Living with Atrial Fibrillation
Your Apple Watch's rhythm features stay Apple's and your cardiologist's job. Sam takes care of the rest: resting heart rate, sleep, and activity, compared to your own personal baseline - context for your care.
Your data
Your wearable already captures them. Sam reads them from Apple Health and shows you how they shift against your personal baseline.
Sam reads the data your wearable already writes to Apple Health and compares it to your personal baseline - understandable, not a wall of numbers.
Heart rate and heart rate variability vary enormously from person to person - even more so with atrial fibrillation. That's why Sam compares your numbers with your own recent weeks, not with population averages.
Research discusses lack of sleep, alcohol, and stress as possible triggers for episodes - which of these apply to you is something to work out with your doctor. Sam shows you sleep, activity, and resting heart rate in a weekly overview, so you can get a realistic read on your own habits.
The monthly PDF report summarizes your resting heart rate, sleep, and activity trends. Instead of relying on memory, you can show exactly what the past few weeks actually looked like.
Sam is a wellness companion, not a medical device. The app does not diagnose, treat, cure, or prevent any illness and does not replace medical advice. Consult a qualified healthcare professional for medical decisions.
Sam translates your numbers into clear answers and a report you can take with you.
Instead of interpreting charts, you ask questions - Sam answers from your own numbers. For example:
The monthly PDF report sums up your weeks objectively - for appointments, applications, or simply your own record.

Further reading: what wearable data can show about everyday life with Atrial Fibrillation - and where its limits are.
The Apple Heart Study puts real numbers on how accurate Apple Watch rhythm detection actually is. What the irregular rhythm notifications and ECG app can actually do - and where they fall short.
A guide to understanding Apple Watch irregular rhythm notifications and ECG for AFib, and how Sam provides context around daily heart patterns - all without replacing medical care.
Alcohol, sleep apnea, and stress are potential triggers for atrial fibrillation. Here's what current ESC guidelines recommend and how wearable data can help you track patterns at home.
A wearable can't detect heart rhythm like an ECG. Here's what resting heart rate and HRV can show if you have atrial fibrillation - and where wearables hit their limits.
No. Irregular rhythm notifications and the ECG app are separate, regulated features of the Apple Watch. Sam doesn't make rhythm diagnoses - it shows trends in resting heart rate, sleep, and activity compared to your baseline.
That's best discussed with your cardiologist. Many people with AFib keep an eye on resting heart rate, sleep, and exertion - and those are exactly the signals Sam presents in an easy-to-read way, without any manual logging.
No. Sam is not a medical device and doesn't replace ECGs or checkup appointments. The monthly report can, however, help you prepare for those appointments with concrete everyday data.
That depends on your individual situation and is a decision for your cardiologist. The current ESC guideline specifically names physical inactivity as one of the risk factors for atrial fibrillation, so staying active generally makes sense - but the intensity and type of exercise that's right for you is something to decide together with your care team. Sam can show you how your activity develops compared to your own baseline along the way.
A summarized overview is far more useful than a handful of individual snapshots: once a month, Sam bundles your resting heart rate, sleep, and activity trends into a PDF report you can bring straight to your appointment. It's also worth jotting down your own observations - symptoms or notable events - by hand, so your cardiologist gets as complete a picture as possible.
The most helpful thing is a clear-eyed look at everyday habits: helping them get enough sleep, going easy on alcohol together, and calling emergency services immediately - not waiting it out - if symptoms like chest pain, severe shortness of breath, or fainting show up. Sam can help make habits like sleep and activity visible for the person affected, but it doesn't replace medical advice.
