Galaxy Watch 5 adds FDA-approved AFib monitoring and narrows Apple Watch gap

The US Food and Drug Administration (FDA) just gave Samsung the green light on its Irregular Heart Rhythm Notification feature (IHRN) for the Galaxy Watch series.

Recent models, like the Galaxy Watch5, come with heart monitoring tools like on-demand ECG recording (opens in new tab) and HR Alert. What’s unique about IHRN is it specifically looks for signs of atrial fibrillation, or AFib, by utilizing the device’s ECG (electrocardiogram) function and BioActive Sensor. AFib occurs when a person suddenly has a rapid, irregular heartbeat. Samsung claims (opens in new tab) the condition “is widely considered a warning sign for major cardiovascular issues that can increase the risk of stroke”. Some cases can even be “asymptomatic”, leaving people totally unaware of what’s going on with their bodies.
