Abstract
Background
Hemodynamic instability following trauma is perhaps the commonest cause of loss of life. The standard vital signsused 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.
