Idiopathic verapamil-sensitive left ventricular tachycardia (VT) has characteristic QRS configurations during VT: right bundle-branch block with either left axis or right axis (less common) deviation. QRS duration is relatively narrow (0.13-0.16 s) and frequently endocardial activation prior to QRS is recorded during VT, which is the basis of its being called fascicular tachycardia. The mechanism is probably reentry, but the nature of the slow conduction necessary for the occurrence of reentry is quite different from that of other sustained monomorphic VT associated with structural heart disease. Chronic oral verapamil therapy is the drug of choice for alleviation of symptoms. Long-term prognosis is good.
