What AFib is
Atrial fibrillation is the most common arrhythmia — the upper chambers of the heart quiver instead of beating normally. It is also called atrial fibrillation in full, which is why this page targets both wordings: “AFib” and “atrial fibrillation” are the same condition. The CDC projects that nearly 12 million Americans will have AFib by 2030. For life insurance, the condition matters because it raises the risk of stroke and heart failure, and because the risk depends on the details — which is where underwriting begins.
How underwriters look at it
Underwriters evaluate AFib on its type, cause, severity, treatment and overall cardiovascular health. Paroxysmal AFib — episodes that come and go and resolve on their own — is generally viewed more favourably than persistent or permanent AFib, where the heart stays in an irregular rhythm and needs intervention to correct it. AFib with no underlying heart disease is a different case from AFib caused by mitral valve disease or cardiomyopathy, which carries higher rates. Underwriters also look at stroke risk, including the scoring systems that estimate it, and at stability: a rhythm that has been stable for at least six to twelve months reads very differently from a recent diagnosis.
Treatment counts as evidence, not just as medicine. Rate control, anticoagulants (blood thinners), cardioversion, and ablation are all part of the picture — and so is whether the applicant follows the physician's advice and has regular echocardiograms. An applicant who does not follow advice or skips cardiac follow-up will find it much harder to get a better rate.
What rate class to expect
No rate class is promised for any applicant here, but the range impaired-risk brokers report is consistent. Mild, well-controlled cases — occasional episodes or stable AFib with no complications — often qualify for Standard or Standard Plus rates, the same classes many people without heart conditions receive. Moderate cases, such as AFib requiring blood thinners, a history of cardioversion, or mild symptoms, usually receive a table rating — commonly described as Table B to Table D, or a 25% to 75% addition to the standard premium. More complex cases, with multiple cardioversions, ablations or AFib alongside other heart conditions, may receive higher table ratings or require a specialised carrier. A few exceptional cases — intermittent AFib with excellent cardiac workups — are reported at Preferred, though Preferred Plus is unlikely.
A recent diagnosis is sometimes postponed for 6 to 12 months until underwriters can see how treatment is working. That is a delay, not a decline, and it is the reason to apply when the record shows stability rather than at the moment of diagnosis.
What to prepare
Have the record in the order an underwriter reads it: the type of AFib and the date of diagnosis, how often episodes happen and how long they last, the treatment and whether it is working, the most recent ECG and echocardiogram results, any other heart condition, and blood pressure and cholesterol with their control status. A letter from the cardiologist confirming well-controlled AFib with no complications can help an underwriter see past the diagnosis word to the record behind it — the same principle as the diabetes guide on this site. Disclose the condition exactly as the application asks it: a material omission risks the claim itself under contestability.
If the first answer is a rating or a decline
A rating is not a rejection: it is a higher premium for the same benefit, and its size varies enormously by carrier for the same applicant — one broker's case records show the same applicant rated Table 2 at one carrier, Standard at another, and declined at a third. That variation is why carrier selection matters more for AFib than for most conditions, and why a second and third opinion are worth the effort. Even if you start with a higher rating, many carriers will reconsider the rate class after a year or two of stable health.
A decline from one carrier is not a verdict on insurability. Simplified-issue policies (health questions, no exam) and, as a last resort, guaranteed-issue policies (no health questions, higher price per dollar, usually capped benefits and graded early benefits) remain — but work down that ladder in order, fully underwritten first, simplified next, guaranteed last, because each step down costs more per dollar.
Worked example
Consider two ILLUSTRATIVE applicants. The first has paroxysmal AFib, diagnosed two years ago, with a normal echocardiogram, no underlying heart disease, and a stable rhythm on rate-control medication. The second has chronic AFib with severe underlying heart disease, several cardioversions, and a recent hospital stay. An underwriter would view the first application very differently from the second — not because one diagnosis word is “better” in the abstract, but because type, cause, stability and the rest of the heart all point in different directions. These are ILLUSTRATIVE contrasts to explain underwriting logic; they predict no real applicant's rate class, and no premium figure is asserted for either person.
Illustrative example only — not a fact about any real policy.
