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 FDA. 

Smartwatches have sensors that are able to trace the change of 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 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.

  1. Ensure the exact fitting of your ECG smartwatch around the wrist. It should not be too tight nor too loose. 
  2. 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.
  3. 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.
  4. Never take measurements after consuming alcohol and smoking cigarettes. Because these things alter the natural heart rate.
