Transesophageal cardioversion was applied in 277 patients 296 times for arrest of cardiac arrhythmia. Paroxysmal fibrillation and flutter of the atria, and paroxysmal tachycardia were arrested in all cases, chronic atrial fibrillation in 92.4% and chronic irregular atrial flutter in 94.1% of cases. In the group of patients where transthoracic cardioversion at a voltage of 7 kV proved ineffective, the sinus rhythm was restored in 76.5% of cases with atrial fibrillation and 84.2% of cases with irregular atrial flutter when one of the electrodes was introduced into the esophagus. The mean defibrillating voltage in transesophageal cardioversion for chronic atrial fibrillation was by 53.8% lower than that in transthoracic cardioversion. The design of the esophageal electrode proposed provides for the continous recording of the ECG in the esophageal lead for the purpose of determining the optimum position of the electrode and identifying the character of disorders in the cardiac rhythm more precisely.
277例患者接受了296次经食管心脏复律以终止心律失常。所有病例的阵发性心房颤动和扑动以及阵发性心动过速均得以终止，慢性心房颤动患者中92.4%得以终止，慢性不规则心房扑动患者中94.1%得以终止。在经胸7 kV电压心脏复律无效的患者组中，当将一个电极插入食管时，心房颤动患者中有76.5%、不规则心房扑动患者中有84.2%恢复了窦性心律。慢性心房颤动经食管心脏复律的平均除颤电压比经胸心脏复律低53.8%。所提出的食管电极设计可用于连续记录食管导联心电图，以确定电极的最佳位置并更精确地识别心律失常的特征。
