Sudden Cardiac Arrest (SCA) is one of the leading causes of death around the globe. Every 40 seconds, a person suffers from Cardiac arrest in the USA, CDC says. Most of the deaths due to cardiac arrest can be prevented if we detect the early signs of a cardiac arrest.

Irregular heart rate and atrial fibrillation can lead to a cardiac arrest or stroke if not treated at the earliest. Fortunately, today some smartwatches and devices come with an ECG sensor that can detect the early warning signs of a cardiac arrest, such as an irregular heartbeat and atrial fibrillation. 

These advanced ECG smartwatches can take ECG or EKG readings within 30 seconds and alert you in case of atrial fibrillation. On top of that, you can share your ECG or EKG report with your doctor as a PDF file for a look.  

In addition to ECG, smartwatches can measure other critical vital signs such as heart rate, blood pressure, blood oxygen level, skin temperature, and much more.  

In this article, I have compiled a list of the best ECG Smartwatches in 2021 approved by the Food and Drug Administration (FDA). This means that the ECG tracing smartwatches listed here are more accurate than the other cheap smartwatches in the market.  

According to a study, FDA Approved ECG Smartwatches can facilitate the health promotion and early detection of cardiac arrest by detecting AF.  

Let us have a quick look into what ECG is and how an EKG Smartwatch works. If you are in a hurry, you can directly jump to our list of handpicked ECG wearables here

The purpose of this article is to help you choose the most reliable ECG smartwatch out there in the market. We have done hours of research and homework to create this list of the best smartwatch and devices with ECG. And we hope that this will help you choose the right smartwatch. 

What is ECG/EKG(Electrocardiogram)?


As I said earlier, ECG or Electrocardiogram is a diagnostic procedure to detect any cardiac disease, including a heart attack.  

The heart starts to beat when an electrical impulse is produced in the SA node at the atria, the heart’s upper chamber. This electrical energy is then transmitted to lower compartments of the heart, the ventricles. Each time the heart beats, a minimal amount of electrical impulses are sent to the skin. An ECG machine tracks this and analyzes this electrical activity for any cardiac abnormalities. Changes in this electrical activity or ECG can be a serious sign of a cardiac issue.  

In hospitals, a 12-lead ECG machine is used to take an ECG. It can give the doctor a lot of information about your heart health. This includes, 

  • Irregular heart rate  
  • Heart block 
  • Atrial fibrillation 
  • Ventricular fibrillation 
  • Heart attack 

But recording ECG at home was not accessible until the introduction of modern wireless wearable ECG devices. Even though a smartwatch cannot recognize a heart attack, it can detect and alert abnormal heart rhythms (cardiac arrhythmias). This helps you to get medical attention immediately before any further complication happens.  

You must seek immediate medical attention if the machine alerts you with atrial fibrillation (AFib) on your ECG. 

What is an Atrial Fibrillation?

 According to heart.org, atrial fibrillation is an irregular heartbeat that can lead to stroke, blood clots, or even heart failure if not treated at the earliest. CDC estimates that more than 12.1 million people (about twice the population of Arizona) in the United States may suffer from atrial fibrillation by 2030.  

Age, high blood pressure, coronary artery diseases, lung diseases, etc., can lead to atrial fibrillation. By detecting the signs and symptoms at the earliest, we can prevent the progression and complication of the disease.  

How does ECG work in a Smartwatch?

ECG Smartwatch

An ECG smartwatch can detect only atrial fibrillation and irregular heart rate only. Like a clinical-grade ECG Machine, it cannot give you a deep insight into your heart health or cardiac diseases. But it allows you to take an ECG or EKG instantly from your wrist and detect an AF, which can lead to a severe health condition or even a cardiac arrest if not treated.  

An ECG Smartwatch comes with PPG sensors that sense the electrical pulses, which leads to a heartbeat. Then the ECG app in the smartwatch analyzes the data for any irregular heartbeat or atrial fibrillation.  

Even though it does not replace any medical equipment, it helps you identify any variation in their heart rhythm. Early identification of these issues saves people’s lives. 

A smartwatch ECG accuracy study suggests that “The ECG feature also shows promise in AF detection and management and may enable users to take a more active role in their health care.”  

ECG Smartwatch Accuracy 

If you are serious about buying a smartwatch that accurately tracks ECG, you should go for a smartwatch approved by the Food and Drug Administration (FDA). An FDA-approved ECG smartwatch means that it is clinically validated for its accuracy. As you may know, getting FDA approval for a device is not an easy task as they test every device thoroughly for its accuracy and performance. 

On top of that, an ECG Smartwatch allows you to take multiple ECGs conveniently from your wrist. This helps your doctor to have a closer look at it when you visit your doctor. This is extremely helpful for a doctor because many symptoms may not have appeared when you visit your doctor, thus ignored, and later it can progress to a severe health problem.  

The AHA (American Heart Association) agrees that smartwatches with ECG can help doctors monitor patients’ heart health.  

Advantages and Disadvantages of ECG Smartwatch

  • Easy to use and convenient.
  • Detects Atrial Fibrillation
  • It does not have cables or wires like traditional ECG Machines
  • FDA Approved smartwatches are more reliable
  • Call Emergency SOS automatically in case of Emergency

  • Only take 30 seconds to take an ECG
  • Fall detection feature
  • It can not be used as medical-grade equipment or does not replace any medical advice
  • It does not detect a heart attack
  • Detects irregular heart rhythm only during ECG
  • Expensive
  • May give wrong alerts on individuals with a Pace Maker

Apple Watch Series 7: Best ECG Smartwatch

Apple Watch Series 7

Apple Watch Series 7 is the latest smartwatch in the list of best ECG smartwatches in 2021. It comes with an FDA Approved electrocardiogram (ECG) sensor and App that can produce an ECG report in 30 seconds.

Once the ECG or EKG is taken, the ECG app assesses the rhythm for any high or low heart rate or atrial fibrillation.

After ECG, an Apple watch will give you any of the following results.

  • Sinus Rythm: An ECG report with sinus rhythm means that the ECG is normal. But in case of chest pain or any other associated symptoms, you must seek medical help immediately. 
  • Atrial fibrillation:  Atrial fibrillation in the ECG report means that the heart rhythm is not normal. It could be an early sign of a cardiac arrest or stroke. This is a severe medical condition and needs immediate medical attention, even if you do not have symptoms of chest pain or chest discomfort. 
  • High or low heart rate: An ECG reading can also detect the heart rate. The ECG tracking feature in an Apple watch works only if your heart rate is between 50-120 beats/minute.
  • Inconclusive: Some time an Apple watch can not classify your heart rate because of multiple reasons. The factors that lead to inconclusive ECG recording are a pacemaker’s presence, not wearing your watch correctly on the wrist, etc. 

Not sure about your ECG report? No worries! Just share your ECG readings with your doctor to seek expert opinions.
