The heart beats normally around 35-40 000 000 times a year in normal conditions. (70 beat/minute) If you then also calculate (for a normal active person) 200 hours of workout â¦ during a year whit raising of the heart beat up to 180 times a minute you can easily pass 50 million heart beats a year.The heart has a capability of beating 70 millions times in one year.he heart beats about 100,000 times a day, on average.   Generally, the heart beats around 70 times per minutes, or just over 4,000 times per hour. (70 x 60 = 4,200) In a f â¦ ull day, that is about 100,000 beats.
A reasonable estimate for the number of heartbeats in a lifetime is about three billion. Hence, in a day (that is, 1, 440 minutes), on an average, the adult heart beats 103, 680 times and a child's hearts beats between 129, 600 and 172, 800 times.nswers.
