本文首次报道了特发性室性房颤患者对心得安、维拉帕米、异丙肾上腺素、普鲁卡因胺、双双酰胺和心房起搏的J波反应。此前已有报道，1例日本男性Brugada综合征患者在多导联中表现出与本病例相似的明显J波。5然而，我们的病例与Brugada综合征不同，因为通过输注钠通道阻滞剂（包括普鲁卡因胺和二丙酰胺），v1至v3导联没有引起J点或ST点升高。J波的突出和由此产生的VF依赖于心动过缓。西洛他唑可消除J波和VF。
DiscussionThis is the first report of a patient with idiopathic VF in whom the response of J waves to propranolol, verapamil, isoproterenol, procainamide, disopyramide, and atrial pacing could be evaluated. A Japanese male patient with Brugada syndrome, who showed a prominent J wave in many leads similar to our case, has been previously reported. 5 However, our case is distinguished from Brugada syndrome, as no J point or ST elevation was induced in leads V 1 through V 3 by infusion of sodium channel blockers, including procainamide and disopyramide. Prominence of the J wave and resultant VF were bradycardia dependent. The J wave and VF was eliminated by cilostazol.
