[Idiopathic ventricular tachycardia: clinical characteristics and management].

Outflow tract ventricular tachycardia (VT) is the most common form of idiopathic VT in clinical practice. The correct differential diagnosis with VTs caused by structural heart diseases (particularly arrhythmogenic right ventricular cardiomyopathy) is extremely challenging for the cardiologist. When correctly diagnosed, outflow tract VTs have a favorable prognosis in the majority of patients. At present, technical advancements and improved clinical experience in transcatheter ablation procedures may offer a definite therapy to an increasing number of patients with an acceptable complication rate.
