So, is it really reliable to say that the slower the heartbeat, the healthier the body and the longer the life? Come and have a look today!
heart rate
Heart rate refers to the number of heartbeats per minute of a normal person in a quiet state. In a quiet state of no exercise and emotional stability, the heart rate data of healthy adults is generally 60 ~ 90 beats/min. /kloc-tachycardia above 0/00, bradycardia below 60, arrhythmia below or above the normal range, which may hide major health problems. Therefore, it is not that the slower the heartbeat, the healthier the body.
In addition, affected by age, gender or other physiological factors, the heart rate will also have certain individual differences.
Generally speaking, the heartbeat of the elderly is slower than that of young adults, and it is normal to control the heart rate at around 55; If you have cardiovascular diseases such as hypertension, you should pay attention to monitoring the heart rate, which should be roughly controlled at about 60 times; In patients with cardiac insufficiency such as coronary heart disease, the heart rate should be controlled between 60 and 70, which is a normal physiological phenomenon.
The low heart rate of professional athletes is generally closely related to their long and arduous training experience. High-frequency and high-intensity training makes athletes' heart muscles strong, and each beat can pump more blood than normal people, so athletes' heartbeat is slower than normal people, and about 40 ~ 50 beats per minute can meet physiological needs.
The slower the heart rate, the better?
Actually, it's not. Low heart rate also increases the risk of heart disease. As we all know, if the heart rate is too fast in a quiet state, and the heart rate is higher than 100 beats/min, the risk of various cardiovascular diseases will increase obviously, so the risk of death due to too fast heartbeat will also increase.
But also, if your heart rate is too slow, which is lower than 50 beats/min for a long time, you may feel dizzy and tired because your heart is not pumping enough blood. At this time, I suggest you go to the hospital for a check-up in time, because low heart rate will also increase the risk of heart disease.
So the truth is that people with slow and stable heart rates are more likely to live longer. It is best to control the resting heart rate below 75 beats, but not below a limit, because a long-term slow heart rate can easily lead to insufficient blood pumping, which may lead to sudden death in severe cases.
In addition, we should not only look at the heart rate, but also look at the comprehensive indicators such as lung function, blood vessels and bones.
Harm of bradycardia
The heart of a normal person beats 60 ~ 100 times per minute. Bradycardia means that the heart beats less than 60 times per minute due to various reasons. In fact, bradycardia itself is not a specific sign, but if it is accompanied by chest pain, dizziness, syncope and shortness of breath, it is an emergency and you should go to the hospital for examination in time. So, what are the hazards of long-term bradycardia?
1. Affect cardiac function
Long-term, untreated slow heartbeat may lead to bradycardia and myocardial disease.
First of all, the heart structure will increase, and then the heart function will gradually decline, resulting in symptoms of limited heart function such as fatigue, shortness of breath, edema, decreased activity endurance, and inability to lie down at night.
Bradycardia may not only cause fatigue, chest tightness, shortness of breath and other symptoms, but also cause myocardial ischemia due to long-term insufficient pumping of blood by the heart, thus affecting heart function.
2. Affect the quality of life
People with bradycardia usually have dizziness, chest tightness, palpitation, fatigue, burnout, poor mental health and other symptoms.
When doing physical activity, because the heart rate can't be increased accordingly, the symptoms will be aggravated after the activity, which will cause syncope and convulsion in severe cases and affect the quality of life in severe cases.
3. Bring the risk of sudden death
If the heartbeat slows down for a long time and the pumping ability of the heart is not enough, the body will have symptoms of ischemia and hypoxia, and then it can only compensate for blood supply. When the ventricular movement exceeds the limit, the heart will return blood too slowly, which will lead to syncope and sudden death in severe cases.
How to check your heart rate?
The easiest way is to feel the pulse. Touch the radial artery15s in a quiet state, and multiply the pulse number of15s by 4 to get the pulse number per minute.
If the pulse beats irregularly or the heart rate is lower than 60 beats/min, or higher than 100 beats/min, it indicates that the pulse rhythm may be abnormal.
It is recommended to go to the Cardiology Department of Cardiovascular Specialist Hospital or General Hospital as soon as possible to avoid delaying the illness.
How to strengthen the heart
1. Reasonable daily exercise
Reasonable daily exercise is conducive to enhancing cardiopulmonary function and slowing down the deterioration of physical function.
Middle-aged and elderly people can stick to moderate exercise such as walking and jogging, and try to avoid violent sports with strong explosive force, such as sprinting and various antagonistic ball games.
Because middle-aged and elderly people generally have atherosclerotic plaques in different degrees, high-intensity exercise can easily lead to large fluctuations in blood pressure, plaque rupture and shedding, resulting in cardiovascular and cerebrovascular accidents such as cerebral infarction and myocardial infarction.
2. Emotion is stable, diet is light, and sleep is guaranteed.
Similarly, violent mood swings have similar risks. Therefore, we should maintain emotional stability in our daily life.
The daily diet should avoid overeating, and the food can be light.
Staying up late will accelerate the resting heart rate, so ensuring adequate sleep at night is also the basis for maintaining cardiovascular health.
3. Beware of caffeine and theophylline
In addition, it should be reminded that modern people have a fast pace of life and great pressure. Many people drink coffee and strong tea to refresh themselves.
However, caffeine and theophylline are easy to stimulate the heart. If you have palpitation and palpitation after drinking, it is best to reduce or suspend drinking.
4. Quit smoking and limit alcohol
The incidence of coronary heart disease in smokers is 36 times higher than that in non-smokers. Smoking has a synergistic effect with hypertension and high cholesterol, which can double the risk of coronary heart disease.
Drinking alcohol will accelerate resting heart rate, so quitting smoking and limiting alcohol will make our cardiovascular health better.
5. Keep a proper weight
Obesity will increase the burden on the heart, and you can maintain a proper weight by exercising and adjusting your diet.
Health tip: For patients with hypertension, coronary heart disease or heart failure, you should consult a specialized hospital to control the heart rate within the target value, which is conducive to controlling the disease.
