title: [Deviation of the electrical cardiac axis to the left between -30 degrees and -90 degrees as an index of left ventricular hypertrophy].
abstract: The index of left ventricular hypertrophy A between --30 degrees and --90 degrees was established to be with low sensitivity (23 per cent) and high false positiveness (13 per cent) with the analysis of 448 electrocardiograms of 269 deceased, to 60 of them being applied the pathologoanatomical separating-gravimetric method of Fulton and to the rest--the classical methods. The disturbances of the intraventricular conductivity and especially the left anterior hemiblock contribute considerably. The left axial deviation in left ventricular hypertrophy was established not to be due mainly to the increased muscular mass but also to the accompanying or conditioned by it processes (coronary insufficeincy, sclerosis) leading to disturbances of the left ventricular conductivity.
