Echocardiography plays a longstanding and vital role in the management of atrial fibrillation (AF). Advances in 2D imaging, Doppler echocardiography and strain imaging have all contributed to major progress in AF treatment. Echocardiographically measured left atrial (LA) volume is a powerful predictor of maintenance of sinus rhythm following cardioversion as well as risk of thrombus formation and thromboembolism. Doppler derived parameters of atrial mechanical function including atrial ejection force provide related prognostic information. Transesophageal echocardiocardiograpy (TEE) guided cardioversion of AF allows for rapid conversion to sinus rhythm without prolonged oral anticoagulation, and TEE serves as a useful tool during catheter ablation of AF and atrial flutter. Newer measures derived from speckle tracking offer great promise in further improving the care of patients with AF.
超声心动图在心房颤动（AF）的管理中一直发挥着至关重要的作用。二维成像、多普勒超声心动图和应变成像技术的进步都推动了房颤治疗取得重大进展。超声心动图测量的左心房（LA）容积是预测复律后窦性心律维持以及血栓形成和血栓栓塞风险的有力指标。多普勒得出的心房机械功能参数，包括心房射血力，可提供相关的预后信息。经食管超声心动图（TEE）引导下的房颤复律可实现快速转为窦性心律，而无需长期口服抗凝药，并且TEE在房颤和心房扑动的导管消融过程中是一种有用的工具。基于斑点追踪得出的更新测量方法在进一步改善房颤患者的护理方面前景广阔。
