How slow can a human heart beat?

Answer 1

60-80 beats per minute is about normal for most adults. Faster rate with exercise etc. Children and especially infants hearts beat more rapidly 120-130 not uncommon. When the heart is beating faster that this it is working too hard. The faster it beats the less adequate the circulation. The heart pumps the blood back through the entire body. If it is pumping too fast the body isn't getting good oxygen supply. A heart can beat up to about 300 beats a min but that is way too fast and this is an emergency situation where the heart is beating so fast it is just quivering and not really pumping.

Answer 2

Trained athletes tend to have slow resting heart rates, and resting bradycardia in athletes should not be considered abnormal if the individual has no symptoms associated with it. For example Miguel Indurain, a Spanish cyclist and five time Tour de France winner, had a resting heart rate of 29 beats per minute, one of the lowest ever recorded in a healthy human.

Answer 3

a human heart while being active beats 70 times a minute.

Another answer:

There is really no way to answer this. The human heart may beat at about any speed when a person is active. At rest, many average people beat at 60-75 beats a minute. But their hearts might beat at 120 and above when they are physically action. For the most athletic, their hearts may beat as low as 40-50 bpm, even when active.

Answer 4

about 250 beats per minute depending on the persons physical health and all, it could be higher or lower

Answer 5

It depends on the person and how hard that person is exercising.

My resting heartbeat is 52 beats per minute but the average is 50-80.

Answer 6

60-100 beats/min for adults
