Confidence votes 5.0K. Average heartbeat which is just an average number is 72 beats per minute. 72beats*60mins*24hrs*365.25days=37,869,120. Remember people don't have the same heartbeat rate and no one has the same heartbeat rate all year or every minute.
How quickly your heart beats depends a little on what youâre doing and the specifics of each personâs individual body! The average adultâs heart beats about 70 times every minute. Of course, the number of beats per minute will speed up for certain circumstances (such as exercise or nervousness) and will also slow down for other circumstances (such as resting or sleeping). A personâs average number of heart beats will also vary depending on how healthy and fit that person is. Very athletic people usually have much lower heart rates when resting than other people â some athletesâ hearts beat only 40 to 60 times per minute when they are resting!
