A case is presented of a man who had 5 hours of atrial fibrillation followed by spontaneous conversion and maintained sinus rhythm that persisted as shown by surface electrocardiography. Transesophageal echocardiography performed 24 hours after electrocardiographic conversion documented an atrial fibrillation pattern within the left atrial appendage, with a normal sinus Doppler pattern in the body of the left atrium. This apparent regional discrepancy in atrial function may partially explain the increased risk for "late" thromboembolism among patients with atrial fibrillation who appear to be successfully converted with sustained sinus rhythm.
本文报告一例男性患者，其房颤持续5小时后自行转复并维持窦性心律，体表心电图显示该心律持续存在。心电图转复后24小时进行的经食管超声心动图检查显示，左心耳内存在房颤模式，而左心房主体的窦性多普勒模式正常。心房功能的这种明显区域差异可能部分解释了房颤患者在看似成功转复为持续性窦性心律后发生“晚期”血栓栓塞风险增加的原因。
