We evaluated the electrocardiograms of 208 postmenopausal women (ages 40 to ≥70 years) without heart disease, medications that could alter the QT interval, use of vaginal estrogens, unknown hormone replacement therapy, or electrocardiographic abnormalities both with (n = 76) and without (n = 132) hormone replacement therapy, and found no significant effects of hormone replacement therapy status on heart rate, QT interval, or the corrected QT interval. Thus, estrogen and/or progesterone effect does not explain the gender differences in myocardial repolarization.
