RELATION OF ECG ABNORMALITIES TO EVOLVING LEFT VENTRICULAR HYPERTROPHY IN HCM

肥厚型心肌病患者通常表现为实质性的 左室壁厚度增加，甚至重新开始 儿童期肥大的发展。要确定 心电图在反映左心功能改变中的作用 连续12导联心电图室壁质量和两个 本文对38例儿童心脏超声心动图进行了分析。 肥厚型心肌病。 这项研究的结果表明，肥厚症儿童 显示心肌病和进行性左室肥厚 病程中心电图变化不大。 观察。然而，心电图异常可能是 肥厚型心肌病的首发表现 甚至在左心室肥厚被检测到之前 超声心动图，从而提供了形态上的先行证据 随后将发生的变化。

Patients with hypertrophic cardiomyopathy often show substantial increase in left ventricular wall thickness or even de novo development of hypertrophy during childhood. To determine the utility of the electrocardiogram in reflecting such changes in left ventricular mass, serial 12-lead electrocardiograms and two- dimensional echocardiograms were analyzed in 38 children with hypertrophic cardiomyopathy. The results of this study show that children with hypertrophic cardiomyopathy and evolving left ventricular hypertrophy showed little change in the electrocardiogram during the period of observation. However, electrocardiographic abnormalities may be the initial manifestation of hypertrophic cardiomyopathy, appearing even before left ventricular hypertrophy is detectable by echocardiography, thus providing advance evidence of morphologic changes that will subsequently occur.
