Volume overload

Not to be confused with Hypervolemia.
Representation of the cardiac response in stroke volume to left ventricular filling under normal conditions. There is an optimum end-diastolic volume at which maximum stroke volume and cardiac output is achieved. Beyond this, there is volume overload, and stroke volume is diminished.

Volume overload refers to the state of one of the chambers of the heart in which too large a volume of blood exists within it for it to function efficiently. Ventricular volume overload is approximately equivalent to an excessively high preload. It is a cause of cardiac failure.[1]
