Abstract

In 424 men and 142 women, clinically "healthy," ages 40 through 59 years, significant sex differences in electrocardiographic characteristics were found. The differences were minor in the limb-lead amplitudes (P, Q, R, S, T), but QRS and P-R duration was significantly shorter in women. Precordiallead amplitudes (R, S, T) were significantly smaller in women. Present normal standards derived from groups of men are not valid for women.
