Women And Cardiac Arrhythmia
Numerous prominent electrophysiological variations have been noted between the sexes. By 5 years of age, girls have a higher heart rate than do boys, which might be explained by a shorter sinus node refractory time. The shorter QT interval in men is cited for the duration of puberty, as intercourse hormone degrees upward push. The length of the QT interval in men increases linearly through adulthood until the age of 50, when it becomes similar to that of women, which correlates with the decrease in androgen levels. Furthermore, QRS amplitude and duration are greater in men, consequent to a higher cardiac mass and thicker left ventricular walls Effects of Sex Hormones
