A Study on the Direction of Inscription of the Vectorcardiographic T-Loop in Left and Right Ventricular Hypertrophy

Abstract
The vectorcardiographic loop was classified into 8 types according to the direction of inscription in 3 planar projections. Types of the T-loop were examined with the spatial orientation of it and some characteristic types observed in left and right ventricular hypertrophy were described. The concept of the polar vector was used in expressing types of the loop and in studying geometrical properties of it.
