CORRELATION BETWEEN BLOOD VOLUME AND AMPLITUDE OF QRS COMPLEX IN YOUNG HEALTHY INDIVIDUALS
Journal Title: IJAR-Indian Journal of Applied Research - Year 2018, Vol 8, Issue 4
Abstract
Back ground Hemodynamic instability following trauma is perhaps the commonest cause of loss of life. The standard vital signs used to determine hemodynamic status are static measurements rather than dynamic, and may not truly reflect early volume loss. The Brody effect proposes a direct relationship between the QRS complex voltage and ventricular blood volume, a theory which has been supported by both human and animal studies. Aim To correlate blood volume and amplitude of QRS complex. Material and Methods Lead II ECG was recorded for 1 min in 56 healthy adult male volunteers (20-40 years) using the student Physiograph(Bio Devices). The amplitude of the largest QRS complex was measured in μV. Blood volume (in litres) was calculated by Nadler's method using height and weight. RESULTS: Blood volume showed positive correlation with QRS amplitude.
