Well.
The normal heart is a strong, muscular pump a little larger than a fist. It pumps blood continuously through the circulatory system. Each day the average heart beats 100,000 times and pumps about 2,000 gallons of blood. In a 70-year lifetime, an average human heart beats more than 2.5 billion times.
From the moment it begins beating until the moment it stops, the human heart works continuously.
That is a long time also it never stops :O
