What is ECG on a smartwatch and how accurate is it?
ECG on a smartwatch records your heart's electrical activity and can spot signs of irregular heart rhythm like atrial fibrillation.
ECG stands for electrocardiogram — it's a reading of your heart's electrical activity. Your smartwatch uses sensors to record this activity and checks if your heart rhythm looks normal or irregular. It's a helpful screening tool that can catch problems early, but it's not a medical diagnosis — your doctor still needs to confirm anything serious. Think of it like a heads-up system: it can spot when something seems off, but it isn't a replacement for professional medical care.

Common mistakes to avoid
- Taking a single unusual reading as a diagnosis — ECG is a screening tool, not a diagnosis. One reading doesn't prove you have a problem.
- Ignoring doctor advice because the watch shows normal — smartwatch ECG is helpful but doesn't replace professional medical care
- Checking ECG constantly throughout the day — a few readings per week is plenty for routine monitoring
