What pulse is considered normal in humans?

By how many contractions our heart makesin one minute, you can find out how healthy we are. For example, a frequent heartbeat may indicate that a person has problems with the nervous system and immunity. If the person’s pulse has fallen, this may be a symptom of increased intracranial pressure, hypothermia, or poisoning. Many doctors believe that at rest, the heart of a healthy person makes 60-80 beats per minute. But the results of a study conducted by American scientists showed that all this time, doctors could be seriously mistaken and not notice signs of serious illness in patients.

It was previously believed that the human heart makes 60-80 beats per minute

About the new discovery of scientists from the United States was written inscientific journal PLOS ONE. As part of the scientific work, the researchers studied data on the heart rate of at least 92 thousand people. All of them were united by an average age in the region of 46 years and that they wore a bracelet for a year to track heart rate for a year. As it turned out, the “normal” heart rate in different people may vary. If for one person 60 beats per minute is the norm, for another such a heart rate can be a signal for the development of cardiovascular diseases.

An increased heart rate is called tachycardiaand low bradycardia.

How many beats per minute does a human heart make?

In the course of studying the data of 92 thousand participantsThe study found that the heart rate in humans ranges between 40 and 109 beats per minute. Scientists were greatly surprised by such a wide range of heart rate of people. In the course of further work, it turned out that the heart of men makes from 50 to 80 beats per minute, and for women - from 53 to 82 beats per minute.

According to scientists, heart rate mayfactors such as age, body weight, and bad habits like excessive alcohol and smoking. At some points, people experience sharp changes in the frequency of strokes, and this is especially true for women. According to scientists, this is due to hormonal changes that occur during each month. Changes in heart rate were also observed in different seasons of the year. For example, in January, people's hearts beat faster than in June.

Each person can have their own “normal” heart rate

In the end, scientists concluded that suchconcepts like a “normal heartbeat” may not exist at all. It turns out that when the attending physician sees that the patient’s heart rate is 70 beats per minute and calls him healthy, he can be very mistaken. As mentioned above, for some people 60-80 beats per minute can indeed be an indicator of a normal heartbeat, but other people may need a more intense heart rhythm due to the characteristics of the body.
