Depolarizes

The process by which the electrical charge of a cell's membrane is reduced, leading to the possibility of generating an action potential.

Left Atrial Pressure

The pressure within the left atrium of the heart, important in evaluating heart function, particularly in conditions affecting left ventricular filling.
