Left Ventricular Pump Function
The heart is a cleverly designed organ that propells blood around the body. Satisfactory performance depends on competent cardiac valves and powerful contraction of cardiac muscle. The heart’s performance is often compared to that of a hydraulic pump where efficiency is computed as the ratio of work performed to oxygen consumed. Any understanding of the factors governing left ventricular performance must begin with the events of the cardiac cycle.
