ABLATION OF IDIOPATHIC VENTRICULAR TACHYCARDIA


Komandoor S. Srivathsan, M.D., Mayo Clinic, Arizona, USA

Idiopathic ventricular tachycardia occurs when ventricular tachycardia occurs in the absence of detectable heart disease. Other than syncope they can cause cardiomyopathy if Premature Ventricular Contraction is frequent. Medications are partially effective but ablation when done carefully is effective over 90% of the time. Most of these arrhythmia is concentrated around the outflow tracts. Implantable cardiac defibrillator (ICD) is generally not indicated and successful ablation is curative.
