In 1min heart beats 72times then how many times does the heart contract & relax in one beat ??​

Answer 1

Answer:

The normal range is between 50 and 100 beats per minute. If your resting heart rate is above 100, it's called tachycardia; below 60, and it's called bradycardia. Increasingly, experts pin an ideal resting heart rate at between 50 to 70 beats per minute.
