Wolff-Parkinson-White Syndrome After Verapamil
We examined the electrophysiologic effects of verapamil in eight patients with the WolffParkinson-White syndrome. Verapamil shortened the antegrade effective refractory period of the accessory pathway in three patients and abbreviated the shortest cycle length with 1:1 conduction over the accessory pathway in two patients. More significantly, verapamil decreased the shortest RR interval between...

متن کاملCycle length alternation in supraventricular tachycardia after administration of verapamil.
Four patients are reported in whom alternation ofRR cycle length before reversion to sinus rhythm occurred during the administration of intravenous verapamil. In 2 of these 4 patients, alternation of cycle lengths was associated with a changing QRS morphology. It is suggested that one patient had a reciprocating tachycardia using dual AV nodal pathways. The alternating cycle lengths in response...
متن کاملImprovement in angiographic cerebral vasospasm after intra-arterial verapamil administration.
BACKGROUND AND PURPOSE Endovascular options for therapy for patients with vasospasm after SAH include angioplasty and intra-arterial vasodilator infusion. Preliminary studies of the effects of the calcium channel antagonist verapamil on angiographic vasospasm have yielded mixed and/or qualitative results. In this study, improvement in angiographic vasospasm after intra-arterial verapamil admini...
