摘　　要：目的:观察在对窄QRS波心动过速鉴别诊断方面,头胸导联心电图是否具有与常规导联心电图一样的价值。方法:对72例患者发生窄QRS波心动过速时,同步记录常规导联及头胸导联心电图各1份。先后由两位资深电生理医师分析作出心动过速机制的诊断,再由观察者将两位医生分析两种体表心电图的结果与心内电生理检查结果相对照,计算出两种体表心电图诊断的准确率,并作χ2检验。结果:72例患者常规导联心电图的诊断准确率分别是83.3%(60/72)和80.6%(58/72),头胸导联心电图的准确率分别是90.3%(65/72)和86.1%(62/72)。窄QRS波心动过速机制的总体准确率,头胸导联心电图(88.2%)虽高于常规导联心电图(81.9%),但无统计学上的差异。结论:在对窄QRS波心动过速的鉴别诊断方面,头胸导联心电图与常规心电图一样都具有较高的准确率。Objective:To observe whether there was difference between the head-chest lead electrocardiogram(HCECG)and the routine lead electrocardiogram(RLECG)in differentiation of narrow QRS complex tachycardias.Methods:HCECGs and RLECGs were recorded simultaneously when the narrow QRS complex tachycardias occurred.And each HCECG and RLECG was analyzed by 2 senior physicians of clinical electrophysiology.Then the results of the HCECGs and RLECGs were compared with those ones of intracardiac electrophysiology to get th...
