Key result
Pregnancy was associated with an increase in heart rate and QTc interval and a decrease in PR interval compared to non-pregnant controls, peaking during the 3rd trimester.
Why the study?
Does pregnancy alter ECG intervals (heart rate, PR, QT, QTc) compared to non-pregnant women?
Cross-Sectional (n=223)
Does pregnancy alter ECG intervals (heart rate, PR, QT, QTc) compared to non-pregnant women?
Pregnancy is associated with significant changes in cardiac electrical activity, including increased heart rate and QTc interval and decreased PR interval, particularly in the 2nd and 3rd trimesters.

May inform ECG interpretation in pregnancy; leaves open arrhythmia risk validation in prospective studies.
Kole et al. (2014) conducted a cross-sectional in Pregnancy (n=223). Pregnancy vs. Non-pregnant females was evaluated on Heart rate, PR, QT interval and QTc. Pregnancy was associated with an increase in heart rate and QTc interval and a decrease in PR interval compared to non-pregnant controls, peaking during the 3rd trimester.
