What is the cause of irregular heartbeat? Pay attention to arrhythmia

Many organic heart diseases can cause arrhythmia, such as coronary heart disease, myocarditis, cardiomyopathy, as well as neurological disorders, drug effects, systemic diseases, especially arrhythmia caused by organic heart disease, which should be treated as soon as possible.

1. Various organic heart diseases

Such as congenital heart disease, coronary heart disease, valvular heart disease, myocarditis, pericarditis, cardiomyopathy, endocarditis, etc., because the heart's sinoatrial node and conduction system are affected by the lesions, arrhythmias are very likely to occur, so arrhythmias are seen in almost all types of heart disease.

2. Disorders in the nervous and endocrine systems, and imbalances in water and electrolytes

The disorder of the regulation of the cardiac nervous and endocrine systems, the imbalance of the cardiac ion balance, etc.; the myocardial hypoxia mediated by hypoxemia and the regulation of systemic and cardiac acid-base balance caused by various reasons other than cardiac factors, etc., have the necessary basis for the ions and metabolism of arrhythmias, form the conditional factors of arrhythmias, and thus often induce the occurrence of arrhythmias.

3. Effects of medication

A variety of drugs can cause arrhythmias, such as non-potassium-sparing diuretics, digitalis, epinephrine, norepinephrine, isoproterenol, dopamine, dobutamine, amrinone, and milrinone. It is particularly noteworthy that various antiarrhythmic drugs prevent or terminate arrhythmias by either changing ion channels, stabilizing cell membranes, changing the heart's refractory period, or acting on the heart's receptors. However, antiarrhythmic drugs themselves also have arrhythmogenic effects and, if used improperly, can also mediate arrhythmias and even death.

4. Systemic or other systemic diseases such as nervous system diseases, endocrine system diseases, metabolic diseases, trauma, surgery, cardiac catheterization, etc. can cause arrhythmias.

5. Normal People

Sinus tachycardia or premature contractions may occur when you are emotionally excited, frightened, depressed, drinking alcohol, or drinking strong coffee. Healthy older people are more likely to develop arrhythmias than younger people. Generally speaking, arrhythmias will occur throughout a person's life.
