Everyone's heart rate are not the same, in fact, the heart rate and life expectancy is a relationship, according to the latest study, heart beat faster, the shorter the life.

Many people often naturally or half unconsciously to count his own pulse. Indeed, every pulse beat, represents a valid heart beat, to pump blood to the wrist. Pulse of the law or not, beat frequency, especially when compared with normal incidence, can give clinicians bring many rare first-hand information, is conducive to the doctors' judgment. But have you ever noticed their frequency of the pulse is fast or slow?

In medicine, the normal heartbeat frequency definition per minute for 60 - 100 times.Jia Ke su But in recent years, more and more medical research results indicated that, with increasing heart rate, shorten the life of a health hazard, an increase in cardiovascular morbidity and mortality. Accordingly, can say none exaggeratively, pulse faster and faster, the shorter the life.

The modern concept that, if a person of average pulse recurrent or persistent reaches or exceeds 80 times per minute, though still less than 100 times per minute in the normal range, but also has a fast growing. Of course, an electrocardiogram, a pulse, or excited, after exercise pulse temporarily faster than 80 times per minute were not chronic fast pulse. The most objective to the number of dynamic electrocardiogram ( Holter ) recorded the mean heart rate, which is 24 hours, including daytime and night, quiet and activity rate of mean value, so the value is very meaningful.

Chronic fast pulse, often unnoticed and found, that is still within the normal range, but its harm can be long-term, occult existence. In fact, as early as in 1945, renowned scholar levy will publish an article to point out, the heart beats per minute for 100 times mortality is much higher than the heartbeat slow. 40 years later, the United States of America 's most famous epidemiological investigation, by John studies published a more convincing data, at the age of 35 - 84 year-old crowd, prospective follow-up of 26 years the results show that, with the heartbeat is accelerated, mortality showed a significant upward trend, especially in the male population.

In mammals, the heartbeat is slower, longer life expectancy, such as the rat heart of up to 500 times per minute, life of only 2 years, the turtle heart is only 6 times per minute, life up to 200 years.varicose veins tips Studies have shown, the elderly heart rate each increase 5 times / min, myocardial infarction and sudden death in an 14% increase in the risk of.

Chronic fast pulse is the human sympathetic nerve activation markers and long-term performance, may promote the blood pressure, blood sugar, lipid metabolism and insulin resistance. Thus, chronic fast pulse can use beta blockers or calcium antagonists for treatment, preferably the resting pulse is reduced to about 60 times per minute.

Of course, the pulse is too slow or adverse health. A U curve, namely the pulse of less than 50 beats / min or long term of more than 80 beats / min will cause increased mortality.
