Apple Allows Users to Monitor Heart Rhythm & Take ECG

Apple Watch Series 4 helps users in the US take an electrocardiogram (ECG) directly from the risk, capturing heart rhythm in a moment when they experience symptoms like a rapid or skipped heart beat and providing clinical data to physicians. As reported in the India Times, using the optical heart sensor in Apple Watch Series 1 or later, the irregular rhythm notification feature will occasionally check the user’s heart rhythm in the background for signs of an irregular heart rhythm that appears to be Fib and alerts the user with a notification if an irregular rhythm is detected on five rhythm checks over a minimum of 65 minutes.

“The role that technology plays in allowing patients to capture meaningful data about what’s happening with their heart, right when it’s happening, like functionality on-demand ECG, could be significant in new clinical care models and shared decision making between people and their healthcare providers,” said Nancy Brown, CEO of the American Heart Association.

The ECG app’s ability to accurately classify an ECG recording into AFib and sinus rhythm was validated in a clinical trial of around 600 participants.
