RELATION OF ECG ABNORMALITIES TO EVOLVING LEFT VENTRICULAR HYPERTROPHY IN HCM

肥厚型心肌病患者经常表现出 左心室壁厚度增加或甚至新发 儿童时期肥大的发展。 确定 心电图在反映左室变化中的作用 心室质量，连续12导联心电图和两个- 分析了38例先天性心脏病患儿的二维超声心动图， 肥厚型心肌病 这项研究的结果表明，儿童肥大 心肌病和左心室肥厚的进展表明， 在这段时间里，心电图几乎没有变化。 观察. 然而，心电图异常可能是 肥厚型心肌病的最初表现， 即使在左心室肥大被检测到之前， 超声心动图，从而提供了形态学的先进证据 随后会发生的变化。

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.
