Frequent ventricular premature beats may lead to sudden death. Frequent ventricular premature beats may induce ventricular tachycardia, ventricular fibrillation, which may lead to sudden cardiac arrest. Frequent ventricular premature beats may induce ventricular fibrillation. Once ventricular fibrillation occurs, the ejection function of the heart will be severely impaired, leading to a serious lack of blood supply to the brain and causing cardiogenic shock, which can lead to life-threatening conditions. Ventricular fibrillation is a lethal arrhythmia, and if it is not resuscitated in a timely manner, the electrical activity of the heart usually disappears rapidly within a few minutes. Patients with frequent ventricular premature beats should seek prompt medical attention and take active measures to control the arrhythmia by treating the primary cause and the premature beats themselves.
