A fixed defect is a perfusion defect present at stress and rest. It came down after medicine and an over night stay. Perfusion is the volume of blood flowing through certain mass (or volume) of tissue per unit time. While there are multiple etiologies of ventilation-perfusion mismatch, the most common causes include acute and chronic pulmonary embolism, a tumor obstructing an artery, and radiation therapy.

Ejection Fraction refers to the percentage of the blood in your heart that is pumped out with each beat. ant/apical ischemia. Conclusions: Perfusion defects are associated with an increase in pulmonary artery pressure (PAP) and functional limitation. It is critical to determine whether it is a predominantly reversible defect or only a minimally reversible abnormality. A perfusion defect is an SMALL area of the heart with diminished blood flow under stress. Reversible means that it was not see at rest so it can be reversed as it is not always there which could indicate dead heart muscle from a previous MI, but only under stress.
