In the clinical setting of heart failure, combined use of M-mode and 2D echocardiography is a useful tool for the differentiation of cardiomegalies of an unknown cause. In combination with careful clinical examination echocardiography allows differentiation between pericardial effusion, congenital or acquired valvular heart disease, or cardiomyopathy as the underlying cause of heart failure. M-mode echocardiographic parameters relating to left ventricular dimensional change can be helpful in the quantitative evaluation of left ventricular function, especially when no abnormal segmental wall motion is present. However, due to the poor reproducibility of the echo parameters, this method is only of limited usefulness for follow-up studies or for the evaluation of the effect of drug interventions. In the evaluation of left ventricular performance during dynamic exercise, currently used echocardiographic techniques have not proved practical due to technical limitations.
在心力衰竭的临床环境中,M型和二维超声心动图联合使用是鉴别不明原因心脏扩大的有用工具。结合仔细的临床检查,超声心动图能够区分心包积液、先天性或后天性瓣膜性心脏病,或作为心力衰竭潜在病因的心肌病。与左心室尺寸变化相关的M型超声心动图参数有助于左心室功能的定量评估,特别是在没有节段性室壁运动异常的情况下。然而,由于超声参数的可重复性较差,该方法在随访研究或药物干预效果评估中的作用有限。在动态运动期间评估左心室功能时,由于技术限制,目前使用的超声心动图技术尚未被证明具有实用性。
