Explain what happens en un digram con ECG, ventricular volume, and ventricular/aortic/atrial pressure

(Applies for left and right side, bueno mas right side si se habla del aortic pressure) First P wave is due to atrial systole, there's an increase in atrial pressure as it pushes blood into the ventricles. there is isovolumetric contraction as av valves are closed which explains the straight line in ventricular volume after it increases. ventricular pressure also increases slightly here because blood is rushing inside them. then the SL valves open and blood is pushed out the ventricles. this increases aortic and ventricular pressure, as ventricular volume decreases. This ventricular systole also explains the QRS wave in the ecg. Next, cualquier cosa to explain the aortic pressure, el dicrotic notch causes a decrease in aortic pressure as the blood tries to go back into the ventricles REAL QUICK, causing the SL valve to close and blood going back up the aorta, which again causes an increase in aortic pressure. When the SL valve closes, ventricular volume increases again as the av valve opens instead; with blood passively filling the ventricles again.
