Briefly what are the stages of the cardiac cycle

First there is atrial systole which leads to the the closure of the AV valve so there is isovolumetric contraction until there is opening of the outflow valves where there is then rapid ejection phase where blood enters the arteries Then there is isovolumetric relaxation and the outflow valves close which then leads to ventricular systole and diastasis which then leads to atrial systole and the cycle repeats
