Quick Answer
An average human heart beats roughly 2.5 to 3 billion times over a lifetime of about 80 years.
The Full Story
At an average of around 70 beats per minute, the heart beats about 100,000 times a day and roughly 36 to 37 million times a year. Over 80 years that adds up to about 3 billion beats, though the exact total depends on resting heart rate, fitness and activity. With each beat, an adult heart pumps around 70 millilitres of blood at rest. That is about 7,000 litres a day, enough to fill a large tanker truck in a few days. Regular exercise tends to lower resting heart rate, meaning the heart does the same work with fewer beats.
Key Facts
1.The heart beats about 100,000 times a day.
2.It pumps roughly 7,000 litres of blood daily.
3.Well-trained endurance athletes may have resting rates around 40 to 60 bpm.
