Definitions:

Dicrotic Notch

A slight dip observed on the descending limb of the arterial pulse waveform, representing a brief increase in aortic pressure following closure of the aortic valve.

Semilunar Valves

Heart valves located between the ventricles and the major arteries, preventing backflow of blood into the heart chambers.

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.
