Brigham and Women's Hospital answeredAt an average rate of 80 times a minute, the heart beats about 115,000 times in one day or 42 million times in a year. During an average lifetime, the human heart will beat more than 3 billion times -- pumping an amount of blood that equals about 1 million barrels. Even when a person is at rest, the heart is continuously hard at work.
Eric Olsen, Fitness, answeredThe heart works tirelessly through a lifetime to pump blood throughout the body, and when it's working properly, it never misses a beat. The typical adult heart will beat about 31 million times in a year, or upward of two billion beats in a lifetime.
