how many times does a healthy human heart beat?

Answer 1

The average human heart beats approximately two billion times in a lifetime.

Answer 2

Healthy Human Heart

Answer 3

Difficult question because of variability. Here is an example: a healthy newborn's heart beats over 120 beats per minute at rest(that's twice a second). A healthy adult athlete's heart may beat closer to 45 beats per minute (because of excellent conditioning). Both are healthy humans, but they are also very different when it comes to how their bodies work.

Answer 4

A normal heart rate is between 60 and 100 beats per minute. An athletic person may have a slightly lower heart rate.

Answer 5

There is no one answer to this question. A lot depends on the age of the person, hereditary factors, health of person, etc. Also, there is a "window range" or perimeter of what is considered normal for each person. Check with your doctor. He can tell you if your heart beat number is normal or not considering all factors mentioned above. You can have several different people, all healthy, all with healthy hearts, and chances are, none of them will have the same "number of heart beats". Consult your physician.

Answer 6

60-100 beats per minute is the average for an adult. However athletes can be alot lower. I have seen some athletes with rates in the 40's and sometimes even lower and be healthy.

Answer 7

Normally a healthy human heart beats 60 to 100 beats per minute.

This is the same as

- 86,400 to 115,200 beats per day

OR

- 31,536,000 to 42,048,000 beats per year

However these figures vary from person to person due to various factors such as age, sex, stature, activity, emotions etc.

How many times does your heart beat per year?

Dear Cecil:

How many heartbeats does the average person have in one year? -- Faustino R., Los Angeles

Dear Faustino:

Your heartbeat, naturally, is by no means constant. The rate can vary from minute to minute, depending on stress and body temperature. In one famous, if rather grisly, experiment, a team of researchers in Utah in 1939 took an electrocardiogram of a man about to be executed by a firing squad. His heartbeat increased from 72 to 180 just before the shots were fired. Afterward, of course, the rate dropped sharply.

A rate of 72 to 80 beats per minute is generally considered normal for a healthy human being at rest. At birth, the rate is in the neighborhood of 130 beats per minute, with the figure decreasing through adolescence and then showing a slight upswing in old age. Women (and this seems to apply to the females of most species) have a faster heartbeat than men. Clams have the slowest heartbeats of all God's creatures, varying from 2 beats per minute for a clam en repos to 20 for a clam in a state of extreme nervous excitement.

Since the solar year consists of 525,948 minutes and 48 seconds, a quick calculation at the rate of 80 BPM gives us a ballpark figure of 42,075,904 beats per year, give or take a couple mill. A reasonable estimate for the number of heartbeats in a lifetime is about three billion.

Answer 9

In a lifetime? I saw a commercial for a heart medication today that said something like 2 billion times?

Answer 10

65 to 85 beats per minute. Pres. Bush's beats about 45 times per minute. Genetic abnormality.
