Bonus- What is ECG and Blood Pressure?

ECG or Electrocardiogram helps to detect the heartbeat rhythm and electrical activity of the heart. The ECG sensor records time and strength that is taken by an electrical signal to make a heartbeat.

Based on these readings, it checks whether a person is having atrial fibrillation or irregular heartbeat rhythm. Here’s more about what ECG is and its importance on a smartwatch.

Blood Pressure is measured when a heart pumps blood into the large blood vessels of the human circulatory system. Then the blood moves throughout the body that puts pressure on the vessel walls which is said to be the blood pressure level. Here’s more about blood pressure monitoring on smartwatches.

This is how you can enable and use ECG and blood pressure monitor on your Galaxy Watch 4 anywhere in the world. I hope this article helps users in India, the USA, and other countries where ECG and BP features are not yet available. Stay tuned for more such informative content.
