Introduction
In general, frequent premature beats of the heart may be caused by psychological factors, unhealthy lifestyle habits, myocarditis, cardiomyopathy, coronary atherosclerotic heart disease, and other conditions. It is recommended to seek medical attention promptly and follow the guidance of a physician for treatment. In daily life, one should pay attention to moderate exercise to strengthen physical health, maintain a balanced diet and avoid overeating, and undergo regular physical examinations to detect and treat underlying diseases in a timely manner.
Generally, frequent cardiac premature beats may be caused by mental factors, unhealthy lifestyle habits, myocarditis, cardiomyopathy, or coronary atherosclerotic heart disease. It is recommended to seek timely medical advice and undergo treatment under a doctor's guidance. Detailed analysis is as follows:
1. Mental Factors
During prolonged periods of mental stress, anxiety, excessive pressure, or emotional excitement, the body's sympathetic nervous system becomes stimulated and releases hormones such as norepinephrine. These hormones can affect the heart's electrophysiological activity, causing abnormal automaticity of the cardiac pacemaker, thereby triggering frequent premature beats. It is recommended to maintain emotional stability, relax the body and mind through meditation, yoga, and other methods, maintain regular作息 (作息 here likely means作息 habits or routines), and avoid staying up late.
2. Unhealthy Lifestyle Habits
Heavy smoking, alcohol consumption, and drinking coffee or strong tea can stimulate the heart. Substances such as nicotine, alcohol, and caffeine may interfere with the heart's normal electrical conduction, altering the excitability of the cardiac pacemaker and causing frequent premature beats. In daily life, smoking should be quit and alcohol consumption limited, with reduced intake of coffee and strong tea to maintain a healthy lifestyle.
3. Myocarditis
Myocarditis is often caused by viral infections, such as Coxsackievirus or influenza virus. The virus invades the myocardium, causing damage to myocardial cells and inflammatory reactions, which subsequently affect the heart's electrical conduction system, leading to frequent premature beats. Symptoms may include fever, fatigue, and muscle pain. Patients should follow medical advice to take medications such as Coenzyme Q10 capsules, vitamin C tablets, and Creatine phosphate sodium for injection.
4. Cardiomyopathy
Cardiomyopathy may be caused by genetic factors, infections, or toxic effects. Myocardial cells gradually undergo degeneration, necrosis, and fibrosis, resulting in cardiac enlargement and decreased myocardial contractility, causing disordered cardiac electrical activity and leading to frequent premature beats. Symptoms such as dyspnea, fatigue, and edema may also appear. Patients can take medications such as metoprolol sustained-release tablets, captopril tablets, and spironolactone tablets under a doctor's guidance.
5. Coronary Atherosclerotic Heart Disease
Coronary atherosclerotic heart disease mainly results from coronary artery atherosclerosis causing vascular narrowing or occlusion, leading to myocardial ischemia and hypoxia, which affects normal cardiac electrophysiology and triggers frequent premature beats. Symptoms such as episodic chest pain,闷痛 (dull pain), or tightness may also occur. Patients can take medications such as aspirin enteric-coated tablets, atorvastatin calcium tablets, and nitroglycerin tablets according to a doctor's recommendations.
In daily life, attention should be paid to moderate exercise to enhance physical fitness, maintaining a balanced diet and avoiding overeating, as well as undergoing regular physical examinations to detect and treat underlying diseases promptly.
