WebCoronary arteries and coronary sinus. What are the pressure changes in the atria and ventricles during a cardiac cycle? When the atria are relaxed, the pressure begins to rise as they fill with blood. As the atria contract, the pressure rises suddenly, forcing the remaining blood into the ventricles.
