NON-INVASIVE MEASUREMENT OF CARDIAC PARAMETERS IN OUTPATIENT DEPARTMENT
Journal Title: International Journal of Basic and Applied Physiology - Year 2017, Vol 6, Issue 1
Abstract
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.
