Training example with a "normal subject" data set. Clicking on the "view graphics" button opens the graph results sheet. For each calculated variable rest-peak changes are graphically displayed with heart rate values on the x-axis and variable value on the y-axis. LV elastance index at peak stress is nearly twice as large as arterial elastance index, with ventricular-arterial coupling normally set toward higher left ventricular work efficiency. Stroke volume increases through the use of the Frank-Starling mechanism and heart rate. Systemic vascular resistances drop markedly at peak exercise.
