Cyclical alteration in heart rate variability among young eumenorrheic women
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2018, Vol 5, Issue 3
Abstract
Introduction The female sex hormones are known to have a cardioprotective role in premenopausal women compared to postmenopausal women125 The key hormone estrogen and progesterone shows a cyclical variation along the different phases of menstrual cycle Parasympathetic activity via vagus is known to improve the cardiac function compared to sympathetic activity3 Heart rate variability HRV is one of the sensitive and noninvasive method to record the cardiac autonomic activity4 Thus we chose this study to assess how the female sex hormones affect autonomic activity on the heart during the phases of menstrual cycleAim To assess the effect of cyclical alteration in female sex hormones on cardiac autonomic activity by HRVMaterials and Methods After getting institutional ethics committee clearance short term HRV 5 minutes was recorded in fifty young female volunteers aged between 2030 years within normal range of BMI and regular menstrual cycle in supine posture after 10 minutes rest using PHYSIO PAC PP4 Medicaid system Chandigarh in the autonomic function lab Department of Physiology Sri Venkateshwaraa Medical College Hospital and Research Center Ariyur Pondicherry Statistical analysis was done using SPSS 17 versionResults The sympathetic parameters like low frequency domain LF nu LFHF ratio was significantly increased in the premenstrual phase The parasympathetic parameters like high frequency domain HF nu TP total power were significantly increased in the proliferative phase of the menstrual cycleConclusion Thus the cardioprotective role of female sex hormones in premenopausal women was more pronounced in the proliferative phase of menstrual cycleKeywords Heart rate variability Cardioprotective Premenstrual phase Proliferative phase
