Assuming an average resting heart rate of 70 BPM, for one day alone, the heart will have beaten a little over 100,800 times. Multiply by 365 days, that's approximately 36.8 million beats every year.

A person with an average resting heart rate of 70 BPM, for example, would generate 100,800 heartbeats in one day. In a year, that would add up to approximately 36.8 million beats.
