Question

What is HeartBeat? What will happen if Heartbeat stop? ​

Answer 1

Explanation:

Heart beat is the rhythmic contraction and relaxation of the heart which include one systole (contraction phase) and one diastole (relaxation phase) of the heart.

One heart beat = a cardiac cycle. So number of normal heartbeat is 60 to 100 bpm & average is 72 bpm.

Sudden cardiac arrest occurs when the heart suddenly stops beating, which stops oxygen-rich blood from reaching the brain and other organs. A person can die from SCA in minutes if it is not treated right away.
