Arrhythmia? What's the cause?

Arrhythmia can be caused by structural abnormalities of the heart, conduction system problems, electrolyte disorders, drug factors, factors other than the heart, autonomic nervous dysfunction, and other factors. There are many causes of arrhythmia. The following are some common causes: 1. Structural abnormalities of the heart: Structural abnormalities of the heart, such as atria, ventricular septal defects, cardiomyopathy, etc., may lead to arrhythmia. 2. Problems in the cardiac conduction system: Problems in the cardiac conduction system, such as the sinus node, atrioventricular node, His bundle, etc., may lead to arrhythmia. 3. Electrolyte disorders: Blood potassium, calcium, magnesium and other electrolyte disorders, may affect the normal electrophysiological activities of the heart, leading to arrhythmia. 4. Drug factors: Some drugs, such as antiarrhythmic drugs, antidepressants, antibiotics, etc., may lead to arrhythmia. 5. Factors other than the heart: Some factors other than the heart, such as hypoxia, acidosis, hypoglycemia, fever, etc., may affect the normal function of the heart and lead to arrhythmia. 6. Autonomic nervous dysfunction: autonomic nervous dysfunction, such as imbalance between sympathetic and parasympathetic nerves, may lead to arrhythmia. 7. Other factors: Such as exercise, emotional excitement, smoking, drinking, etc., may also lead to arrhythmia. It should be noted that the cause of arrhythmia may be a single, may also be the result of a combination of factors. For patients with arrhythmia, detailed examination is needed to determine the specific cause and take appropriate treatment measures. At the same time, for some serious arrhythmia, such as ventricular tachycardia, ventricular fibrillation, etc., may require cardioversion or implantable defibrillator treatment. In short, arrhythmia is a common disease, if the symptoms of arrhythmia, should be promptly sought medical attention, detailed examination and treatment.
