Premature ventricular contractions are a common symptom of many diseases. Common organic causes include hypertension, coronary artery disease, cardiomyopathy, cardiac insufficiency, hyperthyroidism, electrolyte disorders, as well as functional causes such as overexertion, mental stress, smoking and alcohol consumption. Once the symptoms appear, you should go to the hospital for a systematic examination to clarify the cause in order to properly develop a treatment plan. Doctors usually arrange several basic tests, electrocardiogram or ambulatory electrocardiogram, cardiac ultrasound, blood tests, and cardiac function measurement. Treatment is divided into etiological treatment and symptomatic treatment to control premature beats. The etiological treatment is to control hypertension, improve myocardial ischemia, treat hyperthyroidism, correct electrolyte disorders such as low potassium, avoid exertional agitation and control heart failure. Symptomatic medications for premature beats include mexiletine, amiodarone, and cardioplegia, the dosage of which is determined by the doctor according to the patient’s specific condition and the results are followed up. Currently, myocardial nutrients, such as coenzyme and fructose, are also recommended. Some herbal medicines also have good efficacy, such as Zhenyuan and Yixin Fuxin. Patients with ineffective treatment can consider radiofrequency ablation for premature beats, which is an interventional cardiac catheterization treatment with high cost and high recurrence rate, so it is not the first-line treatment of choice, but only for those with frequent premature beats with ventricular tachycardia for whom drugs are ineffective.
