我们采用心内、心表和食管记录SNE的方法,以食管内记录为主,重点观察了在其它条件不变时,U波辨认及其对SNE记录的影响,认为U波本身也可以形成类似窦房结电位的图形。现总结如下,供同道们参考。材料和方法一、健康犬6只,雌雄、体重不拘,右侧第4肋间开胸、暴露心脏,将40极心表电极放置于上腔静脉和右心房交界处,作心表 We use intracardiac, epicardial and esophageal records of SNE methods, mainly in the esophageal record, focusing on observed under the other conditions remain unchanged, U-wave identification and its impact on SNE records that the U wave itself can form a similar The pattern of sinus node potential. Now summarized below, for fellow reference. Materials and methods First, the healthy dogs 6, male and female, weight, the right intercostal thoracotomy, exposed the heart, the 40 very polar table electrode placed in the superior vena cava and right atrium at the junction for the heart
