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.
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.
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 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
You'll want a smartwatch that can either pair with your 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 or for easy pairing. Similarly, Samsung Galaxy smartphone users may get more out of a Samsung Galaxy Watch 6.

Advances in electrocardiogram (ECG) technology are truly remarkable. Not long ago, if you had worrisome symptoms, you had to either visit your doctor to get an ECG, call 911, or drive to an emergency room. Then came the revolutionary Holter monitor in , which allowed you to take a continuous ECG reading in your own home. For a long time, it could only record continuously for 24 hours, and you needed to get lucky to catch any symptoms during that time. But then, newer monitors, including the more convenient ECG patch monitors, stretched that monitoring interval to a few weeks; however, these require a prescription from your doctor.
Now, you can go out and buy a heart monitor that you wear on your wrist, without a prescription from your doctor. It can automatically monitor your pulse multiple times a day, and to take an ECG, all you have to do is put your finger on the watch&#;s crown. This new heart monitor, known as a smartwatch, would&#;ve been unfathomable to Dr. Holter 50 years ago. I, too, still remember marveling at the quality of the tracing when I took my first Apple Watch ECG only two years ago.
So what can your smartwatch ECG do? And what can it tell you about your heart? Just what are all the features packed into that heart monitor on your wrist? In this post, I&#;ll walk you through these questions and help you understand what your smartwatch is designed to do and importantly, what it is not designed to do.
&#;
For us cardiologists, the ECG is the most common test that we order for patients. It gives us an electrical picture of how the heart is beating. We use the ECG to tell if electrical signals are flowing smoothly, if there is injury to the heart, if the heart is too big, or if there are other medical conditions.
The ECG you get from a smartwatch gives you a limited view of this picture. Instead of the 12 &#;leads,&#; or angles, that you&#;d get from the ECG at your doctor&#;s office, you get one lead: &#;lead I.&#; The good news is that you can still learn a lot about your heart with this single lead. When professional photographers are asked, &#;What is the best camera you can get?,&#; they often respond, &#;The one you have on you when you need it.&#; Similarly, taking a single-lead ECG anytime you wish is invaluable.
Note that the ECG application on the Apple Watch and similar devices were designed for one task: to detect Atrial Fibrillation (AFib). Why? AFib is the most common arrhythmia, affecting over 1% of the US population, and it is associated with an increased risk of stroke, along with other poor outcomes. So, it makes sense to focus a lot of the features on this abnormal heartbeat. The FDA has specifically cleared the Apple Watch ECG for this purpose. In fact, when you take your ECG with this device, the only medical condition that it can tell you about is AFib.
The ability of smartwatches to identify AFib correctly from the ECG is not perfect, but it is very good. There are, however, some limitations to keep in mind. If the heart rate is too fast, which often happens during AFib, the app is unable to classify it as AFib. If there is too much electrical noise, which can happen if you are moving or contracting your arm muscles, then the app cannot interpret the ECG. If the electrical signals are too small, it can also be challenging. Some people, for example, have an irregular heartbeat due to extra heart beats or just normal variation, and if the ECG signal is too small, the watch may get confused. But despite these limitations, the smartwatch ECG usually does this one job of AFib detection very well.
Not only does the ECG app aim to detect if you have AFib, but it also stores the ECG reading, which you can then convert to PDF to send to your health care provider or review yourself. As a cardiologist, I believe the quality of the Apple Watch ECG tracing is usually high enough for me to read and make an interpretation. I&#;ve had several patients identify AFib with their smartwatch, and I&#;ve been able to validate by reviewing their PDF tracings. And although you only get a single lead with the smartwatch ECG, there are many insights beyond AFib that a trained professional can glean from reading that one lead.
Most importantly, with a clean recording, we can learn what the heart rhythm actually is. The heart rhythm describes the way that the heart beats electrically. &#;Normal sinus rhythm&#; is a description of the normal way that the heart beats &#; with organized contraction at the top chambers of the heart (atria), followed by organized contraction at the bottom chambers (ventricles). AFib is just one of many types of abnormal heartbeats that can cause palpitations, fatigue, shortness of breath, or similar symptoms. There are also extra heartbeats or premature beats, fast heartbeats such as supraventricular tachycardia and ventricular tachycardia, slow heartbeats such as heart block, and other abnormal electrical problems. The tricky thing is that many of these abnormalities can come and go quickly. To get a diagnosis, you need to catch them at the moment of your symptoms. If you have an abnormal electrical heartbeat other than AFib, the ECG app won&#;t tell you what it is, but you can send a PDF of your ECG to your health care provider, or to Qaly (on Android or iPhone) for a cardiographic technician&#;s interpretation.
In a few cases, heart attacks, which are problems with blockages in the blood vessels around the heart, can be picked up on the single lead ECG; however, this is not a reliable way to assess whether you might be having this serious condition. Also, a single lead ECG usually does not provide enough information to rule out structural abnormalities of the heart. For these, a full, multi-lead ECG is needed, along with additional heart testing. Likewise, an ECG is not used to tell if you are having a stroke, lung problems, or other serious cardiovascular conditions. This is why we recommend talking to your doctor if you are experiencing any new symptoms, and not relying solely on the smartwatch ECG.
