By how many contractions our heart makes in one minute, you can find out how healthy we are. For example, a fast heartbeat can signal that a person has problems with the nervous system and immunity. If a person's pulse has dropped, 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 the development of serious diseases in patients.
The new discovery of scientists from the United States was written in the scientific 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 of about 46 years and that they wore a heart rate bracelet throughout the year. As it turns out, the "normal" heart rate may differ from person to person. If for one person 60 beats per minute is the norm, then for another such a heart rate can be a signal for the development of cardiovascular diseases.
How many beats per minute does a human heart make?
In the course of studying the data of 92 thousand participants in the study, it turned out that the heart rate in humans fluctuates 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 50 to 80 beats per minute, and that of women - from 53 to 82 beats per minute.
According to scientists, factors such as age, body weight and the presence of bad habits such as excessive alcohol consumption and smoking can affect the heart rate. At some times, people experience dramatic 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. Also, changes in heart rate have been seen in different seasons of the year. For example, in January, people's hearts beat faster than in June.
Ultimately, scientists concluded that such a thing as 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 may indeed be an indicator of a normal heartbeat, but other people, due to the characteristics of the body, may need a more intense heart rate.
