Exercises for Heart Mechanics

II D  -  Varying the contractility of the ventricle.

The slider marked "Contractility" controls strength of the ventricular contraction during systole..
You will be asked to vary the contractility and notice what happens to the P-V loop.

The upper guideline represents the end systolic pressure-volume relation (ESPVR).
Clicking on "Reset" redraws ESPVR using the current Contractility setting.
Try changing the graph first without using Reset, then use it as needed.

Follow the instructions and click on the appropriate changes as in the previous exercise.
