To determine the feasibility and efficiency of terminating atrial flutter (AFL) and atrial fibrillation (AF) using synchronous low-energy shocks delivered through a novel transesophageal electric balloon electrode system.
By using a novel electric balloon electrode system, we attempted 91 transesophageal cardioversions in 52 patients, to treat 53 episodes of AFL and 38 episodes of AF.
Of the 40 patients of AFL that failed to respond to drug therapy, 37 (92.5%) were successfully countershocked to sinus rhythm by transesophageal cardioversion, with a mean energy of (22.70 +/- 4.50) J (20 - 30 J). Of the 19 patients in AF, transesophageal cardioversion was successful in 16 (84.2%) cases, requiring a mean delivered energy of (17.38 +/- 8.58) J (3 - 30 J). There were no complications such as heart block or ventricular fibrillation, and no evidence of esophageal injury.
Transesophageal cardioversion using an electric balloon electrode system is an effective and feasible method for the treatment of AFL and AF. It requires low energy and no anesthesia, leads to less trauma, and shows a high cardioversion success rate that may prove valuable in the management of tachyarrhythmias.
通过一种新型经食管电球囊电极系统施加同步低能量电击，确定终止心房扑动（AFL）和心房颤动（AF）的可行性和有效性。
使用一种新型电球囊电极系统，我们对52例患者尝试进行了91次经食管心脏复律，以治疗53次心房扑动发作和38次心房颤动发作。
在40例对药物治疗无反应的心房扑动患者中，37例（92.5%）通过经食管心脏复律成功转复为窦性心律，平均能量为（22.70±4.50）J（20 - 30 J）。在19例心房颤动患者中，经食管心脏复律16例（84.2%）成功，所需平均释放能量为（17.38±8.58）J（3 - 30 J）。未出现诸如心脏传导阻滞或心室颤动等并发症，也没有食管损伤的证据。
使用电球囊电极系统进行经食管心脏复律是治疗心房扑动和心房颤动的一种有效且可行的方法。它所需能量低且无需麻醉，创伤较小，心脏复律成功率高，可能在快速性心律失常的管理中具有重要价值。
