Phase 0 Results N/A

Summary of Purpose

Hypothesis: A validated technique to measure cardiac output (CO) using echocardiography is to calculate stroke volume from the product of LVOT area and LVOT VTI and multiplying the product with heart rate ( CO = SV x H/R; SV = LVOT area x LVOT VTI ). The LVOT diameter for an individual is more or less a constant measurement. Therefore using the formula mentioned above (SV = LVOT area x LVOT VTI), if the LVOT...
