【摘要】 为探讨ECG法阿托品试验重复性欠佳的原因及解决方法。6个月内，64例受检者在超微心电图（SMECG）连续观察及ECG间断记录下，进行阿托品试验2～5次。结果SMECG与ECG监测各次均为阴性24例。余40例SMECG监测均为阳性；ECG记录阳性23例，阴性8例，各次结果不完全一致9例。本观察发现，此差异的形成与ECG间断记录而漏记交界性自主心律及不能识别一些房性心律有关。结论：SMECG监测可改善阿托品试验的重复性，减少假阴性。更多还原

【Abstract】 To improve the accuracy of atropine test in clinical diagned, atropipe test was performed in 64 cases monitered by super micro- electrocardiograph (SMECG ) and ECG twice to five times in six months. 24 cases got negative result both in SMECG and ECG each time. 40 cases were positive in SMECG each time. Among the SMECG’s postive cases 23 cases were peitive, 8 cases negative and 9 cases with varied result at different time in ECG. The difference in results between SMECG and ECG were caused by ① ECG didn’t record continously, some junctional autonomous rhythms were missed. ② ECG cann’t distinguish some atrial rhythm from sinus rhythm. So SMECG may improve the accuracy of atropine test and reduce faise negative rate.更多还原
