We aimed to identify predictors of atrial fibrillation recurrence after conversion to sinus rhythm.
MATERIAL/METHODS: We included 100 patients with a history of documented atrial fibrillation in the last 12 months that were assessed by transthoracic echocardiography, 12-lead electrocardiogram and signal averaged electrocardiogram of the P wave. Follow-up was 7.3 ± 2.2 months.
Atrial fibrillation recurrence was documented in 27 patients. It was more frequent in patients with longer duration of previous atrial fibrillation episode, with increased left atrium size and left ventricular mass, and it was correlated with the filtered P wave duration and Integral of the P wave.
Signal averaged ECG of the P wave, left atrium size and left ventricular mass determined by echocardiography could be helpful in predicting the risk of atrial fibrillation recurrence after conversion.
我们旨在确定转复为窦性心律后房颤复发的预测因素。
材料/方法:我们纳入了100例在过去12个月有房颤记录史的患者,这些患者接受了经胸超声心动图、12导联心电图和P波信号平均心电图评估。随访时间为7.3±2.2个月。
27例患者记录到房颤复发。在既往房颤发作持续时间较长、左心房大小和左心室质量增加的患者中更常见,并且与滤波后的P波持续时间和P波积分相关。
超声心动图测定的P波信号平均心电图、左心房大小和左心室质量有助于预测转复后房颤复发的风险。
