To examine gender differences in rate-corrected QT interval (QTc), an index of ventricular depolarization/repolarization, in young, trained men and women with lower ...

IN the atrial muscle of the heart the rate of depolarization (70–100 V./sec. at 30° C.) is so much more rapid than that of repolarization (less than 1.0 V./sec.) that the two events cannot be confused ...
