Quantitative spatial vector ECG in healthy humans of 20-44 yr of age indicated a more distinct decrease in the ventricular depolarization vector than in the repolarization vector with increasing age. This led to a decrease in vector correlation (MQRS/MT). The changes depended on a decrease in the mass of electrically active heart tissue due to coronary atherosclerosis and age-related myocardial degeneration and atrophy.
