What causes a slower heartbeat? What causes a fast or slow heartbeat?

It is recommended to bring 24-hour ambulatory ECG monitoring to see if there is any serious arrhythmia, the sinus is a common cause and serious needs to install a pacemaker! Check it out!

If a person's heart beats less than 60 times per minute, it is "slow heartbeat", also known as "bradycardia". Normal people or athletes may appear, especially athletes, because regular exercise increases the contraction force of the heart, and the output of blood per beat increases, which is enough for the needs of various organs of the body, so the heartbeat of 50-60 times per minute is enough. However, if the heartbeat is only 30-40 beats per minute, it may be abnormal, and the cause should be investigated.

The first is vagus hyperfunction, in which there is a nerve center in the medulla oblongata of the brain that regulates cardiovascular activity. This center can have the function of suppressing the heartbeat or speeding up the heartbeat. The vagus nerve is the nerve fiber that is emitted by this center, which is used to innervate the heartbeat and other functions.

When the vagus nerve is excited, its terminals can release a substance called "acetylcholine" that acts as a depressant to the heart, slowing the heartbeat. The heart rate caused by "hyperactivity" is mostly regular, although the heartbeat is slow, it is rarely less than 30-40 beats per minute, and normal people, including the elderly, can appear.

The second type of slow heartbeat is called "sick sinus syndrome", or "sick sinus" for short. This is a pathological cardiac manifestation whose pathological changes occur mainly at the pacemaker of the heartbeat ——— the sinus node. The common ** is coronary heart disease, cardiomyopathy and degenerative diseases of the cardiac conduction system in the elderly.

Patients with "sick sinus" have a very slow heartbeat, sometimes only 30-40 beats per minute.

The third is the slow heartbeat caused by severe atrioventricular block, that is, the impulse wave sent by the original pacemaker sinus node cannot be transmitted to the atrioventricular node and is blocked, at this time the ventricle has to compensate for its own impulses, so the heartbeat is very slow, once complete atrioventricular block occurs, when the heartbeat is less than 20 times per minute, dizziness, and even fainting and convulsions can occur due to the obvious decline in cardiac blood output that directly affects the cerebral blood supply, which is a serious attack of Ass syndrome. Most of the causes of severe conduction block are organic lesions of the heart itself, such as coronary heart disease, myocardial lesions, or advanced severe changes in some heart diseases.

In short, when the heart beats slowly, it should be considered mainly from the main causes such as "hyperactivity", "sinus disease" and severe conduction block, and it can also be found through a detailed medical history and electrocardiogram examination to find the cause of slow heartbeat, so that it can be targeted.

Don't worry about it, it's all normal. Can you still keep your heart beating and your breath after running 100 meters?

Besides, people with fast heartbeats don't necessarily get sick. In fact, many times it is not the outside world that makes us sick, but the fear in our hearts that makes us mentally haggard.

Here's an example: last year, I was severely dehydrated due to excessive exercise. When I returned home, after taking a shower, I had general weakness, I fell to the ground with epilepsy, and was in a brief coma.

When I woke up, I was afraid I had epilepsy. It kept me struggling for days. In the end, I couldn't help but go to the hospital for a check-up, and it turned out that there was nothing wrong with it, and it was a great body.

It is a lack of vitamin B and potassium.

Normal heartbeat is between 60 and 100 beats per minute, life and work are too stressful, overworked, emotional, drinking more alcohol and not resting well at night may lead to rapid heartbeat, this situation is completely normal, and there is nothing wrong with you doing a checkup, don't think about it yourself, otherwise the nerve reflex will cause the heart to beat faster.

A normal heart rate is relatively constant, for example, 60 beats, and the heartbeat will fluctuate around 60 beats, but it will not be very large. If your heart rate is sometimes fast and sometimes slow, the following may occur:

1. Physiological state, such as the heart rate will be very fast when you are emotional or participate in sports, or the heart rate will slow down when you rest and sleep at night, which is a normal physiological fluctuation;

2. Pathological conditions, such as supraventricular tachycardia episodes, the heart rate will suddenly change from 60-80 beats to 150-200 beats. If atrial fibrillation occurs, it is an absolutely irregular arrhythmia, the heart rate will be fast and slow at the same time or in a short period of time, and the heartbeat will be felt fast and slow when the pulse is touched;

3. Other diseases can also affect the heart rate, such as hyperthyroidism or anemia, which will also increase the heart rate.

If you don't rest well, the heart rate itself will change with your mood and whether you are exercising or not.

The normal number of heartbeats is 60 to 100 minutes, and less than 60 is called bradycardia. There are several types of bradycardia, the most common being sinus bradycardia. Sinus bradycardia can be divided into pathological and physiological.

Physiological sinus bradycardia is a normal phenomenon, the general heart rate and pulse are 50 60 times, and athletes may have a heart rate of 40 times. Heart rate or pulse less than 50 beats is mostly pathological and needs to be **, and in severe cases, a pacemaker should be installed to speed up the heart rate.

What happens when you check your ECG and find sinus bradycardia?

1.For people who do not have heart discomfort, the pulse is 50 60 minutes, this sinus bradycardia is mostly physiological, that is, it is a normal phenomenon, and there is no need to worry about affecting health, and there is no need to **.

2.For people with heart discomfort, pay attention to the number of pulses when they are usually calm, and then count the number of pulses when the heart is uncomfortable, if the pulse rate is lower than usual every time you are uncomfortable, it means that your discomfort is caused by bradycardia, and you need to install a pacemaker to speed up the heart rate. You can also check the 24-hour ECG first to see how much slowest the heart rate is.

If the speed of the heart has heart discomfort, it does not matter, and the pulse is 50 to 60 beats, it means that there is no need for bradycardia, but other tests are needed to confirm whether you have heart disease.

The heartbeat is fast and slow, press and rub here for 3 minutes, the heart rhythm is normal, and the heart is relaxed and healthy!
