What to do about a low heart rate, what causes a person s low heart rate?

Recommendation: The patient is a 26-year-old male with "congenital hyporhythmia" and no symptoms.

A person's normal heart rate is 60 to 100 beats per minute, and when it is less than 60 beats per minute, it is called sinus bradycardia. It can be seen in healthy people, especially the elderly, athletes, and during sleep. With sinus bradycardia, the heart rate is not less than 50 beats per minute, and the patient is usually asymptomatic.

Low heart rate can lead to a decrease in blood pressure due to decreased stroke volume, dizziness, fatigue and even syncope, and in severe cases, angina pectoris or heart failure.

**: Heart rate above 40 beats per minute is mainly caused by increased vagus nerve tone, some drugs can also cause bradycardia, other causes include autonomic dysfunction, intracranial diseases, severe hypoxia, hypothermia, hyperkalemia and hypothyroidism and other pathological conditions.

**: If the patient is asymptomatic, it is not necessary**. When there is a symptom of insufficient blood output due to bradycardia, drugs such as atropine, isoproterenol and ephedrine can be used, and the cause of sinus bradycardia can be removed at the same time.

However, long-term use of drugs** is often inaccurate and prone to occur***.

Based on the information you provided, I think it is very likely to be caused by physiology, so you don't need to be too anxious, relax your mind, eat normally, and increase physical activity.

The rhythm of the heartbeat. The heart's autorhythmia allows it to beat rhythmically at a certain frequency. Normal regular heart impulses originate from the sinus node and travel to the atria and ventricles to cause the heart to beat.

The autonomic activity of the sinus node is regulated in vivo by nerves and humoral fluids. In addition to the sinus node, other autonomic tissues of the heart are driven by impulses from the sinus node and passively cause excitement before they are automatically excited, so these tissues generally do not show autonomic autonomy and become potential pacemakers.

When there is a disease in the heart or the cardiac nerve regulation is abnormal, the frequency and rhythm of the heart's beating will be disturbed, and this phenomenon is called arrhythmia. Arrhythmias can be physiological or pathological. There are three manifestations of common arrhythmias:

Sinus arrhythmia: Caused by a fast, slow, or irregular heartbeat from the sinus node. The frequency of impulses produced by the sinus node in normal people is 60 100 minutes, which is called sinus rhythm; More than 100 beats, sinus tachycardia; If the impulse frequency is less than 60 minutes, it is sinus bradycardia; Irregular impulsive discharge, called sinus arrhythmia.

Ectopic rhythm: when the activity of the sinus node is inhibited or its excitatory conduction is impaired, or the automaticity of the underlying pacemaker is too high, the potential pacemaker can show its automaticity and produce an ectopic rhythm. Such as premature contractions (premature contractions or extramature contractions), paroxysmal tachycardia, etc.

Conduction disorder: A part of the heart that doesn't conduct impulses properly. Also known as conduction block.

Atrioventricular block is the most important and common block. Pathological arrhythmias, which affect the normal ejection function of the heart. Central ventricular fibrillation is a serious arrhythmia in which the ventricles beat quickly and irregularly, about 150,300 beats per minute, causing the ventricles to lose their ability to eject blood, with the same serious consequences as cardiac arrest.

The heart is very important to the human body, determines the normal operation of the body, as long as you are alive, there will be a heartbeat, if there is no heartbeat, it also means the end of life, so the beating of the heart is also a problem that everyone should pay attention to.

The beating speed of the heart has a certain impact on the health of the body, and too slow or too fast will be harmful, and the heartbeat of a normal person will be harmedBetween sixty and one hundred beats per minuteIf it is more than 100 beats, it means that the heartbeat is too fast, and if it is less than 60 beats, it is considered a slow heartbeat.

However, many patients will wonder if their heart rate is only more than 50, is it abnormal and harmful to the body? In fact, it is not what everyone thinks, first of all, we must understandSinus rhythmOn the basis of sinus rhythm, it is necessary to judge whether there is danger according to everyone's own situation. Although the normal medical regulations are 60-100 times per minute, our heart is a dynamic symptom, after exercise is different for everyone, it may also be related to lifestyle habits, as long as there is no pain, dyspnea and other diseases, then it is safe, so don't think too much.

So, what causes a slow heartbeat? You may wish to understand these reasons.

Causes of bradycardia

Cause 1: Atrioventricular block

The impulse wave emitted by the sinus node of the heart is blocked, and it is difficult to reach the atrial node, so the heart can only send out impulses on its own, and there will be a slow heartbeat, and in severe cases, it will also lead to some coronary heart disease, cardiomyopathy and other diseases.

Cause 2: Sick sinus syndrome

It is a manifestation of heart disease, mainly occurring in the sinus node, mostly in the elderly, and the heart beats only thirty or forty times per minute.

Reason 3: Vagus nerve hyperfunction

It is a nerve center that regulates cardiovascular activity in the human brain, which can inhibit the heartbeat of the human body, and when this nerve is excited, it will release a substance that inhibits the heart and slows down the heartbeat.

How should I adjust my heart rate if my heart rate is too slow? First, the patient needs to rule out whether it is or notPathological causesIf this phenomenon is caused by illness, you can take some medicine to recuperate, which is commonAtropineetc., it can be a good way to alleviate abnormal heart beating, but it should be noted that you must listen to the doctor's advice and do not buy it without authorization.

If it's becauseSelf-constitutionThe reason for that, that's neededTone the bodyEat more vegetables and fruits, foods containing high protein, supplement vitamins, exercise properly, and long-term persistence will improve to a certain extent.

Finally, I would like to remind everyone to pay attention to their heart health in their daily life, do a good job of prevention, and reduce the occurrence of diseases.

A normal heart rate ranges between 60 and 100 beats, and anything below 60 beats is called bradycardia. Causes of bradycardia include both physiological and pathologic causes. Physiologic causes are vagus nerve excitation or a slow heart rate that may occur during sleep; Pathologic causes include hypothyroidism, hypothermia, concomitant cerebrovascular disease, or atrioventricular block.

Different pathogenic causes require different management strategies.

Normal heart rate is mainly related to age and physical fitness. People like athletes or people who have been engaged in heavy physical work for a long time have a lower heart rate than the average person.

A person's low heart rate can be caused by hypothyroidism, which medications can be taken by the doctor.

What causes a slow heartbeat.

Conduction block. In general, severe atrioventricular block causes a slow heartbeat, that is, the impulse waves emitted by the pacemaker sinus node cannot reach the atrioventricular node, so the ventricles have to compensate for their own impulses, and therefore, the heart beats slowly.

Once complete atrioventricular block occurs, when the heartbeat is less than 20 beats per minute, dizziness, and even fainting and convulsions may occur due to a significant decrease in cardiac blood output, which directly affects the cerebral blood supply, which is a severe 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.

Altered vagus tone.

Bradycardia caused by increased vagus tone is common in normal people, and when the vagus nerve is excited, its endings can release a substance called "acetylcholine", which acts as a depressant effect on the heart, so it can slow the heartbeat. Although the heartbeat is slow, it is strong and regular, and it is not less than 50 beats per minute, the cardiac output does not decrease, and it can maintain normal physiological functions.

Changes in sinus node function.

The slow heartbeat due to the lesion of the sinus node itself is called sick sinus syndrome, and the heartbeat is about 40 beats per minute. The cardiac output is significantly reduced, and people will have symptoms such as dizziness, dizziness, and tinnitus. In severe cases, coma and convulsions may occur.

What to do if your heart beats slowly.

If the heart rate is not a big problem, it is generally okay if it is more than 50 beats and there are no symptoms.

The most common causes of bradycardia are pathological sinus bradycardia, sinus arrest, sinus block, atrioventricular block. Pathologic sinus bradycardia is characterized by an uncomfortable bradycardia. **Most people have sick sinus syndrome, acute myocardial infarction, hypothyroidism, increased intracranial pressure, or use of drugs that slow the heart rate.

It is also a kind of heart disease, so you should pay attention to rest and do not eat greasy and high-fat ones.

Insufficient blood supply to the myocardium caused by insufficient qi and blood, bradycardia.

Hello, a low heart rate of 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 is 50 60 times, athletes may have a heart rate of 40 times, no **, common in normal people sleep, people with more physical activity. Sinus bradycardia, if the heart rate is not lower than 50 per minute, there are no symptoms, such as the heart rate is less than 40 beats per minute, it can often cause symptoms such as angina, cardiac insufficiency, or syncope. Need**, medication**, and in severe cases, a pacemaker should be installed to speed up the heart rate.

A normal person's heartbeat is about 60-100 minutes, if it is lower than this heartbeat, the heartbeat is slow, and the slow heartbeat has the following conditions. The first may be individual differences, some people are born slow, some people are born fast, there are some individual differences, generally speaking, as long as it is more than 50 times, are there any corresponding symptoms? For example, dizziness, fatigue, or chest tightness associated with a slow heartbeat are generally considered normal.

The second situation is that the heartbeat of people who exercise regularly is a little slower, especially long-distance runners, generally speaking, the heartbeat will be a little slower than others, which is also a normal phenomenon. The third situation is pathological problems, the heartbeat is affected by myocarditis, myocardial infarction or insufficient blood supply, there are organic problems in the heart, and then affect the conduction system, and then affect the slow heartbeat, so that there is a pathological basis for slow heartbeat, often there are some corresponding symptoms, at this time should be further detailed examination, evaluation, and then do symptomatic**.

Check the blood potassium, and if it's okay, take a look at Chinese medicine.

It is better to go to the hospital to do an "atropine experiment".

If it's positive, it's going to be **.

There are too many spring dreams, and this is the reason.

A normal heart rate of 60 to 100 beats per minute, which is a relatively small number of heart rate and usually causes heart discomfort.

The heart rate is too slow to affect the blood in the whole body**, and the common ones are sick sinus syndrome, and in severe cases, a pacemaker is required.

The normal heart rate is 60-100 beats per minute. Less than 60 beats is called sinus bradycardia. It can be divided into two types: common sinus bradycardia and sick sinus syndrome.

If the heart rate returns to normal with atropine, it is sinus bradycardia, referred to as sinus bradycardia, which is basically a normal phenomenon; Otherwise, it is a sick sinus syndrome, referred to as a sick sinus, which is an abnormal condition.

Analysis: Hello. Under normal circumstances, the heart rate is generally 60-100 beats per minute, and some people, especially athletes and other healthy people, may have a lower heart rate, and if there are no symptoms, they can not be treated.

Your "low heart rate" is considered to be a "bradyarrhythmia", a type of arrhythmia. There are a variety of reasons that can be caused, such as coronary heart disease, hypertension, cardiomyopathy, myocarditis and other organic diseases, drugs, electrolyte imbalances and other factors, etc., you now have dizziness, nausea, indicating that the heart rate slows down caused by insufficient blood supply to the brain and other organs, it is necessary to see a doctor in time for treatment.

Guidance: It is recommended that you go to the hospital immediately for a detailed examination, preferably including electrocardiogram (re-examination), holter (24-hour electrocardiogram monitoring), biochemical tests (liver and kidney function, electrolytes, cardiac enzymes, blood glucose), blood routine, cardiac ultrasound, and if necessary, further examinations. It needs to be clarified before it can be further developed.

The doctor asks: What is also necessary to clarify: what is your heart rate, whether there are other abnormalities in the electrocardiogram, whether you have a recent history of medication, whether there are triggers before the onset of the disease, whether there is a previous medical history, etc.

The heart rate is less than 60 beats per minute and varies according to the state of the human body. If there is a problem with the heart, the heart rate cannot increase with the body's needs, and it will affect the whole body. if rested (resting, inactive), or in general of daily living; If the heart function is normal and the heart rate is sinus rhythmic, the heart rate is less than 60 beats per minute and has no effect on the body.

Because the cardiac output under the condition of heart rate can fully meet the needs of the human body's blood supply. (Sinus rhythm is the normal rhythm of the human heart, and the heart rate range of sinus rhythm is 60 100 beats per minute, and some experts believe that it can be 50 to 90 beats per minute.) If there is an increase in physical exertion, sports, or activity; Either in a state of hypoxia, or metabolism increases, the whole body needs to increase blood**, the heart rate will increase (heart rate increases fast), and cardiac output will increase (within a certain heart rate range) to meet the needs of the body.

In this case, if the heartbeat is lower than 60 beats per minute and cannot be accelerated, it will cause a shortage of blood in the whole body**, people will feel tired, chest tightness and shortness of breath, and they will not be able to work, exercise, and lack of oxygen will not be relieved. If cardiac function is reduced, the output per beat (output per beat) decreases; The heart needs to work faster and the heart rate needs to increase faster to meet the total amount of blood**. If the heart rate is less than 60 beats per minute, the heart rate does not increase quickly and does not meet the need.

This can lead to circulatory failure due to heart failure.

Therefore, in diseases such as hypoxia, heart failure, etc., heart rate control is not too slow. Because heart rate is related to cardiac output, if the heart rate is too slow, or if the heart rate does not increase with the body's demand, the main effect on the body is due to the lack of blood to the body**.
