(1) Frank lead vectorcardiogram was recorded in 30 normal persons and in 323 cases with hypertension and acquired and congenital heart disease. The T-loop was classified into 8 types according to the directions of inscription in 3 planar projections. Frequently observed types were examined with the direction of the maximal T vector.(2) In majority of normal cases, the T-loop was inscribed counterclockwise in horizontal and clockwise in sagittal planes.(3) In left ventricular hypertrophy, abnormal inscription of the T-loop was observed with abnormal rightward and superior deviation of its maximal vector and the T-loop oriented more than 120° in horizontal plane was usually accompanied by abnormal inscription. Percentage of abnormal inscription was higher in cases with cardiac complaints.(4) In right ventricular hypertrophy, directional change of the T-loop was relatively small but changes in inscription of it were common. The T-loop was always inscribed abnormally in cases with abnormal inscription of the QRS-loop.(5) The concept of the polar vector was found to be valuable in studying the inscription and the direction of the T-loop. Significance of changes in inscription of the T-loop was discussed.
