ECG Apple Watch App: The Ultimate Guide

How do you use the ECG app on Apple Watch Series 4, 5, and 6? Follow this guide to find out.

 

One of the most significant features of the best Apple Watches is the ECG heart rate monitor that works through the wearable device's Digital Crown. The current and historical ECG data, which is viewable on your iPhone Health app, can be shared with your doctor.

 

Who can access the ECG app and irregular rhythm notification?

The ECG app is available on the Apple Watch Series 4, Series 5, and Series 6 in select countries. The tool is not available on the Apple Watch SE or older models. The irregular rhythm notification feature, which is also limited to select countries, is available for users of the Apple Series 1 and beyond.

What does ECG on Apple Watch do?

The ECG app on the Apple Watch is intended to take an electrocardiogram right from your wrist. In doing so, it can capture heart rhythm and detect problems such as rapid or skipped heartbeats. The app uses electrodes built into the back of the wearable device and Digital Crown. With this, you can take an ECG similar to a single-lead reading.

According to The National Institutes of Health, "single-lead reading devices give only limited information as compared to conventional 12‐lead ECGs. Hence, concerns about their accuracy and reliability need to be examined."

As Apple explains, "The ECG app does not detect a heart attack, blood clots, a stroke or other heart-related conditions including high blood pressure, congestive heart failure, high cholesterol or other forms of arrhythmia."
