摘要 目的:探讨体表心电图逆行P波特征在单旁路顺向型房室折返性心动过速(O-AVRT)的诊断价值。方法:100例经心内电生理诊断并成功消融的O-AVRT患者回顾性分析其体表心电图逆行P波特征。①O-AVRT时体表心电图RP-的时限。②O-LAVRT时体表心电图中P-在不同导联中的极性。结果;①100例O-AVRT中RP^->70毫秒,RP->1/2RR为OAVRT。②左侧旁路67例,其中59例PI^-(-)(88%),P_(Vl)^-(+)67例(100%)。右侧33例中PI^-(+)26例(78.8%)P_(Vl)^-(-/±)30例(90.9%)。 Objective:To reseach the diagnosis value of the retrograde P wave features of electrocardiography in single bypass orthodomic atrioventrieular reentrant tachycardia ( O - AVRT). Methods :To retrospective analysis the retrograde P wave features of electrocardiography in the 100 subjects O - AVRT that had been diagnosis by cardiac electrophysiology and had been successful radiofrequency ablation. ①The time of RP - in electrocardiography while O - AVRT. ② The P -wave polarity in different leads of electrocardiography while O - LAVRT. Resuhs:①there were O - AVRT when RP- 〉 70 毫秒, RP^- 〉 1/2RR in 100 subjects O - AVRT. ②There were 59 subjects( 88% ) PI^- ( - ) ,67 subjects ( 100% ) PV1^ - ( + ) in 67 subjects of left - bypass. There were 26 sbujects (78.8%)PI^- ( + ) ,30 subjects (90.9%) PV1^ ( -/± ) in 33 subjects of fight - bypass.
