AV Block: With Complicating Factors
Moderate to higher ratings:
- Underlying heart disease: CAD, prior MI, cardiomyopathy causing or coexisting with block
- Reduced ejection fraction: EF under 50%, especially under 40%
- Recent implantation: Less than 6-12 months post-pacemaker
- Pacemaker complications: Lead dislodgement, infection, or other device issues
- Persistent symptoms: Ongoing dizziness, exercise intolerance despite pacing
- Multiple comorbidities: Diabetes, kidney disease, COPD, or other conditions
- Advanced age at onset: Complete block in elderly with multiple risk factors
Expected outcome: Table 2 to Table 4+ depending on severity of complicating factors
✓ Why Paced Complete AV Block Can Achieve Reasonable Rates
Modern pacemaker therapy has dramatically improved outcomes for complete AV block patients:
- Normalizes heart rate: Pacemaker provides physiologic heart rate appropriate for activity level
- Prevents sudden death: Eliminates risk of fatal bradycardia or asystole
- Restores function: Most patients return to normal activities with pacing
- Reliable technology: Modern pacemakers are highly dependable with long battery life (8-12 years)
- Objective monitoring: Pacemaker interrogations provide hard data on device function and heart rhythm
- Good prognosis: When no underlying heart disease present, paced complete block has favorable outlook
These factors allow underwriters to view paced complete AV block more favorably than many other cardiac conditions requiring devices.
Pacemaker Considerations
Key insight: Pacemaker presence is viewed as appropriate treatment rather than negative factor—successful pacing improves insurability compared to unpaced high-degree block.
Pacemakers are implanted for symptomatic bradycardia from AV block, typically for Mobitz Type 2 second-degree or complete third-degree block. The device continuously monitors the heart rhythm and provides pacing impulses when the intrinsic rate falls below programmed limits. Life insurance underwriting of pacemaker patients focuses on the indication for the device, underlying cardiac disease, pacemaker function, and overall cardiac status.
| Pacemaker Factor | What Underwriters Assess | Impact on Rates |
|---|---|---|
| Time Since Implant | Months/years since pacemaker placed | 6-12+ months preferred to demonstrate stable function |
| Indication for Pacing | AV block only vs. multiple indications | Pure AV block better than heart failure/multiple issues |
| Pacemaker Dependency | Percentage of time paced; underlying rhythm present | 100% paced (no escape rhythm) higher risk than occasional pacing |
| Device Type | Single, dual, or biventricular (CRT) pacemaker | CRT devices indicate heart failure; rated accordingly |
| Interrogation Results | Recent device check showing function, battery, leads | Normal function essential; issues worsen ratings |
| Complications | Infections, lead problems, pocket issues | Resolved complications minor impact; ongoing issues significant |
| Symptom Relief | Resolution of syncope, dizziness, exercise intolerance | Complete symptom relief optimal; persistent symptoms concerning |
| Underlying Heart Disease | Isolated conduction disease vs. CAD, cardiomyopathy, etc. | Isolated conduction disease much more favorable |
Professional Insight
“Pacemaker patients often worry the device itself will prevent insurance approval, but that’s not accurate. The pacemaker is appropriate treatment that improves prognosis—underwriters understand this. What matters is why you needed the pacemaker and how well it’s working. We recently placed a 58-year-old with pacemaker for complete AV block (congenital) who was 18 months post-implant with perfect device function, normal heart otherwise, and excellent health—she received Table 2. Another 65-year-old needed pacemaker for AV block but also had significant heart disease with EF of 38%—he received Table 5. The pacemaker itself wasn’t the issue; the underlying cardiac status determined the ratings.”

Underlying Causes and Their Impact
Key insight: The cause of AV block often matters more than the block itself—idiopathic or congenital blocks rate better than those from ischemia or infiltrative disease.
AV block can result from numerous causes, each with different prognoses and insurance implications. When evaluating AV block, underwriters always investigate the etiology because it provides critical information about overall cardiac health and future risk.
| Cause of AV Block | Clinical Significance | Insurance Impact |
|---|---|---|
| Idiopathic/degenerative | Age-related fibrosis of conduction system | Generally favorable; isolated conduction issue |
| Congenital | Born with conduction abnormality | Usually favorable if well-managed; often requires pacing in adulthood |
| Ischemic (CAD/MI) | Block from heart attack damaging conduction system | Rated based on CAD severity; block is complication |
| Medication-induced | Beta-blockers, calcium blockers, digoxin, antiarrhythmics | If reversible with medication change: minimal impact |
| Post-cardiac surgery | Valve surgery, septal myectomy, etc. | Depends on underlying disease and surgical outcome |
| Lyme disease | Infectious cause; usually resolves with treatment | Minimal impact if resolved; treated Lyme disease alone benign |
| Infiltrative disease | Sarcoidosis, amyloidosis affecting heart | Significant impact; these diseases have poor prognosis |
| Cardiomyopathy | Block occurs with dilated or restrictive cardiomyopathy | Rated based on cardiomyopathy severity |
| Myocarditis | Inflammation causing conduction abnormalities | Depends on resolution and residual heart damage |
⚠️ When Underlying Cause Drives the Rating
In many cases, the underlying cardiac disease that caused AV block is rated more heavily than the conduction disorder itself:
- AV block from prior MI: Rated primarily for coronary disease and left ventricular function
- AV block with cardiomyopathy: Rated for heart failure severity and ejection fraction
- AV block from cardiac sarcoidosis: Rated for systemic sarcoidosis with cardiac involvement
- AV block from amyloidosis: Very serious prognosis; high table ratings or declined
Understanding the complete cardiac picture beyond just the AV block diagnosis is essential for accurate risk assessment.
Essential Medical Documentation
Key insight: Precise documentation of AV block type, degree, underlying cause, and pacemaker function (if applicable) prevents underwriting delays and improves outcomes.
📋 Core Documentation Requirements
- EKG reports showing specific type and degree of AV block with measurements (PR interval, etc.)
- Cardiology consultation notes with diagnosis, classification, and treatment plan
- Holter monitor or event recorder results if performed to assess block patterns
- Echocardiogram showing heart structure and function (ejection fraction)
- Stress test results if performed, showing exercise tolerance and heart rate response
- Pacemaker implant operative note if device placed, including indication and device type
- Recent pacemaker interrogation (within 6 months) showing device function, battery, pacing percentages
- Underlying cause documentation including workup to determine etiology of block
- Medication list noting any drugs affecting AV conduction
- Symptom assessment documenting presence or absence of syncope, dizziness, exercise intolerance
✅ Documentation That Strengthens Applications
- EKG report clearly stating “first-degree AV block, PR 220ms”
- Cardiology note: “Mobitz Type 1, benign, no treatment needed”
- Statement: “Asymptomatic, discovered incidentally”
- Echo report: “Normal LV function, EF 60%, no structural disease”

Frequently Asked Questions
Can I get life insurance with AV block?
Yes, most individuals with AV block can obtain life insurance, though outcomes depend heavily on the specific type. First-degree AV block typically has zero to minimal insurance impact, often qualifying for standard or better rates—it’s an incidental finding in many healthy people and athletes. Second-degree Type 1 (Wenckebach) is usually benign and also often qualifies for standard or better rates. Second-degree Type 2 (Mobitz II) and third-degree (complete) AV block are more serious and typically result in standard to table ratings, especially if pacemaker is required. The key factors are the precise type of block, whether you have a pacemaker, underlying cardiac disease, and overall heart function. Even complete AV block with pacemaker can achieve standard to Table 2-3 ratings with good outcomes.
Will first-degree AV block prevent me from getting life insurance?
No, first-degree AV block rarely affects life insurance eligibility or rates at all. It’s an extremely common finding—present in 1-2% of the healthy population and even more frequently in athletes and older adults. As long as you’re asymptomatic, have no structural heart disease, and the block is stable, underwriters typically note it and move on without any rating impact. You can often qualify for preferred rates despite having first-degree AV block if you’re otherwise in excellent health. The block represents a minor electrical delay that doesn’t cause symptoms, doesn’t progress in most cases, and doesn’t affect mortality—making it essentially irrelevant for life insurance purposes in the vast majority of cases.
How does having a pacemaker for AV block affect life insurance rates?
Having a pacemaker for AV block typically results in standard to table ratings depending on several factors. The pacemaker itself is viewed as appropriate treatment that improves prognosis, not as a negative factor. What matters most is why you needed the pacemaker, how well it’s functioning, and whether you have other cardiac disease. If you have a pacemaker for isolated complete AV block (no other heart disease), normal heart function, and excellent pacemaker function documented 12+ months post-implant, you might achieve standard to Table 2 ratings. If the AV block was caused by a heart attack or cardiomyopathy, or if your heart function is reduced, you’ll typically receive Table 2 to Table 4 ratings or higher. The key is comprehensive documentation showing good pacemaker function and overall cardiac status.
What’s the difference between Mobitz Type 1 and Type 2 for insurance purposes?
The difference is substantial for life insurance. Mobitz Type 1 (Wenckebach) is generally benign—it’s common in athletes and healthy people, especially during sleep, and rarely progresses to complete block. Most applicants with Type 1 second-degree AV block qualify for standard or better rates if otherwise healthy. Mobitz Type 2, however, indicates disease in the His-Purkinje system below the AV node, carries significant risk of sudden progression to complete heart block, and usually requires pacemaker implantation. Type 2 typically results in standard to table ratings even with pacemaker, reflecting the more serious underlying conduction system disease. Ensuring your medical records clearly distinguish between these two types is critical—the difference can be several table rating classes, translating to thousands of dollars in annual premium differences.
I have third-degree AV block with a pacemaker. Can I still get affordable coverage?
Yes, affordable coverage is achievable for many people with paced third-degree AV block. While you likely won’t qualify for preferred rates reserved for the healthiest applicants, standard to Table 2-3 ratings are realistic if you have isolated conduction disease (no other heart problems), normal heart function (ejection fraction 50%+), excellent pacemaker function, and have been symptom-free since pacemaker implantation. More typically, applicants with complete AV block receive Table 2-4 ratings. Even with underlying cardiac disease or reduced heart function, coverage is usually obtainable at Table 4-6 ratings. The key is waiting 6-12 months after pacemaker implantation to demonstrate stable device function, maintaining good overall health, and having comprehensive documentation of your cardiac status.
My AV block is from Lyme disease that was treated. Does this affect my rates?
Lyme disease causing temporary AV block that resolved after antibiotic treatment typically has minimal to no insurance impact. Lyme carditis (cardiac involvement in Lyme disease) can cause various degrees of AV block, but this usually resolves completely with appropriate antibiotic therapy. If your AV block was clearly due to Lyme disease, was treated with antibiotics, and has resolved (documented on EKG showing normal conduction), you should expect standard or better rates. Some applicants even qualify for preferred rates if the Lyme disease is completely resolved and no other health issues are present. The key is clear documentation showing the AV block was Lyme-related, appropriate treatment was completed, and current EKGs show resolution of the conduction abnormality.
Does AV block from medications affect life insurance?
Medication-induced AV block is generally viewed favorably if it’s reversible. If you developed AV block while taking medications known to affect AV conduction (beta-blockers, calcium channel blockers, digoxin, certain antiarrhythmics) and the block either resolved when the medication was discontinued or is stable and appropriate given the medication indication, this typically has minimal insurance impact. Underwriters will want to understand why you’re taking the medication (what underlying condition) and evaluate that condition separately. For example, if you have mild first-degree AV block from a beta-blocker you’re taking for hypertension, you’d be rated based on your blood pressure control, not the AV block. If the medication was stopped and the block resolved completely, even better—standard or better rates are typical.
Should I wait to apply after pacemaker implantation for AV block?
Yes, waiting 6-12 months after pacemaker implantation typically results in better rate classifications than applying immediately post-procedure. The waiting period allows you to demonstrate successful pacemaker function with at least 1-2 device interrogations showing appropriate sensing, pacing, and no complications. It also provides time to document complete symptom resolution and return to normal activities. While you can apply earlier if you have urgent coverage needs, rates will likely be 1-2 table classes higher than if you waited. The difference between applying at 3 months versus 12 months post-pacemaker can mean Table 4 versus Table 2—potentially saving hundreds to thousands of dollars annually in premiums. Use the waiting period to ensure all follow-up testing is complete and results are optimal before applying.
