The causes of frequent ventricular premature beats are exertion and various organic heart disease, etc. According to the causes, triggers and typing to determine the degree of harm, drugs and surgery can be taken for treatment. 1. Causes: frequent ventricular premature beats can be seen in cardiac organic lesions, such as ischemic cardiomyopathy, coronary artery disease and pulmonary heart disease, etc.; it can also be seen in non-cardiac organic lesions, such as overexertion, alcohol consumption and excessive anxiety. 2. Hazard: Among patients with frequent ventricular premature beats, those whose causes and triggers are non-organic heart disease will not have obvious or serious discomfort; however, some patients may suffer from malignant arrhythmia caused by frequent ventricular premature beats, such as ventricular tachycardia, ventricular fibrillation and other arrhythmias with high fatality rate; for the elderly with combined cerebrovascular disease, frequent ventricular premature beats may lead to serious complications, such as cerebral infarction. 3. Treatment: The principle of treatment for frequent ventricular premature beats is to first find out the cause or trigger, release the trigger, treat the cause, and then according to the electrocardiogram and other tests to determine whether it is a single source or multiple sources of premature ventricular beats, if it is a single source of premature ventricular beats, then consider radiofrequency ablation surgery; if it is a multiple source of premature ventricular beats, then consider the treatment of antiarrhythmic drugs such as metoprolol. Frequent ventricular premature beats require electrocardiograms and other tests to diagnose, combined with medical history to determine whether treatment is needed, patients should not self-medication, life or treatment, if any persistent or obvious discomfort, it is recommended that timely medical treatment to avoid ventricular fibrillation and other serious consequences.
