title: [Information value of different leads for precordial mapping in left ventricular hypertrophy].
abstract: New electrocardiographic criteria of left-ventricular hypertrophy (LVH) have been identified at automated analysis of ECG-35 cartograms (71 normal and 88 LVH recordings). Simultaneous application of 2 sums of S and R amplitudes (S32 + R14 and S30 + R19) obtained from the leads other than Wilsonian chest leads enabled a 1.5-fold increase in the sensitivity of electrocardiographic LVH diagnosis, as compared to the Sokolov-Lyon criteria, without loss of specificity. The use of summary R and S areas at the same points on the cartogram further improves the method's sensitivity.
