Overview

Premature ventricular contractions can occur in a healthy person of any age, however they are more common in patients with underlying heart disease such as ischemic heart disease and structural heart disease. Patients on tricyclic antidepressant are at risk of having PVCs.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
