心房颤动最常见的心律失常,发病率1%~2%,>65岁的人群中约6%会因此受到影响.除卒中、心力衰竭和认知功能障碍等后果外,高达近90%的心房颤动患者有轻微临床症状.在心房颤动患者的管理中,管理目标包括脑卒中预防和心律失常管理(心率和节律控制),当患者有明显的症状时,往往选择节律控制.在持续性心房颤动中,直流电复律法(DCCV)旨在恢复窦性心律(SR).心房颤动与电重构和结构重构有关,包括左右心房纤维化和扩大.左心房越大,心房颤动复发的风险越高.左心房内径、左心房面积、左心房容积已经被证实可以预测心房颤动复律后的复发.右心房面积、右心房内径及相关体表面积关于心房颤动复发的预测价值仅在1项研究中被提及.目前,左心房容积指数在预测心房颤动复发方面是一个重要的参数.但将来也许会兼顾左右心房在心房颤动复发方面的影响,.

Atrial fibrillation (AF) is epidemic. It is the most common arrhythmia and occurs in approximately 1%-2% of the general population, affecting 6% of those older than the age of 65 years. In addition to much-feared consequences of stroke, heart failure, and cognitive dysfunction, up to nearly 90% of the patients with AF are symptomatic. In the management of AF patients, the goals include stroke prevention and arrhythmia management (rate vs. rhythm control). Rhythm control is often selected when patients have significant symptom burden. Direct current cardioversion (DCCV) aims to restore sinus rhythm (SR) in persistent AF. AF is correlated with electrical and structural remodelling, including fibrosis and enlargement of the left and right atrium. The larger the left atrium, the higher the risk for recurrence of AF. Increased left atrial (LA) diameter (LAd), LA area, and LA volume have been confirmed to predict recurrence of AF after cardioversion. The predictive value of right atrial (RA) area and diameter, indexed to body surface area, for such prediction was assessed only in 1 study. Currently, the left atrial volume index is an important parameter in predicting the recurrence of atrial fibrillation. In the future, we may have a balance between the left and right atrium in the recurrence of atrial fibrillation.
