Pressure Volume Loop of Left Ventricle
Pressure-Volume Loop of Left Ventricle:
Pressure-Volume Loop of Left Ventricle:
• Pressure range:• 120 to 80 mmHg
• Volume range:• 120 to 50 ml
d to a
• During Diastole ventricle fills pressure increases from d to a.
a to b
• During Iso-volumetric contraction sharp rise in pressure from a to b.
b to c
• During ventricular ejection sharp rise in pressure.
Point c
• Aortic valve closes at point c.
c to d
• During Iso-volumetric Relaxation pressure falls from c to d.
