子激综合征(W.P.W),易出现严重的甚至是致命的心律失常发作,是心脏猝死的主因之一,进一步探讨W.P.W的类型与并发心律失常的关系,以及寻求有效的根治方法,是有重要临床意义的。本文就二例A+B型予激征易并发室颤,经从腔内电生理检查及心外膜标测证实,最后用注射无水酒精破坏旁路传导的方法进行根治的W.P Sub-paroxysmal syndrome (WPW), prone to severe or even fatal arrhythmia, is one of the major causes of sudden cardiac death. It is important to further explore the relationship between the type of WPW and arrhythmia and the search for an effective cure Clinically meaningful. In this paper, two cases of A + B type of predisposition and easy to complicated by ventricular fibrillation, electrophysiological examination from the endocardium and epicardial mapping confirmed by the last injection of anhydrous alcohol to bypass the conduction method of radical W.P
