Atrial fibrillation (also known as AFib or AF) is an arrhythmia (quivering or irregular heartbeat) that can cause blood clots, strokes, and heart failure. When a person has AFib, the usual beating in the top chambers of the heart (the two atria) is irregular, and blood flow from the atria to the lower chambers of the heart isn’t as efficient as it should be (the two ventricles). AFib can manifest itself as a series of transient episodes or as a long-term disease.
So how does this relate Apple? You can take an electrocardiogram (ECG) with the ECG app and an Apple Watch. The ECG app for Apple Watch Series 4, Series 5, or Series 6* can record your heartbeat and rhythm using the electrical heart sensor, and then check the recording for atrial fibrillation (AFib), a type of abnormal rhythm.
