Viability...: Depending on the institution, usually rest delayed thallium or FDG pet is performed to evaluate for myocardial viability.
Alternatively Dobutamine may be used. Low-dose Dobutamine infusion may result in potentiation of regional lv function in areas of hibernating myocardium. High-dose Dobutamine infusion will result in worsening regional abnormalities secondary to ischemia.
