8 Best ECG Smartwatches in 2021: Top Brands Only

“Here is my hand-picked list of the best ECG smartwatches and devices for 2021. Read the complete review to choose the best ECG monitoring devices trusted by many.”

Best ECG Smartwatches

According to the CDC, 6,55,000 Americans die every year due to cardiac diseases, which means that one person dies every 36 seconds due to cardiac diseases in the USA. 

ECG or Electrocardiogram is a life-saving feature added to the latest smartwatches. It can detect irregular heart rate and atrial fibrillation (abnormal rhythm), which can be the initial signs of heart failure, stroke, or other cardiac complications. 

But just having a device like an ECG smartwatch may not help you because accuracy matters a lot here. If you want to have a closer look at your cardiac health (heart health), you must have one of the best ECG smartwatches clinically validated by the authorities like the U.S. Food and Drug Administration.

Today in this article, I have listed the best FDA Approved ECG Smartwatches in 2021. I hope this will helps you to choose the best ECG monitoring smartwatch.

What is Electrocardiogram (ECG or EKG)?


Electrocardiogram, or ECG for short, is a medical test that detects your heart’s electrical impulses. This helps doctors diagnose any cardiac issues you may be experiencing. A 12 lead ECG is often used in hospitals, and it can detect potential problems with your heart rate, rhythm, conduction, and repolarization. 

How does it work?

Our heart pumps blood as a result of electrical activity occurred within the heart. A small amount of this electrical impulse is being sent to the skin as well. An ECG Machine/device can detect, measure, and interpret this electrical activity with the help of electrodes attached to the body.

There will be some variations in the heart rhythm in case of heart disease, and a doctor can easily detect it from the ECG.

Hospitals use advanced ECG machines to take 12-lead ECG, and it can detect severe heart conditions like cardiac arrest, heart failure, etc. A standard EKG machine has ten electrodes. Six electrodes are attached to the chest, and the other four electrodes are attached to each limb to take an Electrocardiogram.

Why should you buy an ECG Smartwatch?

ECG Smartwatches come with advanced PPG sensors to measure and analyze your cardiac activity. Even though it cannot give you as many details as a 12-lead ECG, it can give you some valuable insight into your heart health.  However, it can still detect Atrial Fibrillation and irregular heart rhythms, which could be early signs of cardiac arrest or stroke. 

Advanced ECG smartwatches can take ECG or EKG readings within 30 seconds and alert you in case of atrial fibrillation.

These are the expected ECG results that you can get on a smartwatch. 

Sinus Rhythm: A sinus rhythm means that your heart is working normally.

Atrial Fibrillation: Atrial Fibrillation is an abnormal heart rhythm, and it can lead to a heart attack, blood clots, stroke, etc., if not treated on time. If your ECG watch alerts you with atrial fibrillation, immediately call the emergency service for medical help.

Inconclusive: It means that your smartwatch cannot detect your heart rhythm due to multiple reasons such as elevated or decreased heartbeats, presence of a pacemaker, ICD (Chest Tube), etc.

Accuracy of an ECG Smartwatch

There are many ECG tracking smartwatches available in the market today. But how to choose the right smartwatch? This is a common question asked by many. When you buy an ECG smartwatch, you should always go for a smartwatch approved by the FDA. ECG Smartwatches from Apple, Samsung, and Fitbit are clinically validated by the FDA, and it is accurate in recording your ECG. 

Cardiologists also agree that the ECG smartwatches help them to monitor the heart health of their patients.
