摘　　要：４０例常规心电生理检查不能诱发的室上性心动过速（ＰＳＶＴ）患者，随机分为两组，分别在给予阿托品或自主神经阻滞（ＡＮＢ）后重复检查，结果ＡＮＢ组诱发成功率为６５％（１３例），与阿托品组的５５％（１１例）无显著性差异（Ｐ＝０３７２）。用药前后两组心电生理参数变化相似，提示两组ＰＳＶＴ诱发成功率增高的机理相同。Forty patients whose paroxysmal supraventricular tachycardia (PSVT) could not be provoked by conventional cardiac electrophysiologic test were randomly divided into two groups,and received repeated study after venous atropine injection and automatic nervous block(ANB) respectively.The results showes that provoked rate was 65%(13 cases)in ANB group and 55%(11 cases)in atrpoine group,there was no significant difference between two groups (p=0.372).The changes of cardiac electrophysiologic parameters were alike.It indicated that there are same mechanism of increased provoked rate in two groups.
