Isovolumetric relaxation occurs during the cardiac cycle when the ventricles are relaxing but all valves are closed, preventing any change in volume. This phase is represented by the segment from point E to point A in a pressure-volume (PV) loop, as it shows a decrease in pressure without a change in volume.
