Diagnosis and Management of Idiopathic Ventricular Tachycardia

Idiopathic ventricular tachycardia (VT) refers to VT occurring in structurally normal hearts. It is commonly seen in young patients and typically has a benign course. Because the origin is typically focal and the heart is without scar, the 12-lead electrocardiogram is extremely useful for localizing the origin of idiopathic VT. Treatment options include reassurance, medical therapy, and catheter ablation. This review describes the clinical features, electrocardiogram recognition, and management of idiopathic monomorphic VT.
