The Heart

How fast and how often does the human heart beat?

The human heart beats 130 times per minute in infants and slows to 90 times per minute in a ten year old. By the time adulthood is reached, the heart slows to an average of 70 times per minute in men and 78 times per minute in women. The heart will beat approximately 40 million times in one year, or about 3 billion times in an average lifetime.
