What is Ventricular Preload? The degree of myocardial stretch and is DIRECTLY related to VENOUS RETURN.
With Preload: Increase VR equals what? Increase Stroke Volume
With Preload: Decrease VR equals what? Decrease Stroke Volume
What is Ventricular Afterload? The resistance of force against which the ventricle must work to pump blood.
With Afterload: Increase SVR/PVR equals what? Decrease Stroke Volume
