However, before buying your ECG smartwatch it’s crucial to know all the factors that would help you to buy the best ECG smartwatch at your budget price. Let’s have a look..

ECG Report Feature

Among all the features, this is the most important thing you should be looking at on an ECG smartwatch.

In addition to that, always go for the FDA-approved ECG smartwatch. Because they generate data that usually have a decent level of accuracy. 

Try to buy those smartwatches that not only have an ECG report system but also have the option to share the data instantly with your personal doctor. 

Versatile Fitness Features

Undoubtedly the top-notch feature you need to check is that the ECG smartwatch you are planning to buy will work smoothly with your phone. Or you will simply keep biting your own fingers after losing a couple of hundreds of bucks.

Because there are many ECG smartwatches out there in the market that will specifically sync and connect with specific phones. So you gotta be really careful about it.

Some Apple watches work and syncs just with the higher model iPhones. Even some suits with Samsung but not with another Android. Read out the compatible mobile phone of your ECG smartwatch before purchasing it. 

Battery Life

Different models of ECG smartwatches have different levels of battery life. Check the battery rating if it seems good. Go for it. Make sure you are purchasing the one that will easily go for one day without charge. 

It’s really painful to let it charge multiple times a day. However, if you intend to use your ECG smartwatch frequently then no matter which model you buy it will lose a significant amount of charge. 

Fast Wireless Charging

Many ECG smartwatches come with features like wireless chargers and they do charge really fast. Some come with cables too. Try to buy the wireless one as it’s convenient and upgraded tech.

Water Resistance

If you often go for swimming training, live in an area where it mostly rains, or engage in a job where water is unavoidable then buy the ECG smartwatch which has a better-than-average water resistance level. 


Most of the smartwatches are now upgraded enough and provide a minimum comfort level for long-term use. But still, different people find comfort in different materials. Have a look as each model offers unique watch bands

The latest models are not only lightweight but also made with ultra-comfortable wear bands that will increase your comfort level. Plus, don’t forget to ensure that the ECG smartwatch has replacement bands. 


High-end ECG smartwatch keeps the communication options available for their consumer. You as a user must look at texting and calling features in your smartwatch. It reduces the hassle of checking out the phone from a pocket or bag. 

How does ECG work in a smartwatch?

Nowadays, this technology has been embedded into smartwatches which can show instant results of ECG and many of them got their approval from the FDA. 

Smartwatches have sensors that are able to trace the change in your heart rate based on the blood volume passing inside your wrist. 

Apple watches use PPG technology to show you the ECG result using an algorithm. This algorithm will be able to produce a notification if there is a big gap or more frequency in the heart rate. 

The main difference between an ECG at any hospital and the wearable smartwatch is that in hospitals the machine has 12 leads while a smartwatch has a single lead to take the readings of your heart signal.

How do you know if you’re monitoring your HR correctly? 

While measuring your heart rate using the smartwatch, you can do a few things to make sure it’s working properly.

  • Ensure the exact fitting of your ECG smartwatch around the wrist. It should not be too tight nor too loose. 
  • As you sweat, your smartwatch sensor might also get dirty a bit. Keep it clean to ensure there’s no obstruction during the reading of heart rate.
  • If your body temperature is cold or has low blood circulation, it’s ideal to take measurements after a warm-up to get the optimum result.
  • Never take measurements after consuming alcohol and smoking cigarettes. Because these things alter the natural heart rate. 

Advantages and Disadvantages of ECG Smartwatch

Every health technology improves with time. With the upgrade of technology, a lot of errors are reduced. You can see the same thing with the ECG smartwatches. 

In the below part, I will briefly explain the advantages and disadvantages of ECG smartphones. So let’s have a look.
