因为经胸部电复律仅有小量能量释放通过心脏,实际上是一个低效程序。作者创造了一种稳固的食管电极系统,并用此电极系统对房性心律失常进行直流电休克取得初步经验。食管电极系统由4个电极组成,在 PVC 管上装有铜丝线圈样金质电极板,其 PVC管内径为5～9mm。作者使用此食管电极系统从口腔至该系统尖部放置35～40cm,已成功地对5例患者进行了6次电复律,其中4例为心房纤颤,1例为反 Because only a small amount of energy is released through the heart via cardioversion, it is actually an inefficient procedure. The authors created a robust esophageal electrode system and obtained initial experience with this electrode system for atrial current arrhythmia by DC shock. Esophageal electrode system consists of 4 electrodes, with a copper wire coil-like gold electrode plate on the PVC pipe, the PVC pipe diameter of 5 ~ 9mm. The authors used this esophageal electrode system to place 35-40 cm from the oral cavity to the tip of the system, and five electrical cardioversion was successfully performed on five patients, four of whom were atrial fibrillation and one was anti
