What is the ideal number of beats per minute for the heart? Longest life? Cardiovascular doctors give accurate answers!
The heart has been beating non-stop since we were born... One day, it stopped beating, stopped beating, and we said goodbye to this world!
So how many times does my heart beat per minute, ideally? Are we living longer?
Some people's heart beats only 50 times per minute, and they are very worried; some people can beat 180 times after the heart is active, I don't know if it is normal.
First of all, we tell you that under normal circumstances, when we say human heart rate, that is, the number of heart beats in one minute, it refers to the number of times our heart beats in a resting state.
When we were in school, the normal value of the heart rate was 60-100 beats per minute, that is, when the heart beats 60-100 per minute at rest, it is normal. If it is normal sinus rhythm, then on the basis of normal heart rhythm, less than 60 times is called sinus bradycardia, and more than 100 times is called sinus tachycardia.
But now this standard has been revised. The latest recommendation is that as long as the heart rate is not less than 50 times, it is normal, so people with a heart rate of 50 can rest assured.
But in real life, our heart rate is constantly changing:
- Fast or slow heart rate caused by heart disease
For example, various tachyarrhythmias or chronic arrhythmias caused by myocardial infarction, such as myocardial infarction treated in time, these arrhythmias will also recover, but if the treatment is not timely, it may be permanent or even fatal arrhythmias.
For example, tachycardia caused by heart failure needs to be corrected, and the heart rate will gradually decrease as the heart function improves. However, if the heart failure worsens and the heart rate is not fast, it means that the heart function is deteriorating.
- Heart rate changes caused by other diseases
In addition to heart disease itself, which can cause the heart rate to be too fast or too slow, other diseases can also cause heart rate changes. Such as infection, fever, shock, anemia, hypoxia, hyperthyroidism, cerebrovascular accident, etc. Of course, there are also drug reactions. Instead of treating the heart rate directly, treat the cause of the heart rate change first.
The heart rate of healthy people
Normal people also have a fast heart rate, such as after exercise, agitation, smoking, drinking alcohol, or drinking strong tea or coffee. Sometimes the heart rate is 120 times, or even faster, such as normal exercise heart rate up to 170-age, vigorous exercise heart rate up to 220 minus age. Generally, it is a normal or protective response, and the physiological nature is normal. The heart rate will gradually return to normal after you stop exercising, agitation, smoking, drinking, or drinking coffee. In these cases, the heart rate is too fast, which belongs to the self-protection behavior of the heart. , are normal. If you can't get up quickly at this time, it's broken, which means there is a problem with the heart.
Our normal heart is very smart, and it beats slowly during sleep, because the blood needed by the human body will be reduced during sleep, so the heart does not need to beat too fast, sometimes less than 50 times is enough, or even deep 40 times in sleep is enough; so a normal healthy heart should be fast or slow, not overworked or lazy.
Even 40 times in deep sleep is normal, about 60 times in quiet time is ideal, and it will get up quickly after activity, more than 120 times, or even faster to 220-age is also normal. If it should be slow or not, or if it should be fast, then there is a problem with the heart.
Although 50-100 beats are normal, a large number of studies have proved that within this normal range, the slower the heart rate, the better, that is, our heart rate is close to 60 beats/min when we are quiet, which is the most ideal.
Four, inexplicably fast and slow, be careful
There is no reason for the heart to beat too fast or too slowly. For example, when the heartbeat is fast at rest, and the average heart rate is greater than 100 beats, then there must be a problem, such as various tachyarrhythmias, sinus tachycardia, atrial fibrillation, atrial tachycardia, supraventricular tachycardia, etc., long-term cardiac arrhythmias It can also cause the heart to expand and cause heart failure, so it also needs treatment.
Or the heart rate is too slow at rest, or even sick sinus syndrome, atrioventricular block and other diseases, sometimes lead to black eyes, syncope, sudden death. These slow heart rates must also be treated aggressively.
- Ideal heart rate for common cardiovascular diseases
Myocardial infarction, angina pectoris, heart failure, we all want to control the heart rate at 55-60 beats. In this way, the mortality rate of myocardial infarction is the lowest, angina pectoris is less likely to occur, and heart failure is more stable. To simply control blood pressure, you must also control the heart rate. Only when the heart rate is lowered can the blood pressure be more stable. It is generally recommended that the average heart rate is greater than 80 times to reduce the heart rate.
Therefore, for our normal heart, 60-80 is ideal at rest; of course, it is normal if it is not lower than 50. And it should be slower during sleep and faster after exercise!
In short, a healthy heart should be fast or slow!
