    Top features to look for in a smartwatch for heart monitoring

    Here are some features to look for when evaluating smartwatch options for heart monitoring. These features can be useful for athletes, those with chronic health conditions or anyone that wants to track their heart metrics. None of these features or readings is a substitute for medical care or formal cardiological tests.

    Heart rate monitoring

    The most basic function to look for is heart rate monitoring. Almost all smartwatches and activity tracker include heart rate monitoring, but some include more advanced monitoring options like heart rate variability monitoring, stress tracking or heart rate alerts. Heart rate alerts can be adjusted based on your own normal resting and active heart rate (what is normal varies from person to person), to provide an alert if your heart is beating outside of it's normal range for a sustained period of time.

    When combined with activity tracking, heart rate reading can help you assess how hard you are working during a workout and how many calories you are burning. This is one of the more popular uses of smartwatch heart monitoring.

    ECG capabilities

    Many people aren't aware that smartwatches can take ECGs, but the Apple Watch has had ECG functionality for several generations and both Samsung and Google have started offering the feature as well. ECG stands for electrocardiogram (also called an EKG). It is a test that measures the frequency and strength of the electrical signals generated by your heart while it is beating and contracting. The purpose of this test is to check for abnormal cardiac activity such as atrial fibrillation (a type of irregular heart rhythm that occurs when the upper chambers of the heart are out of sync with the lower chambers). 

    This is a helpful monitoring tool for those with a history of or who are at risk for irregular sinus rhythm. However, it's worth noting that smartwatches does not check for heart attacks, so you should still always go to the ER if you experience unusual chest pain, as there are many cardiac events that will not be detected by any smartwatch. Those that get a reading of atrial fibrillation should also seek appropriate medical care, as the watch is meant as a helpful monitoring tool and not a diagnostic test or replacement for traditional hospital ECGs/EKGs.

    Fall Detection

    Fall detection turns your smartwatch into a trendy, more high-tech Life Alert device. If the watch detects a fall it will give you the option to call 911 or a designated emergency contact or report that you are alright. If you don't clear the notification within a set period of time it will then automatically send an alert to emergency services or your emergency contact.  

    Fall detection isn't technically a heart health feature. However, if you or the person that you are shopping for need a heart monitoring smartwatch due to a cardiological condition that can lead to falls or fainting, it may help

    Phone pairing and Health Tracking

    You'll want a smartwatch that can either pair with your phone or provides a compatible mobile app to view data. This allows you to view reports on your heart rate, exercise activity, ECG readings, blood oxygen, stress levels and other recorded metrics. If you have an iPhone, you may prefer an Apple Watch 8 for easy pairing. Similarly, Samsung Galaxy smartphone users may get more out of a Samsung Galaxy Watch 6.
