心房颤动的患者在电除颤后往往伴有心房收缩功能减退,血流动力学的改变使之易形成血栓,因此,正确地评价左房功能有助于指导除颤后抗凝治疗时间的长短。组织多普勒成像是近年开发并迅速发展起来的一项超声心动图新技术,可定量测量室壁运动速度、加速度、位移、应变及应变率,为心肌功能的研究提供了新的超声诊断方法。本文就心房超声应变和应变率成像在心房颤动抗凝、复发预测等方面的应用价值进行简要综述。
Patients with atrial fibrillation are often accompanied by atrial fibrillation after defibrillation, hemodynamic changes make it easy to form thrombus, therefore, a correct evaluation of left atrial function helps guide the length of anticoagulant therapy after defibrillation . Tissue Doppler imaging is a new echocardiography developed and rapidly developed in recent years. It can quantitatively measure wall motion velocity, acceleration, displacement, strain and strain rate, and provides a new method for ultrasonic diagnosis of myocardial function . In this paper, the clinical value of atrial ultrasound strain and strain rate imaging in the prediction of atrial fibrillation and recurrence is briefly reviewed.
