本文作者设计了一套新的食管电极系统,并研究了它在房性和室性快速性心律失常中电复律的疗效。方法共在105名病人中进行131次经食道心脏电复律,其中房颤109次,房扑16次,室上速2次,室速4次。所用的食管电极为4极、外径5～9mm。插入前先静脉给安定(2.5～20mg),电极插入深度为距门齿35～40cm。所有病人均记录经食管阻抗,而在104名病人中记录经胸阻抗。静脉麻醉后
The authors designed a new set of esophageal electrode systems and investigated its efficacy in cardioversion of atrial and ventricular tachyarrhythmia. Methods Totally 131 transesophageal cardiac cardioversion was performed in 105 patients, including atrial fibrillation 109 times, atrial flutter 16 times, supraventricular tachycardia 2 and ventricular tachycardia 4 times. Esophageal electrode used for the 4 pole, the outer diameter of 5 ~ 9mm. Prior to the insertion of intravenous diazepam (2.5 ~ 20mg), the electrode insertion depth of 35 ~ 40cm away from incisors. Transient esophageal impedance was recorded in all patients, while transthoracic impedance was recorded in 104 patients. After intravenous anesthesia
