摘　　要：目的探讨房室结折返性心动过速(AVNRT)慢快型体表心电图的诊断要点,为临床医师提供常规心电图(ECG)检查AVNRT的诊断依据.方法 1996年9月至2010年4月收住昆明医学院附属延安医院心内科经心内电生理检查诊断为AVNRT慢快型并成功行射频消融术(RFCA)的753例患者,将同一患者心动过速发作心电图和窦性心律心电图进行比较分析.结果心动过速发作心电图和窦性心律心电图比较:QRS波形态大小均相等或相似(100%),下壁导联出现假S波344例(45.7%),V1导联出现r’波589例(78.2%),假S波和r’波同时出现300例(39.8%).结论心动过速发作心电图下壁导联出现假S波和V1导联r’波对诊断AVNRT有较高的提示意义。Objective To reveal the characteristics of electrocardiography（ECG） in the diagnosis of AVNRT（fast-slowtype） and to provide basis for diagnosis of AVNRT by ECG.Methods Seven hundred and fifty-three patients of AVNRT were diagnosed by intracardiac electrophysiologic study,and successfully received radiofrequency ablation（RFCA） from September 1996 to April 2010.ECG of paroxysmal supraventricular tachycardia and sinus rhythm were compared and analyzed.Results By comparision,they all had the same and similar area in shape and size OF QRS complex（100%）.The existence of pseudo S waves in inferior leads was found in 344 cases,accounting for 45.7%,r＇ waves in V1 leads was found in 589 cases,accounting for 78.2%.The coexistence of pseudo S waves and r＇ waves was found in 300 cases,accounting for 39.8%.Conclusion The existence of pseudo S waves in inferior leads and r＇waves in V1 leads in electrocardiography of patients with tachycardias has potential value in diagnosis of AVNRT.
