Left ventricular diastolic filling response to stationary bicycle exercise during pregnancy and the postpartum period
Article Abstract:
Exercise during pregnancy appears to cause the heart muscle to become stiffer and also changes the rate at which the heart fills with blood after contraction. However, pregnancy alone does not cause these changes.

Effects of pregnancy on the electrocardiogram in healthy subjects during strenuous exercise
Article Abstract:
Pregnancy may normally be associated with electrocardiographic changes during exercise. Researchers obtained electrocardiograms from 39 pregnant women in early and late pregnancy and from eight nonpregnant women during bicycle exercise tests. Pregnant women exhibited more T-wave inversions in V2 than nonpregnant women. In late pregnancy, women had much fewer small Q waves. Pregnant women achieved maximum ST depression much sooner than nonpregnant women during exercise. Pregnant women did not experience any adverse cardiac effects from exercise.

Ventricular filling patterns of the right and left ventricles in normally grown fetuses: a longitudinal follow-up study from early intrauterine life to age 1 year
Article Abstract:
Researchers report the first known study that analyzed how the fetal heart fills after each contraction beginning at the 16th week of pregnancy and continuing to the age of 12 months after birth. Doppler ultrasound was used to determine filling patterns at 16 weeks, every 4-6 weeks thereafter until birth, and at the ages of 1 and 2 days, 6 weeks, 6 months and one year. Results show that the fetal heart has filling properties similar to adults with heart disease. The heart was stiffer and the right side of the heart was dominant rather than the left.
