Fast or slow heartbeat is not good
Sudden deaths of young and middle-aged people are mostly caused by ventricular arrhythmia
More and more young and middle-aged people die suddenly. Professor Huang He from the Department of Cardiology, People's Hospital of Wuhan University said that most of them are caused by ventricular arrhythmia.
Ventricular arrhythmia is just a manifestation of the heart beating.
The "Zhangjianzhi" column specially invited Professor Huang He to talk about why the heart beats and how to keep it from beating.

Normal heartbeat 60-100 beats per minute
The heart is known as the engine of the human body. It pumps blood that has been oxygenated through the lungs and carries rich oxygen to the whole body to nourish the organs and tissues of the whole body, day and night.
Professor Huang He told "Zhang Jian Zhi" that this action of the pump requires rhythmic contraction and relaxation. The rhythmic contraction and relaxation of the heart shows the pulse and heart rate of the human body.
"Our heart rate has a range under normal resting conditions, for example, from 60 beats per minute to 100 beats per minute, which is a range that we can accept." Professor Huang He specifically pointed out that it will be exceeded under special circumstances. In this range, jump faster or slower.
When we sleep at night or rest during the day, the other organs of the body do not need more blood supply, so the heart can not do so much work and will beat slower.
Some people's heart rate will drop to about 50 beats per minute at night, Professor Huang He told "Zhang Jian Zhi", "This is also allowed."
Corresponding to slow is fast. When a person is excited or exercising, his heart rate can reach 150 beats per minute. "This is also acceptable."
Professor Huang He emphasized that 60 beats per minute to 100 beats per minute is a normal heartbeat interval.
A fast or slow heartbeat is called arrhythmia
The normal heartbeat is rhythmic, like a music beat, very neat.
Professor Huang He told "Zhang Jianzhi" that a person's heartbeat is fast, too slow, or beats at rest, which is collectively called arrhythmia in medicine.
There are several types of causes for arrhythmia: congenital causes are brought from the mother’s womb, some people will have attacks when they are very young, and some people will not have attacks until old age; myocardial ischemia and coronary heart disease will also occur. Lead to arrhythmia; as the age increases, the body's organs and tissues such as myocardium degenerate or the disease brings some heart disorders. This is the most common cause of arrhythmia in the elderly.
Arrhythmia can occur at different ages. Due to the different types of arrhythmia, the corresponding population and incidence rate are also different.
There is a kind of arrhythmia which is rapid in nature. It is called paroxysmal supraventricular tachycardia in medicine, which is more common in young and middle-aged people; atrial arrhythmia has a higher incidence in the elderly; and ventricular arrhythmia is in the absence It is more common in patients with bloody coronary heart disease.
The familiar premature beats can be seen in patients of all ages.
"Ventricular arrhythmia is the most dangerous, because it may cause sudden death." Professor Huang He told "Zhang Jianzhi". We often learn in the news that marathon runners fell to the ground and died suddenly during some competitions. Most of them happened. This malignant arrhythmia-ventricular arrhythmia.
The most important routine method to rescue ventricular arrhythmia is external defibrillation.
If such patients are lucky enough to be rescued, a device must be implanted in the patient's body. This device is called an embedded automatic defibrillator (ICD). Once the patient suddenly dies again, this device can act like an external defibrillator. The role of defibrillation can save the patient's life in time.
It's dark in front of me, it may be an arrhythmia
The largest and most basic function of the heart is to pump blood throughout the body.
If the heart has arrhythmia, the function of pumping blood cannot be completed well, and a series of symptoms will appear on the body.
Professor Huang He specifically described two symptoms that are not easily noticeable to "Zhangjianzhi".
Palpitation: When an arrhythmia occurs, the lightest feeling is palpitation. This palpitation is a panic that beats fast, and a panic that beats slowly is also a panic.
At this time, you can feel your pulse, or use a blood pressure measuring instrument to measure your heartbeat. There are also some wristband watches that can also record your heartbeat.
Palpitations: This is a symptom that is difficult to describe. It is a little bit stuffy, and even a little bit painful, but the description is not clear. This is a broader range.
If the arrhythmia beats faster or slower, the eyes may appear dark, which is medically called amaurosis.
If there is hazy, the degree of arrhythmia is a little more serious than the above two symptoms.
If you faint, then the severity of the arrhythmia is more serious on the basis of amaurosis, because the arrhythmia has caused hypoxia and ischemia in the brain.
The most serious consequence of arrhythmia is sudden death.

Arrhythmia prevention and control methods
Arrhythmia can be prevented and controlled through self-management.
Professor Huang He told "Zhang Jianzhi" that there are many factors that cause arrhythmia. In fact, we can control and manage these factors to reduce the incidence of arrhythmia.
Manage emotions: Don't get too excited, especially for patients with high blood pressure and coronary heart disease. Usually, you must control your emotions and keep them from going up and down.
Regular work and rest: There should be regular living habits, such as when to sleep, when to get up early, and when to exercise. Everyone has their own regularity of life. Once this regularity is broken, it will cause arrhythmia, including arrhythmia, and heart disease. Some related diseases.
Eat a reasonable diet: Alcohol, coffee, and strong tea all have the effect of increasing heart rate, and long-term heavy drinking may also cause arrhythmia.
Regular physical examination: Many diseases do not necessarily have symptoms, and physical examination is very important.
Many basic diseases can be found through physical examination, such as increased blood pressure and metabolic problems, which are the basic pathogenic factors of cardiovascular and cerebrovascular diseases. If early detection and early treatment, these coronary heart diseases and arrhythmias will be reduced clinically.
