esophageal lead

Sequence of retrograde P wave in V1 ( P-V1) and esophageal lead ( PE-) was observed by esophagus and V1 synchronization electrocardiogram.

同步记录食管与V1导联心电图，观察P波在V1（P-V1）及食管导联（P-E）的先后顺序。

It showed that on bipolar esophageal lead, P wave after electric pulse could be recorded clearly in 35% patients;

结果显示受检患者中35%能在双极食管导联中清晰记录到位于电脉冲波后的P波；

Results Sinus P wave recorded by bipolar esophageal lead consisted of right atrial potential and left atrial potential.

结果双极食管导联记录到的窦性P波由圆钝直立的右心房电位和尖锐高大的左心房电位组成。

Objective To investigate the method of recording right atrial potential by bipolar esophageal lead and its clinical significance.

目的探讨双极食管导联记录右心房电位的方法及其临床意义。
