67 test persons (15 healthy persons, 52 patients with coronary heart disease, of them 28 patients with and 24 patients without myocardial hypertrophy) were examined by means of a mapping ECG (69 leads) and the echocardiography. For every individual lead of the mapping ECG the mean values and simple scattering of the R and S potentials of 15 normal persons have been established. Of this we led the limit values for left heart and right heart hypertrophy for every individual lead. We are able to make evident that for the determination of a myocardial hypertrophy the principle of Sokolow's index can be transferred to R (max) and S (min) of the mapping ECG. A quantification of the myocardial hypertrophy by means of the R-potential summation method presupposes a correction of the normal potential decrease in the cardio-electric field. A regionally differently characterized myocardial hypertrophy can be recognized with the help of the mapping ECG. By means of an exercise-induced mapping ECG hypertrophy-caused repolarisation disturbances can highly significantly be demarcated (p less than 0.001) from ischaemia-caused ones. The difference mapping is suitable as mapping ECG documentation for a myocardial hypertrophy.
67名受试者（15名健康人，52名冠心病患者，其中28名有心肌肥厚，24名无心肌肥厚）接受了标测心电图（69导联）和超声心动图检查。对于标测心电图的每一个导联，已确定15名正常人R波和S波电位的平均值及简单离散度。据此得出了每个导联左心室和右心室肥厚的限值。我们能够证明，对于心肌肥厚的判定，索科洛夫指数的原理可应用于标测心电图的R（max）和S（min）。通过R波电位总和法对心肌肥厚进行量化，前提是校正心脏电场中正常电位的降低。借助标测心电图可识别出具有不同区域特征的心肌肥厚。通过运动诱发的标测心电图，可将肥厚引起的复极紊乱与缺血引起的复极紊乱高度显著地区分开来（p<0.001）。差值图适合作为心肌肥厚的标测心电图记录。
