Sixteen patients in sinus rhythm at baseline undergoing implantable cardioverter-defibrillator implantation were monitored with transesophageal echocardiography both before and after direct current cardioversion with currents of 15 to 20 J, for any direct current induced atrial dysfunction. We found no change in the indexes of atrial function or appearance of spontaneous echo contrast in the immediate postshock period by intraoperative transesophageal echocardiography.
16例基线时处于窦性心律且正在接受植入式心脏复律除颤器植入术的患者，在15至20焦耳电流直流电复律前后均接受经食管超声心动图监测，以观察任何直流电诱发的心房功能障碍。通过术中经食管超声心动图，我们发现在电击后即刻心房功能指标无变化，也未出现自发显影。
