27-year-old female heart rate 100

We all know that under normal circumstances, the human heart beats between 60 and 100 times per minute. A heart rate below 60 is generally called a bradycardia, and a heart rate above 60 is called a tachycardia. This can easily cause an irregular heartbeat, especially for some young people. Having heart disease is very dangerous. So, is it normal for a 27-year-old woman to have a heart rate of 100?

The normal rate for a normal person at rest is 60-100 times per minute.

There are significant individual differences in heart rate. Heart rate varies with age, gender and physiological conditions. The heart rate of a newborn can quickly reach over 130 beats per minute. It gradually slows down with age and approaches that of an adult during adolescence. Among adults, females are slightly faster than males.

People who often engage in physical labor and physical exercise usually have a slower heart rate, but their heart rate speeds up during strenuous exercise or when they are emotionally tense.

An adult's heart beats about 70 to 80 times per minute, but 60 to 100 beats per minute is normal. The heart beats faster when working than when resting, women beat faster than men, children beat faster than adults, and newborns can beat up to 150 times per minute. On average, if a person lives to be 100 years old, his or her heart beats a total of about 4 billion times.

Normally, if an adult's heart beats more than 100 times per minute at rest, it is medically considered "tachycardia"; if it is less than 60 times per minute, it is considered "bradycardia". Some people's heartbeats may speed up, slow down, or stop and start. These all fall within the range of abnormal heartbeat. Abnormal heartbeat is one of the symptoms of heart disease.

However, like many organs in the body, the heart's working capacity can vary and it has a lot of room for flexibility.

According to research, if you do a set of radio gymnastics carefully, your heart rate may increase by 20 to 30 beats per minute. When people are angry or afraid, students' hearts will beat faster when they are about to enter the examination room. Athletes climbing Mount Everest have a heart rate of 170 to 180 beats per minute. If some people are asked to run 300 meters with a 30 kg weight, their heart rate will exceed 200 beats per minute. Medical records show that the heart rate was as high as 270 beats per minute.

The purpose of speeding up the heartbeat is to pump more blood to meet the body's needs for labor, exercise and special circumstances. If the heartbeat is too slow and the blood supply is insufficient, the body will not get the necessary oxygen and nutrients and people will not be able to live a normal life, and even more serious consequences may occur.

Physiologists have found that people who engage in heavy physical labor and intense exercise for a long time have their hearts exercised and their heart rate is much less than that of normal people. There is a football player in our country today whose heart beats only 37 times per minute; in the 1928 Olympics, there was an athlete whose heart beat only 28 times per minute. It turns out that people whose hearts get better exercise have larger myocardial fibers, thicker ventricular walls, and larger hearts themselves. After a former British world marathon champion died of cancer at the age of 70, doctors found that his heart was about 30% heavier than a normal person's, and the blood vessels supplying it, the coronary arteries, were about 1 times thicker. Such a heart naturally contracts very strongly and powerfully, and the amount of blood delivered to the whole body with each beat is many times more than that of an ordinary person. Therefore, although the heart beats less, the body's normal needs can be met due to the abundance of blood.
