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.
Objective: To investigate any change in heart rate, PR interval and duration of ST segment in ECG during different phases of menstrual cycle.
30 apparently healthy female aged between 18-25 years were selected for the study and ECG was recorded using Electrocardiograph during the different phase of menstrual cycle:- a): Menstrual phase(MP) (2nd day), b): Proliferative phase(PP) (11th day) c): Secretory phase(SP) (22nd day).
Results: Statistical analysis paired t-test was done by using online statistical calculator. There was statistical significant change in Heart rate, PR interval and ST segment duration. HR is increased more as compared to menstrual phase, it showing p-value of 0.000133 in paired t-test between Menstrual phase with secretory phase. There was no statistical significant change in PR interval during proliferative change on comparison with menstrual Phase.
Conclusion: Cyclical fluctuation of hormones during menstrual cycle changes electrophysiological parameters, affecting cardiovascular system.
