WebA 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. This can indicate a blockage. WebDefect-related trapping levels are ascribed to the intrinsic defects, and the defects generated as a consequence of doping. Doping-related defects include strain and …
