心律失常在心脏疾患时比较常见,临床上多借助心电图进行诊断。近年来通过超声心动图检查,发现之不同心律失常各自出现比较特异的波形,对诊断有一定帮助。本文报告一例心房扑动—心房纤颤—电复律转为窦性心律的心肌病患者在超声心动图上的一系列改变,并结合血流动力学的特点,讨论各种波形产生的机制及其临床意义。 Arrhythmia in heart disease is more common, more clinical diagnosis with ECG. In recent years through echocardiography, found that different arrhythmias appear more specific waveform, the diagnosis will be of some help. This article reports a series of echocardiographic changes in a patient with cardiomyopathy with atrial flutter-atrial fibrillation-electrical cardioversion converted to sinus rhythm. In addition, the mechanism of various waveforms and the characteristics of hemodynamics are discussed Its clinical significance.
