We herein report a case of a false positive vasodilatory pharmacologic SPECT stress test in the setting of a left bundle branch block (LBBB). While this is more commonly seen with exercise stress testing, it can also occur with pharmacologic stress testing. In our SPECT exam, we illustrate the commonly mistaken septal/anteroseptal perfusion defects in those patients with a LBBB. PET stress testing may be more reliable for patients with LBBB.
我们在此报告一例左束支传导阻滞（LBBB）患者行血管扩张药物负荷 SPECT 心肌灌注显像出现假阳性的病例。虽然这种情况在运动负荷试验中更为常见，但也可发生于药物负荷试验。在我们的 SPECT 检查中，我们展示了那些 LBBB 患者中常见的被误认为是间隔/前间隔灌注缺损的图像。对于 LBBB 患者，PET 负荷试验可能更为可靠。
