How many heart beats in a lifetime?
On average, the heart beats between 60 and 100 times per minute, or about 2.5 billion times in a lifetime. Each heartbeat consists of two phases: systole and diastole. Systole is the contraction of the heart muscle, which pumps blood out of the heart. Diastole is the relaxation of the heart muscle, which allows blood to fill the heart.Heart Attack - Related Articles
