The hazards of ventricular premature beats can be mainly divided into the following aspects:

First, if a healthy person experiences ventricular premature beats, it can cause symptoms such as chest tightness, palpitations, fatigue, and dizziness. If these symptoms are quite noticeable, they often affect the patient's work and life, and at night, they can also impact sleep, leading to sleep deprivation;

Second, if the patient has severe structural heart disease, frequent ventricular premature beats can induce angina attacks in patients with coronary artery disease, and can lead to worsening of heart failure in patients suffering from heart failure;

Third, some malignant ventricular premature beats can also induce severe rapid malignant arrhythmias, such as sustained ventricular tachycardia and ventricular fibrillation, leading to sudden cardiac arrest and sudden cardiac death.
