Precordial maps of R, S and Q waves were performed in 43 children with congenital and acquired cardiac defects, with cardiomyopathies and also in 55 healthy children. Two subgroups with the left and right ventricular hypertrophies were separated basing on a standard electrocardiogram. Multilead electrocardiogram (M60--ecg) was recorded from 60 points of a chest wall. Obtained data indicate that a multilead electrocardiogram is useful for ventricular hypertrophy estimation in cardiac defects and cardiomyopathies. Of analyzed R, S and Q waves R wave is essentially important. Different localization and extent of a region of large R wave amplitudes was observed in children with cardiac defects and cardiomyopathies in comparison with healthy persons. Accessory precordial points for R wave registration (besides standard ones) with statistically significant larger R wave amplitude than in healthy children are: A9, A10, B9, B10 for left ventricular hypertrophy assessment and A1, A5, B2, C3, C4, C5, D3, D5, E3, E4, E5, F4 for right ventricular hypertrophy estimation.
对43例患有先天性和后天性心脏缺陷、心肌病的儿童以及55例健康儿童进行了R波、S波和Q波的心前区心电图测绘。根据标准心电图将患儿分为左心室肥厚和右心室肥厚两个亚组。从胸壁的60个点记录多导联心电图（M60-ecg）。获得的数据表明，多导联心电图有助于评估心脏缺陷和心肌病中的心室肥厚情况。在所分析的R波、S波和Q波中，R波尤为重要。与健康儿童相比，患有心脏缺陷和心肌病的儿童观察到R波振幅大的区域有不同的定位和范围。用于记录R波的辅助心前区点位（除标准点位外），其R波振幅在统计学上显著大于健康儿童，这些点位为：评估左心室肥厚时的A9、A10、B9、B10，以及评估右心室肥厚时的A1、A5、B2、C3、C4、C5、D3、D5、E3、E4、E5、F4。
