Premature cardiac beats are a very common arrhythmia, why do hearts experience premature beats?

Because the early beating is caused by people's excitement, mainly heart disease caused by heart nerves or other reasons, drinking tea and exercising, constipation, excessive fatigue will be caused.

This condition is a form of heart disease caused by coronary atherosclerosis. Symptoms of premature contractions will appear.

It may be caused by staying up late and lack of sleep, or it may be caused by heart disease, such as coronary heart disease, or it may be caused by high work pressure and excessive mental tension.

Irregular work and rest, and unhealthy diet.

Premature cardiac contractions are conditions in which the heart closes prematurely before the normal time point of closure. Under normal circumstances, the cardiovascular system carries out fibrillation according to a certain law, and the interval between each retraction and the left ventricle is stable and consistent. Premature contractions can be divided into sinus premature contractions, atrial premature contractions, ventricular premature contractions, and borderline premature contractions according to the location of the contractions.

Premature contractions can be caused by physiology or by medical conditions. Thin and young people can have premature sinus contractions, and a variety of heart diseases can cause premature contractions. The main manifestations of palpitation, shortness of breath, chest tightness and shortness of breath, dizziness, and transient loss of consciousness may occur.

The key test for premature contractions is electrocardiogram (ECG) or 24-hour ECG monitoring, which produces a pattern that is abnormal during premature contractions.

Premature cardiac beats are the most common arrhythmias, which refer to the cardiovascular beats caused by too early and irrational transmission from the ectopic pacemaker of the heart. In other words, the electro-themed activity of premature beats does not arise from the sinus node, but from other regions, and it comes out early. Premature cardiac contractions are divided into atrial premature contractions, atrioventricular junction premature contractions, and ventricular premature contractions according to the location of ectopic premature contractions.

Among them, premature ventricular contractions are the most common, followed by atrial contractions, and junctional sex is rarer.

The symptoms of premature beats vary from person to person, some people don't feel anything, some feel palpitation, shortness of breath, heart rate stopping, heart rate about to burst out of the throat cage or cardiovascular sinking down, which will cause fear. Frequent premature beats that persist for a long time (due to decreased cardiac output), fatigue, dizziness and other conditions can cause or exacerbate myocardial infarction or chronic heart failure in patients with original heart disease.

The causes of premature cardiovascular contraction are physiological, and are more common in normal normal people, such as excessive exercise, overwork, staying up late, drinking too much freshly ground coffee and strong tea, emotional agitation, nervousness and anxiety, excessive smoking and drinking, etc.

Premature contractions caused by structural heart disease are caused by abnormal structure or function of the heart, such as myocardial infarction, rheumatic heart disease with mitral stenosis, chronic heart failure, heart disease, hypertrophic cardiomyopathy, hyperthyroid heart disease, hypertensive heart disease, mitral valve prolapse, etc.

Premature cardiac beats are a common type of arrhythmia, and the common causes are mainly seen in the following aspects:

1. Physiological premature contractions: seen in normal people, usually no pathological cause can be found, mostly appear in a quiet and relaxed situation, and disappear after activity. If some young people have premature beats but do not have hypertension, diabetes, myocardial ischemia and other diseases, it may be related to autonomic nerve dysfunction.

Some people also experience premature beats after drinking strong tea or coffee.

2. Pathology:

1. Cardiovascular diseases: such as hypertension, coronary heart disease, heart failure, and various types of cardiomyopathy, can show different types of arrhythmias, among which premature beats are more common;

2. Lung diseases: such as chronic bronchitis and emphysema, which will cause damage to the right heart system for a long time, which may be damage caused by hypoxia or increased direct pressure load, premature contractions can occur, and even premature beats may develop into atrial fibrillation;

3. Electrolyte disorders: such as abnormalities of blood potassium, blood calcium, magnesium, etc., premature beats will also occur;

4. Drugs: Some drugs can also cause premature beats.

There are many reasons for the formation of premature cardiac contractions, such as very unhealthy diet, or frequent emotional instability, smoking, drinking, and a particularly large labor force.

It may be because of the pressure at work, often staying up late and eating too much greasy, often drinking, often eating chili peppers, and not liking exercise will lead to premature heart beats.

Arrhythmia premature beats are caused by abnormalities in the heart's electrical conduction pathways, which may be caused by pathological diseases, such as coronary heart disease, myocarditis, electrolyte metabolism disorders, infections, or physiological factors, such as staying up late, being tired, drinking coffee, etc. The former causes needs**, while the latter is mostly self-healing.

Premature cardiac contractions are a type of arrhythmia and a more common type, which is divided into atrial premature contractions, ventricular premature contractions, and atrioventricular junction premature contractions. The severity of premature contractions is assessed according to the type and frequency of the attacks, and most importantly, the presence of a pathologic cause.

1.Pathological diseases may be cardiogenic diseases, such as coronary heart disease, myocarditis, etc., or extracardiac diseases, such as electrolyte metabolism disorders, infections, etc. Premature cardiac beats caused by these conditions need to be targeted at the primary disorder**, and if premature beats are frequent or cause symptoms, antiarrhythmic drugs** such as metoprolol may be given.

2.Physiological factors can also cause premature heart beats, such as overwork, staying up late for a long time, drinking coffee and strong tea, etc., these conditions are generally caused by occasional premature beats, there may be a sense of cardiac arrest, chest tightness, or no symptoms, most of them can be healed by themselves, but they are easy to recur.

If you have premature heart beats, you cannot determine the severity of your heartbeat, so it is recommended to go to the cardiology department of the hospital as soon as possible.

Premature beats are electrical impulses from the site of abnormal heart pacing that precede a normal heartbeat, and this extra beat affects the normal heart rhythm, also known as premature contractions, and is the most common type of arrhythmia.

Many normal people will have premature beats, generally do not have much danger, most of them belong to functional premature beats, usually pay attention to regular work and rest, relax more, and naturally can gradually relieve. However, there are some special types of premature beats that can be fatal and can lead to sudden death.

In atrial premature contractions, patients may present with chest tightness, fatigue, and a sense of cardiac arrest, but there are also some patients who do not have any uncomfortable symptoms. Most of the atrial tachycardia is not needed, unless there are obvious symptoms, or because the atrial premature triggers supraventricular tachycardia, and supraventricular tachycardia is relatively dangerous, and patients may experience syncope, myocardial ischemia, and pulmonary edema.

With premature ventricular contractions, patients may present with dizziness, fatigue, and chest tightness. In some patients, prolonged and frequent premature ventricular contractions may worsen angina, resulting in hypotension and heart failure. For premature ventricular disease with occasional absence of organic lesions, drugs are often not required**.

Patients with acute myocardial ischemia or infarction with premature ventricular infarction must be given aggressively** to reduce the risk of sudden death. Multifocal premature ventricular syndrome or paired and continuous premature ventricular disease is associated with a certain risk of sudden death, especially for the r-on-t phenomenon, which can easily induce ventricular tachycardia or ventricular fibrillation, resulting in sudden cardiac death.

When patients have symptoms of discomfort in the precordial area, palpitation, and palpitations, it is recommended that they should actively go to the hospital for examination to determine whether the disease is a functional lesion or an organic lesion, and choose to use drugs in combination to avoid adverse events.

For people at high risk of sudden death, the installation of an implantable cardioverter-defibrillator (ICD) is a more effective means of preventing sudden death. ICD is an electronic device that can identify and terminate malignant ventricular arrhythmias in time, which can automatically identify malignant arrhythmias such as ventricular fibrillation within ten seconds and issue electric shocks to defibrillation, saving the patient's life. The ICD is like an ambulance that you carry with you, guarding patients at all times and escorting them 24 hours a day.

Premature atrial contractions and arrhythmias are indeed not the same disease, but atrial premature contractions are a type of arrhythmia, and this conclusion can be drawn by comparison**.

Let's talk about the ** that causes premature atrial contractions:1Structural heart disease such as coronary heart disease, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, cor pulmonale, and heart failure; 2.

Extracardiac diseases such as infection, hyperthyroidism, adrenal gland disease; 3.Atrial premature contractions caused by the use of drugs such as digitalis, quinidine, epinephrine, or anesthetics. 4.

Mental tension, agitation, overwork, smoking, alcoholism, drinking strong tea and other bad behaviors may also cause atrial premature contractions; 5.Increasing age, pregnancy, hypertension, dehydration, etc. are also predisposing factors for atrial premature contractions.

Let's look at the onset of arrhythmia**There are two main categories: first.

1. Genetic factors, most of which are genetic mutations; Clause.

2. Acquired factors, including acquired physiological factors and pathological factors, of which physiological factors include tachyarrhythmia caused by behaviors such as exercise and mood changes, or slow arrhythmias due to behaviors such as sleep, pathological factors can be divided into three categories:1Cardiovascular diseases such as coronary heart disease, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, myocarditis, and congenital heart disease:

2.Systemic effects such as drug toxicity, acid-base balance, and electrolyte disturbances**:3

Changes in the functional structure of other extracardiac organs (e.g., hyperthyroidism).

There are similarities between atrial premature contractions and arrhythmias, atrial premature contractions can basically induce arrhythmias, but arrhythmia is not the main factor causing atrial premature contractions, so the two are not the same disease, but it can be said that atrial premature contractions are a special form of arrhythmia.

Premature beats are arrhythmias and are a common type of arrhythmia. Premature beats are not enough to cause any consequences, so there is no need to be overly concerned. However, it is important to pay attention to diseases that cause premature contractions.

For example, if you have coronary heart disease, high blood pressure, cardiomyopathy, rheumatic heart disease, severe heart failure, and premature beats caused by these reasons, you must pay great attention to them. There are many causes of premature contractions, so it is necessary to pay attention to the number of premature beats and make a comprehensive judgment.

Premature beats are a common arrhythmia, the normal heartbeat is 60 to 100 beats per minute, which is a regular beat, but if the premature beat, it will break this regular beat, then it will cause some symptoms of people, the most common symptoms are palpitation and palpitations. There are two main types of premature contractions, one is atrial premature contractions, the other is ventricular premature contractions, and the other is borderline premature contractions.

Hello, premature beats are often related to emotional agitation, mental tension, excessive fatigue, lack of sleep, excessive smoking and alcohol, drinking strong tea and other factors, this kind of premature beats are called functional premature beats; Premature beats caused by organic diseases of the heart itself, common ** such as coronary heart disease, acute myocardial infarction, myocarditis, wind heart disease, pulmonary heart disease, etc.; Certain drugs, such as digitalis poisoning, can also cause premature contractions. If you find that you have symptoms of premature contractions, you should go to the hospital for examination in time to confirm the nature and type of premature contractions and whether there are signs of myocardial ischemia, and it is recommended that a 24-hour Holter monitor and guide**. I hope you find my answer helpful and I wish you good health and happiness.

Premature beats are premature impulses from ectopic pacemakers that cause heart beats, which may be caused by factors such as coronary heart disease and myocardial ischemia. Pay attention to keep your mind relaxed and avoid mental tension and excessive anxiety.
