Whether ventricular premature beats are serious depends on the cause of the ventricular premature beats. From a medical perspective, physiological ventricular premature beats are generally not serious and do not greatly affect health or endanger life. Physiological ventricular premature beats are often related to emotional stress, staying up late, and poor lifestyle habits such as drinking strong tea or coffee. Pathological ventricular premature beats, on the other hand, are often more serious, such as those caused by cardiomyopathy. These ventricular premature beats can potentially trigger ventricular tachycardia or ventricular fibrillation, seriously endangering the patient's life. Pathological ventricular premature beats require active interventional treatment to prevent the premature beats from worsening and causing unexpected events.
