Volume overload
![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.](/Images/godic/202502/07/Response_of_cardiac_stroke_volume_to_ventricular_filling_under_normal_conditions4025.jpg")
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.
