UNLABELLED
Internal Cardioversion.
INTRODUCTION
This report describes the electrical conversion of atrial fibrillation in two morbidly obese patients refractory to external cardioversion at 360 J.
METHODS AND RESULTS
The two patients were lightly sedated and underwent placement of decapolar catheters in the coronary sinus and right atrial appendage. All ten electrodes of each decapolar catheter were electrically coupled, and defibrillation was attempted at successively increasing levels using a biphasic decaying exponential waveform generated by an external defibrillator. Both patients were returned to normal sinus rhythm using < or = 10 J without complication.
CONCLUSION
Internal cardioversion is effective in restoration of sinus rhythm in some patients refractory to conventional forms of therapy.

引言
本报告描述了两名病态肥胖患者的心房颤动电复律情况，这两名患者对360焦耳的体外心脏复律无效。
方法与结果
两名患者轻度镇静，在冠状窦和右心耳放置十极导管。每个十极导管的所有十个电极均电连接，使用外部除颤器产生的双相衰减指数波形，以逐渐增加的能量水平尝试除颤。两名患者均使用≤10焦耳恢复窦性心律，无并发症。
结论
体内心脏复律对一些传统治疗无效的患者恢复窦性心律有效。
