A study of vector electrocardiography.

The vector electrocardiographic method was applied on 126 healthy young Korean adults without any evidence of cardiac diseases. The range of the age of the subjects were between 19 and 34. The normal values of the magnitude and direction of the mean QRS, T, P vectors, ventricular gradient and QRS-T angle in frontal plane were presented and discussed in comparison with those previously reported in the literature. Considering the age of the subjects under study, our results were in general agreement with those previously reported by other authors.
