Â§ events just before and during diastole: Â§ during systole â A-V valves are closed Ã  atria filled with blood Â§ beginning of diastole â ventricular pressure decreases below that of the atria Ã  A-V valves open Â§ higher pressure in the atria pushes blood into the ventricles during diastole Â§ period of rapid filling of the ventricles occurs during the ...
