What is stroke volume?

The stroke volume (SV) is the amount of blood (mL) ejected per heartbeat by the LV into the aorta (or from the RV into the pulmonary artery) assuming that all the blood leaving the ventricle is ejected into the outflow…

Cardiac function

CO = SV × HR Where:Cardiac output = CO (mL/minute or liters/minute)Stroke volume = SV (mL/beat)Heart rate = HR (beat/minute) resting cardiac output differs among individuals of different size cardiac output is often expressed as a flow (L/min) per body…
