Abstract
The shortcomings of electrocardiographic time measurements from single leads have been noted before. With the use of simultaneously recorded corrected, orthogonal leads it is possible to evaluate better the time phase relationships of the electrocardiogram. The present study involves a statistical analysis of measurements of the P-wave duration, P-R interval, P-R segment, Q-T duration, and Q-T ratio of a group of 133 normal subjects.
