As the observed reduced septal uptake of both 201Tl and 99mTc-sestamibi/tetrofosmin in LBBB reflects coronary autoregulation in response to lower oxygen demands, not surprisingly, dipyridamole which uniformly exploits flow reserve, has proven more accurate for the diagnosis of coronary artery disease (CAD) in patients suffering from LBBB. In addition, a small-sized, moderate perfusion defect is noted in the left circumflex artery territory that is completely Stress-induced perfusion abnormalities in regions that exhibit normal perfusion at rest are termed reversible perfusion defects, and such regions represent viable, ischemic tissue with blunted coronary blood flow reserve. tid Furthermore, the frequency of abnormalities found on MPI increases over time with right ventricular outflow tract pacing.
