Alterations in ECG in hypertrophic cardiomyopathies (HCMP) have been described already earlier when the knowledge of HCMP was not so profound. The aim of this work was to analyse ECG findings in hypertrophic myelopathy and to determine their relation to morphological observations. 76 patients examined echocardiographically with catheterization were performed ECG recordings. Normal ECG had 3 patients (3.9%). In the rest of them electrocardiography confirmed left ventricular hypertrophy (63.2%), large R wave in V1(-3) (14.5%), diminishing of R wave in V1(-3) (28.9%), pathologic Q wave (23.7%), absence of "q" wave in V5,6 (48.8%), ST-T abnormalities (86.7%). Pathologic Q wave was found more often in patients with right ventricular hypertrophy, deep T waves (greater than 10 mm) currently occurred in apical form. It follows that the presence and the range of myocardial hypertrophy cannot be electrocardiographically recorded. Therefore the ECG is applied in great majority of patients only as a screening method.
在肥厚型心肌病（HCMP）中，心电图改变早在人们对HCMP的认识还不那么深入时就已被描述。这项工作的目的是分析肥厚型心肌病患者的心电图表现，并确定其与形态学观察结果的关系。对76例接受超声心动图检查并行心导管插入术的患者进行了心电图记录。心电图正常的有3例（3.9%）。其余患者中，心电图证实有左心室肥厚（63.2%）、V1（-3）导联R波高大（14.5%）、V1（-3）导联R波减小（28.9%）、病理性Q波（23.7%）、V5、6导联无“q”波（48.8%）、ST-T异常（86.7%）。病理性Q波在右心室肥厚患者中更常见，深T波（大于10mm）目前以心尖部形态出现。由此可见，心肌肥厚的存在和范围无法通过心电图记录。因此，心电图在绝大多数患者中仅作为一种筛查方法应用。
