Top Features to Look for in a Heart-monitoring Smartwatch

Here are some characteristics to look for when comparing heart-monitoring smartwatch options. These capabilities benefit athletes, people with chronic health concerns, and anyone who wishes to check their cardiac measurements. None of these characteristics or readings should be used in place of medical treatment or official cardiological examinations.

Heart rate monitoring

The most fundamental feature to look for is heart rate monitoring. Almost all smartwatches and activity trackers contain heart rate monitoring, although some offer more advanced monitoring features such as heart rate variability monitoring, stress tracking, and heart rate alarms. Heart rate alerts can be set to generate an alert if your heart beats outside of its typical range for an extended period based on your normal resting and active heart rates (what is normal varies from person to person).

When paired with activity tracking, heart rate reading can help you determine how hard you work and how many calories you burn throughout an exercise. This is one of the more common applications for wristwatch heart monitoring.

ECG capabilities

Many people are unaware that smartwatches can capture ECGs. Yet, the Apple Watch has had ECG capabilities for several generations, and Samsung and Google have begun offering the feature. ECG is an abbreviation for electrocardiogram (also known as an EKG). It is a test that determines the frequency and strength of electrical signals produced by your heart as it beats and contracts.

This test aims to look for abnormal cardiac activity, such as atrial fibrillation (a form of irregular heart rhythm that happens when the top and lower chambers of the heart are out of sync). 

This is a useful monitoring tool for people with a history of or at risk of an abnormal sinus rhythm. However, because smartwatches do not screen for heart attacks, you should always go to the ER if you suffer unusual chest pain, as any smartwatch does not identify many cardiac events. Those who receive an atrial fibrillation reading should seek proper medical attention since the watch is intended to be a useful monitoring tool rather than a diagnostic test or a replacement for regular hospital ECGs/EKGs.

Fall Detection

Fall detection transforms your smartwatch into a fashionable, high-tech Life Alert gadget. If the watch detects a fall, it will prompt you to call 911 or a specified emergency contact or to report that you are safe. If you do not clear the notification within a certain time, it will send an alert to emergency services or your emergency contact.  

Fall detection is not a heart health feature. However, it may be useful if you or the person you’re shopping for requires a heart-monitoring smartwatch due to a cardiological ailment that can cause falls or fainting.

Health Tracking and Phone Pairing

You’ll want a smartwatch that syncs with your phone or has a compatible mobile app to access data. This allows you to access reports on your heart rate, exercise activities, ECG readings, blood oxygen levels, stress levels, and other metrics that have been recorded. If you have an iPhone, an Apple Watch 8 may be preferable for easier pairing. Similarly, owners of Samsung Galaxy smartphones may benefit more from a Samsung Galaxy Watch 6.
