    "Your heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times."

    Heart Beats In A Lifetime

  • 1 decade ago

    For a human, the calculation is like this:

    Interval Beats

    per min 72

    per hour 4,320

    per day 103,680

    per year 37,869,120

    70 yrs 2,650,838,400

    Total in a lifetime of 70 yrs is about 2.5 billion heartbeats.

    As a matter of interest, mice and small birds have about 1000 heartbeats a minute and live for (say) 4 years. Total heartbeats will be getting on for 2.5 billion.

    The blue whale heart beats at about 6 times a minute. How long should it be able to live according to this principle? The answer suggested is over 300 years.

    This all depends on how long that person lives for, but if we take the average person surviving the average age of a human life-span (approximately 80 years), then the average persons heat will be a staggering three billion times! However, some people have what is known as a rapid heartbeat. This is where the heart works overtime and beats faster than it should.

    A rapid heart beat or palpitations as they are sometimes called, are an awareness of your own heartbeat, usually because the heartbeat seems irregular, or unusually rapid, or in some other way "different" to normal. An abnormal heart rhythm is referred to as an arrhythmia.

    Normally you are not aware of your heart beating at all. The heart beats in response to an electrical stimulus - a bit like the way a car engine fires in response to a spark from a spark plug, and palpitations usually stem from a problem in this electrical system that generates the heartbeat. The heart muscle can continue to contract effectively even if the electrical system is "misfiring" from time to time.

    People have described their palpitations in lots of different ways, but there are some common patterns such as, it feels like the heart has stopped (although it hasn't) and the heart feels fluttery in the chest,

    Palpitations may be associated with feelings of anxiety or panic; it is normal to feel the heart thumping when you are terrified of something, but it may be difficult sometimes for people to know which came first, the palpitations or the panic feeling. Unfortunately, since it can take some time before a clear diagnosis is made in a patient complaining of palpitations, people are sometimes told initially that the problem is anxiety.

    Stressful situations cause an increase in the level of stress hormones, such as adrenaline, circulating in the blood, and there are some types of abnormal heart rhythm that can be stimulated by adrenaline excess, or by exercise. It may be possible to diagnose these sorts of palpitations by performing simple tests, such as an exercise test, while monitoring the ECG.

    Some types of abnormal heart rhythm seem to be affected by posture, and you may notice that standing up straight after bending over provokes a rapid heart rate. Often these attacks can be abolished again by lying down. Many people, if not all of us, are more aware of the heartbeat when lying quietly in bed at night. This is partly because our attention is not focussed on other things, but also because the slower heart beat at rest can allow more premature beats to occur.

    Assuming some averages:

    80 beats/minute x 60 minutes/hour x 24 hours a day x 365 days a year x 75 years = 3,153,600,000

    3.15 billion times

    If the average heart beat for a normal person is around 2.5 billion for his lifetime , why would he want to reach that point earlier and faster by running, jogging, or other form of activities ?!!!!

    I have an excel speadsheet that worked it out, for a person who is approximately 76 years old would have had 3 billion heart beats.

    the average non athletic heart beats 2,799,360,000 for 72 years, the athletic heart beats an average of 1,866,240,000 in 72 years. The athletic heart is bigger and needs to beat less to pump more blood.

    70 years / lifetime

    x 365 days / year

    x 24 hours / day

    x 60 minutes / hour

    x 70 beats / minute

    = 2,575,440,000 beats / lifetime

    Roughly two and a half billion.
