Left ventricular pressure-volume loop



  • a: Closure of mitral valve (S1)
  • b: Opening of aortic valve
  • c: Closure of aortic valve (S2)
  • d: Opening of mitral valve.

Events taking place:

  • During diastole, the ventricle fills and pressure increases from d to a
  • Pressure then rises sharply from a to b during isovolumetric contraction
  • Pressure falls slightly during ventricular ejection from b to c
  • At c, the aortic valves close and pressure falls during isovolumetric relaxation from c to d.
