冠心病是老年常见病,随着电子技术的不断发展,近年来各种无创伤性心血管检查诊断方法已广泛应用于临床。通过心血管造影和血液动力学直接监测对比,早已证实从体表测得的各种无创伤检查如心电、心音、超声心动图,心机械图等可以反应心脏血液动力学变化,从而为冠心病提供一定的诊断指标。本文应用心电、超声、心阻抗图对100例冠心病进行探讨。
Coronary heart disease is a common disease in the elderly. With the continuous development of electronic technology, various noninvasive cardiovascular diagnostic methods have been widely used in clinical practice in recent years. Direct contrast by cardiovascular angiography and hemodynamics has long proved that various noninvasive tests such as ECG, heart sound, echocardiography, cardiograph and so on can reflect the changes of cardiac hemodynamics, Heart disease to provide some diagnostic indicators. In this paper, ECG, ultrasound, cardiac impedance map of 100 cases of coronary heart disease to explore.
