I m 17 years old, and my heart rate is usually 51 57 beats, is it normal?

It's not normal, you need to check out what** is causing your tachycardia, only by finding out** you can be completely good,

You may want to consider seeing a doctor.

This is not normal, and this symptom should be an irregular heartbeat.

Many arrhythmias have no symptoms. If there are symptoms, they are generally the following:

1. Palpitations (a type of heartbeat that the patient can feel faster and worse) 2. Slow heartbeat.

3. Irregular heartbeat.

4. The heart pauses between heartbeats.

Arrhythmia caused by serious diseases is often accompanied by some symptoms, such as dizziness, chest tightness, chest pain, shortness of breath, excessive sweating, paleness, cold limbs, convulsions, coma, etc. Slight arrhythmia can still work as usual and tremble early to learn to search the cave.

As soon as you see the word sinus, you should know that this is a normal heart rhythm, and it is easy to understand that it is too slow. This conclusion is easy to understand, but the explanation around it is not so simple. For the normal number of heartbeats in adults, textbooks always say 60-100 beats, which means that if your ECG shows that your heartbeat is less than 60 beats per minute, then the ECG doctor will write a report:

Sinus bradycardia. It should be said that the artificial belief that 60-100 beats per minute is normal, and that it is not normal to be lower or higher, should be said to be inappropriate. Now the general view is that a heartbeat of 55 to 90 beats per minute is appropriate at rest, so it is normal to say that the number of heartbeats above 55 beats is normal, and you don't have to worry.

If it is between 50 and 55 times, it can be closely observed, and no special treatment is generally required. If it is less than 50 times, you will need to go to a cardiovascular specialist. There are many factors that can cause a slow heartbeat, there are normal, untreatable situations, and there are also very dangerous situations.

I'll start with normal. I'll tell you about the abnormalities in the future in the content about pacemakers. The most common condition that causes a slow heartbeat is a person who regularly does physical exercise, his heart rate is slow, and the heart rate of a professional athlete at rest can drop to 40-50 beats per minute without any symptoms, which has no effect on his body.

This is easy to understand, because his heart is constantly exercising, and the amount of blood that his heart beats out is equivalent to the amount of blood that our ordinary people's heart beats twice, so his heart beats slowly. For example, Bush Jr., the former ** of the United States, has a heart rate of only about 45 beats at rest, which is related to his long-term insistence on jogging and cycling. There is also the case of taking drugs that cause the heart rate to drop.

Guidance: Hello! The number of normal heartbeats is 60 100 minutes, less than 60 is called bradycardia, there are several types of bradycardia, the most common is sinus bradycardia, which can be divided into pathological and physiological two, physiological sinus bradycardia is a normal phenomenon, the general heart rate and pulse are 50-60 times, athletes may have 40 times of heart rate, do not need **, common in normal people sleep, people with more physical activity.
