Definitions:

Intraventricular Pressure

The pressure within the ventricles of the heart, which varies during different stages of the cardiac cycle.

Incompetent Mitral Valve

A condition where the mitral valve in the heart does not close properly, leading to backward flow of blood from the left ventricle into the left atrium, affecting heart efficiency.

Left Atrium

The heart chamber that receives oxygenated blood from the lungs and pumps it to the left ventricle.

Mean Arterial Pressure

The average blood pressure in an individual's arteries during one cardiac cycle, essential for ensuring effective tissue perfusion.
