How fast does the human heart beat?

At rest, the heart beats at a rate of 60 75 beats per minute, and after a lot of exercise, the heart beats at a rate of 130 beats per minute or more, and then returns to the speed at rest. The speed at which the heart beats varies depending on the needs of the body. Every time the heart beats, blood is pumped into the blood vessels and the blood vessels bulge, |This bulging process can be felt on the wrist and is known as a pulse.

Your doctor will measure your blood pressure during and between heartbeats to determine how healthy your heart is. The number of heartbeats in adults is normal within 60-100 beats per minute, but the average person takes the median value, and the majority is in the range of 70-90, among them, men jump slowly, women jump fast, emotional and athletic fast jumps, rest and idle slow dance. For children, the heartbeat is generally faster, most of them are between 90-130, and the younger they are, the faster the heartbeat tends to be, which is a common sense.

As a professional athlete, the heartbeat is relatively slow, only about 60 times per minute, and there are some adults with heart disease who have a heartbeat of more than 100, or even 120, which is a tachycardia, which is problematic and needs to be seen a doctor. The heart rate is too slow, due to the lack of blood "pumped" by the heart, resulting in hypoxia and ischemia in the human body, and the compensatory ventricles speed up the movement to supply blood, and the ventricular movement is too fast, which will cause insufficient blood return, and in severe cases, it may lead to sudden death or even death in sleep. Therefore, if the heart rate and pulse are less than 50 beats, you should go to the hospital for a detailed examination to find out the cause, and if it is pathological, a pacemaker should be installed to speed up the heart rate.

A fast heart rate can also shorten your life. Because the heartbeat is too fast, it is equivalent to quickly depleting the "total heartbeat" of the human body in a lifetime. Long-term tachycardia can lead to heart enlargement, heart failure, and a history of coronary heart disease will directly induce coronary heart disease attacks, thereby increasing the morbidity and mortality of cardiovascular disease.

Especially for people with high blood pressure, it is best not to have a heart rate of more than 80 beats. Once the heart rate exceeds 100 beats, you should go to the hospital in time to find out the cause and **. If you want to slow down the heart rate, you should pay attention to reducing work pressure and mental burden, obese people should lose weight, exercise more, eat a low-salt diet, quit smoking and avoid alcohol, etc.

Pathological causes that lead to rapid heart rate such as infection, fever, anemia, hyperthyroidism, cardiac insufficiency, etc., should occur in a timely manner. It should be reminded that the three-high people must exercise moderately, if they can't recover to less than 100 points after 5 minutes after the end of exercise, it is too intense.

We know that the function of the heart is to pump blood, when exercising, the demand for oxygen increases, oxygen is transported by the blood, and the blood flow of the muscles increases during exercise, which requires the heart to beat faster to increase the pumping volume. If the heart pumps more blood per beat, then the heart can beat a few less. Otherwise, the heart needs to beat fast.

The amount of blood that a heart can pump out in one beat is called stroke volume. Stroke volume also increases during exercise in order to pump more blood. However, current research generally suggests that the average person, from a resting state to the beginning of exercise, has a faster heart rate and an increase in stroke volume.

However, when the exercise intensity reaches 40-60% of the VO2 maximum, the stroke volume no longer increases, and the only way to pump more blood is to increase the heartbeat. However, for high-level endurance athletes, the stroke volume will continue to increase as the exercise intensity increases until the maximum exercise intensity, so endurance athletes generally have a slower heartbeat during exercise. Even when not exercising, the heart tends to beat more slowly.

The heartbeat can tell the lifespan of a person, which is actually based on this science, we can know that the heartbeat rate of rodent creatures is more than 300 to more than 500 beats per minute, but how long do they live? Under normal circumstances, 1 2 years may be 1 2 years, but there is another set of data that shows that turtle creatures only beat their hearts 6 or 10 times per minute or even less, but they will live for at least 100 years! It can be seen that the lifespan of living beings is closely related to the beating speed of the heart, although some people may think that it is just an animal, but in fact, we humans are not also a kind of primate animals!

As long as it is a living being, then this law is universal, so if you want to live a long life, you must control the speed of your heartbeat.

Analysis: Heart rhythm: Modern Chinese interprets "heart rhythm" as:

The rhythm of the heart when it beats. "A normal person's heart should be able to beat rhythmically and regularly. There is a certain time interval between each beating and the next beat, and the interval between each beating does not exceed a second, which is regarded as normal in medicine.

For some reason, there is an irregular change in the rhythm or rhythm of the heartbeat, that is, when the rhythm is inconsistent, it will be shown on the ECG, which is what doctors often diagnose for us: arrhythmia. It's not a big deal.

Because there is an error in the interval between heart beats. As long as the Nian Brother stove does not exceed its range, it is normal. The starting point of the heartbeat, also known as the pacemaker, is a special tissue in the heart called the sinus node, so when there is nothing wrong with the normal heartbeat, that is, the rhythm or rhythm of the heartbeat, doctors often diagnose you as:

Sinus rhythm. So don't worry about sinus rhythm or sinus arrhythmia. If there is a serious disturbance in the rhythm or rhythm of the heartbeat, it is usually due to structural heart disease and you should seek medical attention.

Heart rate: Modern Chinese interprets "heart rate" as: "The frequency at which the heart beats."

That is, the number of times the heart beats in a certain time. A normal adult has a heartbeat of 60,100 beats per minute. The change in between, for example, yesterday your heart beat 80 beats per minute, but today your heart beats 85 beats, or 70 beats, doesn't make medical sense, don't care.

More than 100 beats per minute is a fast heart rate, also known as tachycardia, or rapid heart rate; If it is less than 60 beats per minute, it is a slow heart rate, also known as bradycardia, or bradycardia. Whether the heart rate is too fast or the heart rate is too slow, it is caused by the arrhythmia of the heart's beating.

The heart pumps 80ml of blood in one beat, the average pressure to promote blood flow is 16kpa, and the work is 80e-6 16e3;

70 beats per minute, the heart because of the output, a total of 1440 minutes a day, that is, a day of heart to maintain beating energy, need to consume 129024j 80 2804kj c6h12o6 molecular mass of 12 6 12 12 16 6 180, that is, 1mol of glucose weighs 180g, that is, the heart beats a day to consume glucose.

As for how many liters of oxygen need to be consumed every day to maintain life, I think it is a logical error, life is characterized by metabolism, and the beating of the heart is only a part, if as the title implies, then how much oxygen reserves in the blood come out of the lungs, and how much is returned to the lungs, only the need for the heart to beat will be consumed, then the blood circulation system will become meaningless idling, and other parts of the body will not be able to draw energy from it, even if it is a vegetative person to maintain the lowest level of energy consumption, I am afraid it will be an instant death.

Analysis: Hello, there are significant individual differences in the heart rate of normal adults at rest, with an average of about 75 beats, and the heartbeat of adults is about seventy or eighty beats per minute, but it is normal between 60 and 100 beats.

Guidance: Jump faster than when you are quiet, women jump faster than men, and children jump faster than adults.
