Two dimensional echocardiography, because of its wide field of view, has been shown to be superior to the M mode approach for ultrasonic evaluation of the left ventricle. The use of this technique for determination of ventricular volume estimates and detection of asynergy has been promising but is limited by compromised image quality found in many patients with ischemic heart disease. Because it supplies cross-sectional information about the ventricular chamber and wall thickness simultaneously, this new technique lends itself to the anatomic localization of changes in regional performance that accompany ischemic heart disease. It allows simultaneous study of regional dynamic changes in chamber circumference, wall thickness and motion characteristics that give practical information on coronary artery disease and acute myocardial infarction.
二维超声心动图由于其视野广阔，已被证明在超声评估左心室方面优于M型方法。使用该技术测定心室容积估计值和检测协同失调具有前景，但受到许多缺血性心脏病患者图像质量受损的限制。由于它能同时提供心室腔和室壁厚度的横截面信息，这项新技术有助于对伴随缺血性心脏病的局部功能改变进行解剖定位。它允许同时研究腔周径、室壁厚度和运动特征的局部动态变化，从而提供有关冠状动脉疾病和急性心肌梗死的实用信息。
