The risk of ventricular premature triplets depends on the severity of the patient’s primary disease. Ventricular premature triplets are frequent ventricular premature beats, which can occur in normal people, but are more likely to occur in patients with cardiac neurosis and organic heart disease. Emotional excitement, nervousness, fatigue, indigestion, excessive smoking, drinking alcohol or strong tea can cause attacks. Ventricular premature triplets due to physiological causes are usually not harmful, but may cause palpitations and discomfort. Ventricular premature triplets caused by coronary artery disease, cardiomyopathy and myocarditis are more dangerous to patients and may lead to serious heart failure and malignant arrhythmias, which need to be treated actively. The presence of ventricular premature triplets in these patients often indicates a poor prognosis and a risk of sudden death.
