临床常规导联体表心电图的P波有时很小,致使某些心律失常的诊断碰到困难。我们从1982年起进行经滤波双极食道心电图的方法学研究,旨在为心律失常的诊断和鉴别诊断提供突出P波的方法。经临床初步应用结果满意,现摘要报道如下。仪器设备食道电极使用国产JD-2720双极起 Clinical routine lead P wave surface ECG is sometimes small, resulting in the diagnosis of some arrhythmia encountered difficulties. We performed a methodological study of filtered bipolar esophagoscopy since 1982 to provide a method of highlighting P waves for the diagnosis and differential diagnosis of arrhythmia. The clinical preliminary results are satisfactory, the summary is reported below. Equipment Esophageal electrodes using domestic JD-2720 bipolar
