Vectorcardiograms in 163 clinical subjects of normal and various abnormal conditions obtained by Frank lead system and in 17 dogs of experimental myocardial injury or intra-ventricular conduction disturbances by McFee-Parungao method were transformed by exchange of axes of co-ordinates by the method of McFee et al. The non-planarity index, from the axes of the transformed frontal plane, was significantly higher during myocardial injury and bundle branch blocks as well as from diffuse intra-myocardial conduction disturbances than during normal clinical cases and the control records in animal experiments. The non-planarity index was not increased in localized block of the conduction system in dogs. Therefore, results suggest that this index might be a useful parameter to assess these conditions.
