Do different phases of menstrual cycle affect the HR, PR interval and duration of ST segment?: A study

Abstract

Introduction: Alteration in the release of female steroid hormones like progesterone and estrogen in a systematic manner is due to periodic ovarian variation. The alteration in female steroid hormones causes physiological alteration of cardiovascular activities and ultimately affects Electrocardiogram (ECG) parameters.
Aim: To analyze the heart rate and the changes in PR interval and duration of ST segment in ECG during menstrual phases.
