Premature ventricular contractions are heart beats caused by premature impulses from ectopic pacing points and are the most common cardiac arrhythmia. Frequent ventricular premature beats should be treated with care, especially if they may evolve into serious heart rhythm disorders based on heart disease or may lead to angina pectoris and heart failure. Xinhua Wang, Department of Cardiology, Shanghai Renji Hospital If there is no organic heart disease and the number of premature beats is not large, treatment is not needed. If the number is relatively large, you can consider taking some medications. Furthermore, if the number of premature beats exceeds 10,000 throughout the day, some patients can also consider radiofrequency ablation surgery. In addition, do not smoke, do not drink alcohol, do not eat too much, and do not eat stimulating food. Pay attention to the combination of work and rest, and get enough sleep. Chronic patients whose premature beats do not increase after activity should participate in sports and cultural activities.
