The aim of this study was to determine if kinetocardiography can detect regional abnormalities of left ventricular kinetics, as occurs in coronary patients. Kinetocardiogram, M-mode and two-dimensional echocardiograms were recorded in 33 subjects (mean age 63, range 29-75 years), who previously had a myocardial infarction. On two dimensional echocardiograms, long axis, short axis, apical 4-chamber and apical 2-chamber projections were studied. Regional contractile abnormalities were rated as hypokinesis, akinesis, dyskinesis and aneurysm. In 6 subjects two dimensional echocardiogram was normal, in 5 it showed hypokinesis with left ventricular normal dimension or dilatation, and in the remaining 22 patients various regional kinetic abnormalities were observed. The kinetocardiogram showed paradoxical systolic movements in all patients with ventricular dyssynergy and was normal in all patients with normal ventricular kinetics, with or without left ventricular dilatation and global hypokinesis. There were no correspondences between echocardiography and kinetocardiography, regarding sites and amount of abnormalities. Kinetocardiography can thus noninvasively detect qualitative left ventricular kinetics abnormalities, in patients with myocardial infarction.
本研究的目的是确定心动图能否检测出如冠心病患者中出现的左心室动力学局部异常。对33名曾患心肌梗死的受试者（平均年龄63岁，范围29 - 75岁）记录了心动图、M型和二维超声心动图。在二维超声心动图上，研究了长轴、短轴、心尖四腔和心尖两腔投影。局部收缩异常分为运动减弱、运动不能、运动障碍和室壁瘤。6名受试者二维超声心动图正常，5名显示运动减弱伴左心室尺寸正常或扩大，其余22名患者观察到各种局部动力学异常。心动图显示所有心室协同失调的患者均出现矛盾性收缩运动，而所有心室动力学正常的患者，无论有无左心室扩大和整体运动减弱，心动图均正常。在异常部位和程度方面，超声心动图与心动图之间没有对应关系。因此，心动图可以无创地检测心肌梗死患者左心室动力学的定性异常。
