| 摘 要： | 为确定食管定向弯曲电极导管（自制导管）在食管内行心脏起搏、心室除颤及监护的效果和安全性，用自制导管定向弯位（甲）与定向直位（乙）及国产１０Ｆ双极导管（丙）对１３只犬进行心房起搏效果对照观察。结果表明：起搏阈值甲、乙、丙分别为１２．６±０．３，１７．４±０．６．３０．２±１．６Ｖ，Ｐ＜０．０１；起搏夺获率甲、乙、丙分别为１００％、５３．５８％、１８．１８％，Ｐ＜０．０１．对食管进行组织学检查，起搏安全值脉宽为５ｍｓ、电压≤７０Ｖ、频率２００～２２０ｐｐｍ、连续起搏时间≤１８０ｍｉｎ；极限值的脉宽、频率同上，电压＝８０Ｖ，连续起搏时间＝９０ｍｉｎ。除颤安全值电能≤２００Ｊ，总电能≤６００Ｊ；电烧伤值电能达３００Ｊ，总电能达１４００～１５００Ｊ。本研究为心脏有效的复苏提供一种实验依据。

| Abstract: | The purpose of this study was to determine the safety and efficacy of transesophageal cardiac pacing and countershock in thirteen dogs .using a directional crook electrode,The efficacy of atrial pacing was compared among three different methods -method A,directional crook placed I method B, directional straight placed ; method C,10F bipolar catheter. The thresholds of pacing were AB>C(P<0. 01)。Esophageal hibtology exarnination showed that the safety values of paci11g were pulse duration 5 ms,voltage≤70 V,fre-quency 200～220 ppm,continuous pacing≤180 min;that the limited values of pacing were pulse duration 5 ms,voItage=80V, frequency 200～220 ppm,continuous pacing 90 min; that the safety values of countershock were countershock≤200J,total countershock≤600J;that the electric injuries values of countershock were 300J,total countershock increased 1 400～1500J. |
