Life Insurance With AFib: A 2026 South Dakota Guide

Often, yes. A diagnosis of atrial fibrillation, AFib for short, does not automatically shut the door on life insurance, and it rarely means what people assume it means on an application. What actually drives the outcome, according to two national carriers’ own published underwriting guides, is the pattern of your AFib, how it’s managed, your most recent testing, and what else is in your file, not the diagnosis code by itself. This guide walks through how carriers in 2025 and 2026 actually underwrite atrial fibrillation, using real underwriting documents and federal health data, so you can find out where you likely stand instead of assuming the answer is no.

Why “I have AFib, so I assume no” is the wrong starting point

Here’s the pain point in the words we actually hear: My doctor said atrial fibrillation, I looked it up, saw the word “stroke” attached to it, and decided applying for life insurance wasn’t worth the rejection. That reaction is understandable. It’s also not what the carriers’ own underwriting rules say will happen, and it keeps people from ever finding out what they’d actually qualify for.

Atrial fibrillation (AFib) is an irregular and often rapid heart rhythm that starts in the heart’s upper chambers, the atria. It’s the most common type of arrhythmia, a general term for any abnormal heartbeat, irregular in rhythm, too fast, or too slow. AFib shows up in a few patterns: paroxysmal, meaning episodes that come and go on their own, usually lasting minutes to days; persistent, meaning episodes that last longer than seven days or require treatment to stop; and chronic (sometimes called permanent), meaning the irregular rhythm is ongoing and the decision has been made not to try to restore a normal rhythm. The pattern you have is one of the first things an underwriter will want to understand, because it changes the picture considerably.

Underwriting is the process a life insurance company uses to evaluate an applicant’s risk and decide whether to offer coverage, at what price, and in which risk class, also called a rate class, a tier like Preferred Plus, Preferred, Standard Plus, or Standard that sets your premium relative to the carrier’s base rate. A table rating is a priced step above Standard, used for elevated but not disqualifying risk; each step adds a set percentage to the premium, set by the individual carrier. An Attending Physician Statement (APS) is a formal request for your medical records from your doctor or cardiologist, used whenever an underwriter needs more detail than the application provides, and it is required in essentially every arrhythmia case. A contestability period is the window, two years under South Dakota law, during which an insurer can investigate and potentially deny a claim over a material misstatement on the application.

None of this is hidden information. Life insurance carriers publish underwriting field guides for their own agents, laying out in table form what best-case and worst-case outcomes look like for dozens of conditions, AFib included. We pulled the current guides from two national carriers, Pacific Life Insurance Company and the Banner Life family of companies (Banner Life Insurance Company and William Penn Life Insurance Company of New York), to show what they actually say, in plain terms, with no guesswork filling the gaps.

How common is atrial fibrillation, really?

Before getting into the underwriting mechanics, it helps to see the scale of what’s being underwritten, because a lot of the fear behind this pain point comes from treating AFib as rare or unusual. It isn’t.

Sources: National Heart, Lung, and Blood Institute, "Atrial Fibrillation" (last updated Nov. 30, 2022); CDC, "Atrial Fibrillation," citing Miyasaka et al., Circulation (2006) and Colilla et al., American Journal of Cardiology (2013), and citing Tsao et al., "2022 Heart Disease and Stroke Statistics," American Heart Association, Circulation; CMS Office of Minority Health, Data Snapshot No. 16, "Health Disparities in the Medicare Population: Atrial Fibrillation" (Aug. 2016), Chronic Condition Data Warehouse, 2014 data; America's Health Rankings analysis of CDC Behavioral Risk Factor Surveillance System data, 2024. Accessed October 2026.

Put plainly: AFib is already common enough that the National Heart, Lung, and Blood Institute puts the current U.S. count over 2 million, and the CDC’s own projection, built on two separate epidemiological studies, expects that to reach 12.1 million by 2050 as the population ages. Among people already on Medicare, where AFib becomes far more common with age, roughly 1 in 12 had a diagnosed case in 2014, per the CMS data below, rising higher among men than women. A condition at that scale isn’t an edge case sitting in a drawer somewhere in an underwriting manual. It’s common enough that carriers underwrite it routinely.

Stroke risk is the other number worth sitting with. AFib lets blood pool in the heart’s upper chambers instead of moving through efficiently, which raises the odds of a clot forming and traveling to the brain. The CDC, citing the American Heart Association’s 2022 statistical update, puts the increased risk of ischemic stroke associated with AFib at roughly fivefold, after accounting for standard stroke risk factors. That single number is a large part of why every carrier guide we reviewed requires medical records before making a decision, rather than relying on the application alone.

What underwriters actually look at, in their own published guides

This is the mechanism behind the pain point: people picture underwriting as a single box to check next to “arrhythmia.” That isn’t how either guide we reviewed actually works.

Pacific Life’s Underwriting Guide (PLF4249-01, dated November 2025) groups “Arrhythmia/Palpitations (including Atrial Fibrillation, Ventricular Tachycardia, etc.)” as its own line item. It requires an Attending Physician Statement for all cases, and states directly: “Preferred classes may be available if well controlled or recovered,” with the outcome otherwise “depending on severity and presence of other conditions.” That’s a meaningfully open door, not a rating floor. The same guide treats a separate but related condition, heart valve problems, more narrowly: mild mitral valve prolapse with no other heart conditions can also reach Preferred classes, while valve surgery within the last six months is a decline.

Banner Life’s Field Guide for Life Insurance Underwriting (March 2026) doesn’t break out atrial fibrillation as its own line, which is a real difference between the two guides worth knowing about before you assume every carrier documents conditions the same way. What Banner Life’s guide does list, among its declines-and-postpones triggers, is an “Automatic implantable cardioverter-defibrillator,” the device sometimes implanted to manage dangerous heart rhythms. It also includes “Heart (Cardiac) Disease” generally among the conditions that keep an applicant out of its top, Preferred Plus non-medical best class, requiring individual consideration instead. In other words: Banner Life’s published guide tells you less about AFib specifically, and more about the device and general-category thresholds that would apply around it.

Sources: Pacific Life Insurance Company, Underwriting Guide: Confidence for Generations (PLF4249-01), November 2025; Banner Life family of companies (Banner Life Insurance Company and William Penn Life Insurance Company of New York), Field Guide for Life Insurance Underwriting, March 2026. Both guides state individual underwriting decisions depend on the full case and may differ from these examples. Every carrier sets its own guidelines; these two are shown as examples, not the full market.

The real takeaway from putting these side by side isn’t that one carrier is “better” for AFib. It’s that the two guides document the same condition at completely different levels of detail, which means the carrier you apply to can change how your case gets read before an underwriter ever opens your file. That’s exactly the kind of difference an independent comparison is built to catch.

Two worked, hypothetical examples

Take a hypothetical case: a 46-year-old Rapid City resident was diagnosed with paroxysmal AFib 18 months ago. She’s had two brief episodes in the past year, takes a low-dose beta blocker daily, and had a normal echocardiogram at a cardiology follow-up six months ago. She doesn’t smoke and has no other cardiac history.

Under Pacific Life’s published guide, this case lines up closely with the language “well controlled or recovered,” which keeps Preferred classes on the table rather than assuming a rated Standard outcome from the start. An Attending Physician Statement would still be required, as it is for every arrhythmia case, but the specifics here, infrequent episodes, consistent medication, a clean recent test, work in her favor rather than against her. Under Banner Life’s guide, the same case would likely be evaluated under its general cardiac-disease category, which calls for individual consideration rather than an automatic class; nothing in the published guide treats a well-managed paroxysmal case as disqualifying.

Now take a different hypothetical: a 68-year-old Sioux Falls resident has chronic, persistent AFib, takes a daily blood thinner, and also has high blood pressure managed with medication. Under Pacific Life’s guide, the outcome explicitly “depends on severity and presence of other conditions,” language that signals a more involved underwriting review, not an automatic decline. Banner Life’s defibrillator-specific decline trigger wouldn’t apply unless a device is actually implanted; absent that, this case also falls under its general cardiac-disease individual-consideration category. Both examples are built to show how the mechanics work, not a benefit estimate or approval for any real applicant. Every case is evaluated on its own facts and its own test results, at whichever carrier it’s submitted to.

Compare both of those to the version of this story that keeps people from ever applying: I was told I have AFib, so I assume I’m stuck with the worst possible outcome, or no coverage at all. Based on what these two carriers actually publish, that assumption looks wrong for a well-managed paroxysmal case, and incomplete, not automatically bleak, even for a more complicated chronic case with other conditions in the mix.

What it costs to guess wrong

The real cost here isn’t a specific premium figure; no honest source can quote you one without underwriting your actual file. It’s what happens when the assumption of “I’ll be declined” goes unchecked, at a scale that’s easy to underestimate given that more than 2 million U.S. adults already carry this diagnosis, per the National Heart, Lung, and Blood Institute. Two outcomes tend to follow, and both are avoidable:

1. Going without coverage entirely, because applying feels pointless. If something happens to that person, the mortgage, the income replacement, the final expenses, none of it gets covered, not because they were actually uninsurable, but because they never found out.
2. Applying with only one carrier, usually whichever company came up first in a search, and treating that single answer as the final word on “am I insurable,” when a different carrier’s guidelines, as the comparison table above shows, document the same condition very differently.

Both trace back to the same root problem: treating an assumption about AFib as a fact instead of checking it against what carriers actually publish. If you’d rather have someone local walk through your specific diagnosis and compare carrier options directly, that’s a conversation worth having before you decide coverage isn’t available to you. Compare My Options.

How to work through this yourself before you apply

Here’s the method, laid out step by step, no gatekeeping:

1. Write down your AFib pattern. Paroxysmal, persistent, or chronic, the date of diagnosis, episode frequency over the past year, and whether it’s associated with any other diagnosis like high blood pressure, sleep apnea, or a thyroid condition. Underwriters ask for exactly this level of detail, so having it ready before you apply speeds up the process.
2. List your current management. Medications and dosages (beta blockers, blood thinners, antiarrhythmics), any procedure performed (cardioversion, ablation), and whether a pacemaker or defibrillator is involved. A device changes the picture, as Banner Life’s guide shows with its specific decline-or-postpone trigger for implanted defibrillators.
3. Pull your most recent cardiology results. An echocardiogram, stress test, or Holter monitor report from the last six to twelve months gives an underwriter something concrete to evaluate, rather than relying on the diagnosis alone.
4. Understand what the published guides actually reward. Based on the two guides above, a well-controlled, infrequent, paroxysmal pattern with no other cardiac findings is the profile most likely to keep Preferred classes on the table. A chronic pattern with other conditions, or an implanted device, is more likely to need individual underwriting, not an automatic decline.
5. Answer every application question completely and honestly. South Dakota policies carry a two-year contestability period under SDCL 58-15-10, during which an insurer can investigate a claim and deny it for a material misstatement. Leaving something out to improve your odds up front creates real risk for your beneficiaries later.
6. Compare more than one carrier before drawing a conclusion. The side-by-side table above shows one carrier documents AFib by name while another folds it into a general cardiac category. If one company’s guide reads more cautiously than you expected, that isn’t necessarily the final answer across the market.

How we help

We’re an independent agency, which means we aren’t tied to one carrier’s risk appetite or its documentation style. When AFib is part of someone’s picture, that independence is exactly the point: instead of taking one company’s guidelines as the final word, we can look at how different carriers actually treat your specific pattern, medications, and test results, and compare the real options side by side. We start with your specifics, the diagnosis, the episodes, the follow-up care, not a guess, and work from there. If you have a health condition you’ve assumed disqualifies you, it’s worth asking; independent agencies see how different carriers treat the same file. Compare My Options.

What you get

An actual underwriting answer instead of an assumption you never checked. A comparison across carriers instead of one company’s guidelines standing in for “what’s possible.” And, if coverage makes sense once you have real numbers in front of you, a policy sized to your actual situation rather than whatever felt safest to guess at.

Frequently asked questions

Can you get life insurance if you have atrial fibrillation?

Often, yes. Pacific Life’s current underwriting guide groups atrial fibrillation under “Arrhythmia/Palpitations” and states that “Preferred classes may be available if well controlled or recovered,” with the outcome otherwise depending on severity and other conditions in the file. An Attending Physician Statement, a request for your medical records, is required for every case, but that’s a standard step, not a sign the application is in trouble. AFib is also common enough that carriers underwrite it constantly: more than 2 million U.S. adults are estimated to have it today, and the Centers for Disease Control and Prevention projects that figure will reach 12.1 million by 2050.

Does paroxysmal AFib get treated differently than chronic AFib?

The pattern matters to an underwriter, even though the published guides we reviewed don’t break out paroxysmal versus chronic as separate line items. Pacific Life’s guide ties its best outcome, access to Preferred classes, to being “well controlled or recovered,” language that fits an applicant whose episodes are infrequent and managed, better than one with ongoing, persistent AFib plus other cardiac findings. In practice, the fewer episodes, the more stable the medication, and the cleaner the follow-up testing, the stronger the case for a better rate class.

What is a table rating, and would AFib put me in one?

A table rating is a priced step above a carrier’s Standard rate class, used when combined risk factors are elevated but not high enough to decline the application. It isn’t a decline. Whether AFib alone results in a table rating depends on the carrier and the specifics of the case; Pacific Life’s guide explicitly keeps the door open to a Preferred class for well-controlled AFib, while a case with a recent episode, an implanted defibrillator, or other cardiac history is more likely to land in a rated class or need individual underwriting.

Does having a pacemaker or defibrillator for AFib automatically disqualify you?

Not automatically, but it is treated as a flag worth checking before you apply. Banner Life’s March 2026 field guide lists an automatic implantable cardioverter-defibrillator among its decline-or-postpone triggers, which means it’s a case to run past underwriting rather than assume the worst about. Pacific Life’s guide requires an Attending Physician Statement for every arrhythmia case regardless of device, and evaluates the outcome based on severity and the rest of the file.

How common is atrial fibrillation, really?

Common enough that it’s one of the most frequent cardiac conditions carriers underwrite. The National Heart, Lung, and Blood Institute estimates AFib affects more than 2 million U.S. adults as of its most recent update. The CDC projects that number will grow to 12.1 million by 2050 as the population ages. Among Medicare fee-for-service beneficiaries, 8.0% had a diagnosed case in 2014, according to a CMS Office of Minority Health data snapshot, rising to 10.5% among men and 8.4% among women age 65 and older.

Why does AFib raise stroke risk, and does that affect underwriting?

AFib allows blood to pool in the heart’s upper chambers, which raises the chance of a clot forming and traveling to the brain. The CDC, citing the American Heart Association’s 2022 statistical update, puts the increased risk of ischemic stroke associated with AFib at roughly fivefold after accounting for standard stroke risk factors. Underwriters weigh stroke risk indirectly, through the severity of the AFib itself, any history of stroke or clotting events, and the medications used to manage it, such as blood thinners, rather than applying a flat stroke-risk surcharge.

Will being declined by one carrier because of AFib follow me everywhere?

No, and South Dakota law doesn’t require identical thresholds across carriers. SDCL 58-33-26 prohibits an insurer from unfairly discriminating between insureds with genuinely similar risk characteristics, but each company still sets its own underwriting guidelines. Because those guidelines differ, as the Pacific Life and Banner Life comparison in this guide shows, a cautious answer from one carrier reflects that carrier’s own risk appetite for your file, not a verdict on your insurability industry-wide.

Does an AFib diagnosis ever stop mattering for a policy I already own?

For a policy already in force, yes, in a specific legal sense. SDCL 58-15-10 requires South Dakota life insurance policies to become incontestable, except for fraud or nonpayment of premium, once the policy has been in force for two years from its issue date. After that two-year mark, the insurer generally can’t rescind the policy over an application misstatement discovered later. That protection covers coverage you already hold; a new application is underwritten fresh, on its own facts, at whichever carrier you apply to.

The pattern and the paperwork decide this, not the diagnosis

Most people who assume AFib closes the door on life insurance have never actually checked, because the fear of a “no” feels worse than not asking. What the two carriers’ own published guides show is more specific, and less bleak, than that fear: the pattern of your AFib, how it’s managed, your recent test results, and anything else in your file, not the three letters on the diagnosis by themselves. You can write down your own specifics this week, the pattern, the medications, the last echocardiogram, and see how they line up against the guidelines above. That comparison is worth more than another year of guessing.
