Background & objectives: Hypertension, heart failure, ischemic heart diseases and valvular heart diseases are among the prevalent cardiovascular diseases in India as well as foreign countries. Impedance Cardiography (ICG) is very easy and effective non-invasive method to measure cardiac parameters like stroke volume, cardiac output, systemic vascular resistance, left ventricular ejection time and few others. Aim of this study is to check the utility of ICG in outpatient department for progression or improvement of heart diseases, change or modification of treatment and to check overall hemodynamic status of patients. Objectives are to measure all cardiac parameters in normal healthy persons as well as heart disease patients and to see the effect of disease on these cardiac parameters. Methods: This study was carried out in 80 normal healthy adult volunteers and 80 adult patients of various heart diseases like HT, IHD, CCF or Valvular heart diseases. Recording of cardiac parameters was done in Nivomon computerised automatic machine at Government Medical College & Sir T. Hospital, Bhavnagar. Results: All cardiac parameters' values were consistent with normal standard values in healthy volunteers. There was no significant difference between 2 groups for SV & SI. Both CO & CI were significantly lower in disease patients. Further, both SVR & SVRI were significantly higher in patients. So CO values were low because heart has to work against higher after load (SVR). Interpretation & conclusion: There was significant correlation between different parameters & different factors affecting those parameters. All cardiac parameters were measured effectively in normal healthy volunteers as well as in patients according to their hemodynamic status. ICG is very easy and accurate non-invasive technique and so it should be promoted more in country like India with less man power and more patients load

Abstracts: Background: The menstrual cycle is characterized by fluctuations in several hormones, most notably the gonadal steroids, estrogen and progesterone.¹ Sympathetic function tests are the one of the autonomic function tests and it is easy, non invasive test to be carried out. They give us idea about role of gonadal hormone in sympathetic control of cardiovascular system during different phases of menstrual cycle. Aim: Aim of this study is to determine whether fluctuation of reproductive hormone during premenstrual and post menstrual phases affecting sympathetic function tests or not. Objectives: To do and compare sympathetic function tests in pre and post menstrual phase. Methods: Study was carried out in 50 adult healthy female having age group of 26-40 years. Sympathetic function tests were carried out by instrument Cardiac Autonomic Nervous System Analyzer (CANS) 504 in Department of Physiology, Government Medical Collage, Bhavnagar. Sympathetic function tests were done using standard protocol and statically analyzed. Results: Statically significant difference was seen between premenstrual phase and postmenstrual phase in all sympathetic function test parameters which includes supine systolic and diastolic blood pressure, blood pressure response to standing and systolic blood pressure response after sustained hand grip test. Interpretation & conclusion: According to this study sympathetic dominance is seen in premenstrual phase of menstrual cycle that may be due to increased level of progesterone and oestrogen in premenstrual phase.
