  3. 3. Ventricular ECGfilling Phonogram 120 Atrial pressure > Ventricular pressure(mid to late diastole) Pressure (mmHg) AV valves open Atrium contract 80 Blood flow from atrium to ventricle 40 Atrial pressure < Ventricle pressure AV valves close RA 0 LA LV Ventricular filling RV Atrial Contraction
  4. 4. Ventricular ECGsystole Phonogram 120 AV valves closed(atria in diastole) Ventricles contract Pressure (mmHg) 80 Ventricular Pressure > Ao/Pa Pressure 40 Ao/Pa valves open LV/RV eject blood into 0 Ao/Pa Isovolumic contraction phase Ventricular ejection phase
