What is a normal heart rate?

We who have studied biology all know that heartbeat is very important for our body to obtain oxygen, and the frequency of heartbeat affects the amount of oxygen we absorb. There is no accurate definition of what is considered a normal heart rate range. For adults, a heart rate of 70 to 80 is relatively normal. The heart rate also increases during exercise, which is normal.

Of course, for some patients, regular use of some stimulant drugs may also cause a slowing of the heart rate. People who are emotionally excited or panic-stricken may feel their heart rate accelerate and their oxygen absorption decreases. At this time, we should control our emotions.

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.

Generally refers to the number of heart beats per minute. There are significant individual differences in the heart rate of normal adults at rest, with an average of around 75 beats/minute (between 60 and 100 beats/minute). Heart rate can vary depending on age, gender, and other physiological conditions. The heart rate of a newborn is very high, reaching over 130 beats per minute. Among adults, women generally have a slightly faster heart rate than men. For the same person, the heart rate slows down when the person is at rest or sleeping, and speeds up when the person is exercising or emotionally excited. Under the influence of certain drugs or neurohumoral factors, the heart rate can speed up or slow down. People who regularly engage in physical labor and exercise usually have a slower heart rate.

Heart rate: A normal person's heart rate should be between 60 and 100 beats per minute. Any higher or lower than this is considered abnormal. But the heart rate varies at different ages. The heartbeat of the elderly over 60 years old can be slowed down, but the slowest cannot be lower than 50 beats per minute. For athletes or those who do heavy physical labor, the heart rate can be around 45 beats per minute because the cardiac output is significantly larger than that of normal people. Fever, emotional excitement, mental tension, intimidation, etc. can all cause the heart rate to increase at one time, which is a reflection of the body's normal regulation. In short, the speed of your heartbeat can reflect your heart function. A strong, powerful, regular, coordinated heartbeat is one of the signs of good heart function.

Rhythm: The heart is responsible for the blood supply to all organs in the body. Through the strong beating of the heart, the oxygenated blood is continuously transported to all parts of the body for metabolism, keeping people in a full and energetic state. For a normal person, the difference between each heartbeat should not be greater than 0.12 seconds. Obvious unequal rhythm is evidence of heart disease. If there are excessive and long-term intervals, it is likely to be various conduction blocks. You should go to the hospital in time to check the electrocardiogram, make a clear diagnosis, and take medication as soon as possible.

For patients with frequent abnormal heart rhythm, they must pay attention to proper exercise, which can relieve symptoms. To improve the heart's beating ability, patients with heart disease should avoid excitement. Patients need to have regular physical examinations. It is very important to control the symptoms and development of the disease in a timely manner.
