6 Industry’s First FDA-Approved ECG Monitor on Your Wrist

In addition to a revamped and more functionally advanced heart rate monitor, the Apple Watch Series 4, unlike the Series 3 before it, features the addition of an FDA-approved electrocardiogram (ECG) monitor. Functionally, this game-changing new ability allows Apple Watch S4 owners to scan and measure their heart rhythm so as to detect for any underlying or abnormal heart conditions.
