Frequently Asked Questions
Can an ECG app on a smartwatch check for atrial fibrillation and other heart rhythm abnormalities?
Yes! While an FDA-approved ECG watch is no substitute for a consultation with your doctor, it can help you uncover an irregular heart rhythm and provide the impetus to get checked out. The best ECG smartwatch detects atrial fibrillation and any other abnormalities that could be a sign of blood clots, high blood pressure, sinus rhythm issues, or other problems. And when the ECG recording is part of a comprehensive ECG app that’s easy to read and understand, you can assess the findings of the ECG monitors for yourself and take proper action when needed.
How does an FDA-approved ECG smartwatch work to give you an ECG reading?
Advanced ECG smartwatches complete electrical circuits throughout a wearer’s body to provide an accurate electrocardiogram reading. Wearable ECG devices use two different contact points to provide a comprehensive ECG reading — the point where the watch case touches against your wrists and the points where your opposite hand makes contact with it. With the information these contact points provide, your ECG smartwatch can detect blood flow problems, body temperature changes, and both heart rate spikes and falls.
