Stroke volume is the amount of blood ejected by the ventricle in one beat and is determined by ventricular preload, afterload, and contractility. How can stroke volume be decreased?
a) Increase heart rate
b) Increase ventricular contraction
c) Decrease aortic pressure
d) Decrease total peripheral resistance
Guess I'm having a hard time visualizing why A is correct, and why the other options are incorrect.
I know cardiac flow = heart rate x stroke volume.
a) so, (cardiac flow/heart rate)...
