Ventricular pressure follows the events in the cardiac cycle. The atrioventricular valves (mitral and tricuspid valves) close before ventricular systole which allows pressure to build rapidly in the left and right ventricles. At the end of the systole, the valves open and the pressure falls rapidly. This then leads to the period of rapid filling of the ventricles. The values for ventricular pressure becomes inversely proportional to that of ventricular volume during the events in the cardiac cycle.
