It´s all about mesure readings within the ventricles.
It´s a rapid fall in pressure within the ventricles after systole, then the ventricles start filling again during dyastole increasing pressure just to stop suddenly (creating a plateou when pressure is mesuraed) I guess no more blood enters the ventricles and stays in both atrial chambers contribuiting to make equal pressure mesures because of the restrective cardiac walls due to chronic constrictive pericarditis (cardiac walls can not expand because of the harden pericardum). (Sorry for my English).
You will see on the pressure reading paper a drawing like a square root sign /°°°°°
