[Ventricular fibrillation/tachycardia].
Ventricular fibrillation and rapid ventricular tachycardia called as pulseless tachycardia are both fetal and need immediate therapy to respore sinus rhythm. Sustained monomorphic ventricular tachycardia is also known to have a poor prognosis. Diagnosis of these arrhythmias should be followed by electrophysiologic study for risk stratification. The efficacy of the antiarrhythmic drug therapy is known to be limited. Catheter ablation can cure the arrhythmia but the success rate is limited: 50-70% in selected patients. Though symptomatic, ICD is the most reliable therapy so far. Antiarrhythmic drugs or catheter ablation should be tried as adjunctive therapy in fatal ventricular arrhythmias.
