Abstract
The 3 leads of the cube lead system and the conventional 12 lead ecg were recorded with a scalar electrocardiograph in 119 normal subjects and 42 subjects with arterial hypertension or aortic regurgitation. The vertical lead QRS was mainly negative, transverse lead QRS mainly positive and sagittal lead QRS symmetrical diphasic in the majority of normal subjects and in some with LVH. The vertical lead QRS was mainly positive in 7 of 119 normals and in 16 of 42 subjects with LVH.Keywords
