To evaluated the recovery of atrial function following atrial fibrillation, we followed 66 patients with atrial fibrillation cardioverted to sinus rhythm. Over 3 months of follow-up we performed transmitral pulsed Doppler echocardiography. The results were evaluated according to the etiology, duration of atrial fibrillation, left atrial dimension and modality of cardioversion. We observed a significant increase in both peak A wave velocity and percent atrial contribution to total left ventricular filling after 1 month in hypertensive patients and after 3 months in ischemic patients. The recovery of atrial mechanical function was earlier in patients with recent atrial fibrillation (< 24 hours) and in patients with normal left atrium. These results may have implications in guiding the duration of anticoagulant therapy after cardioversion.
为评估心房颤动后心房功能的恢复情况，我们对66例已转复为窦性心律的心房颤动患者进行了随访。在3个月的随访期间，我们进行了经二尖瓣脉冲多普勒超声心动图检查。根据病因、心房颤动持续时间、左心房大小和转复方式对结果进行评估。我们观察到，高血压患者在1个月后、缺血性患者在3个月后，A波峰值速度和心房对左心室总充盈的贡献率均显著增加。近期心房颤动（<24小时）患者和左心房正常的患者心房机械功能恢复较早。这些结果可能对指导转复后抗凝治疗的持续时间有一定意义。
