Echocardiography is a valuable technique for the diagnosis and serial follow-up of patients with impaired cardiac function. It is subject to certain limitations due to the assumptions inherent in deriving ventricular volume from a one-dimensional measurement and must be interpreted with caution in cases of suspected regional abnormalities of contraction. Given these caveats, echocardiography is valuable in the quantitative assessment of cardiac size and the level of compensation in patients with primary myocardial disease, valvular heart disease, and left ventricular hypertrophy. It can detect abnormal contraction in some patients with ischemic heart disease and provides an accurate method to serially follow changes produced as a result of drug or surgical therapy. Finally, two-dimensional techniques promise to provide a new perspective on the evaluation of patients with regional wall motion abnormalities.
超声心动图是诊断和连续随访心功能受损患者的一项重要技术。由于从一维测量推导心室容积存在内在假设，该技术存在一定局限性，在怀疑有局部收缩异常的情况下必须谨慎解读。鉴于这些注意事项，超声心动图在定量评估原发性心肌病、心脏瓣膜病和左心室肥厚患者的心脏大小及代偿水平方面很有价值。它能检测出一些缺血性心脏病患者的异常收缩，并提供一种准确方法来连续追踪药物或手术治疗所产生的变化。最后，二维技术有望为评估局部室壁运动异常患者提供新的视角。
