【摘要】 本文用ATP和异搏定终止24例FSVT,比较两药的有效性、电生理效应和副作用。结果显示:虽然西药主要作用都在房室结,但两药复律方式、电生理效应有差异;终止FSVT两药疗效相似(P>0.05),ATP复律快(P<0.05),而异搏定复律过程平稳且复律后心律失常发生率低(P<0.05)。更多还原

【Abstract】 The efficacy, electrophysiologic effects, and side effects of ATP and verapamil in the short-term management of PSVT were compared in 24 patients. The results showed that there were many differences in eleetrophysiologic mechanism between ATP and verapamil in the short-term management of PSVT although termination of PSVT by ATP and verapamil was related to a block in the atrioventrieular (AV) node in most of the patients. The overall efficacy of ATP was not significantly greater than that of verapamil in the termination of PSVT (P>0.05); however, ATP terminated PSVT more quickly than veraramil (F<0.05). The total incidence of transient AV node block and various cardiac supraventricular and ventricular arrhythmias was higher after termination of FSVT by ATP than verapamil (P<0.05).更多还原
