We evaluated the accuracy of low dose dobutamine radionuclide ventriculography (Dob RNV) for detecting myocardial viability. Dob RNV was performed and compared with reinjection of 201 Tl imaging in 20 patients with old myocardial infarction.

• 采用小剂量多巴酚丁胺（Dob）负荷试验与核素心室造影（RNV）相结合的方法（DobRNV）对20例陈旧性心肌梗塞（OMI）患者进行存活心肌的评估并与201铊（Tl）再注射心肌断层显像（SPECT）相比较。
