Internal cardioversion was attempted in three patients with chronic atrial fibrillation, refractory to conventional external direct current shocks. Endocardiac shocks were delivered between the proximal electrode on a multipolar USCI pacing catheter and a back paddle. This is positioned with the tip proximal of the bundle of His, and the proximal ring electrode floating in the right atrium. Two patients were converted with 200 Joules, one needed 400 Joules. Two of our three patients were chronically maintained in sinus rhythm after the initial conversion, one had recurrence within 24 hours.
对三名慢性心房颤动患者尝试进行体内心脏复律，这些患者对传统的体外直流电电击无效。心内电击在多极USCI起搏导管上的近端电极和背部电极板之间进行。电极板放置在希氏束近端，近端环形电极漂浮在右心房。两名患者用200焦耳成功复律，一名患者需要400焦耳。在最初复律后，我们三名患者中有两名长期维持窦性心律，一名在24小时内复发。
