Reversible Perfusion Defects
Moderate Severe Ischemia
Case history/ Imaging data
SPECT myocardial perfusion studies were performed using Tc-99m-Sestamibi with Dobutamine and Atropine. Images representing myocardial perfusion were obtained at rest and peak stress.

Stress protocol
  • Dobutamine / Atropine
    • Duration of stress
  • 13 min 10 sec
    • Heart rate (basal --> peak)
  • 80 --> 160 (85%=151)
    		•
    Systolic BP (basal --> peak)
  • 106 --> 120
    		•
    Double product (peak rate x BP)
  • 19,200
    		•
    Reason for termination
  • Protocol achieved. Typical chest pain
    		•
    ECG findings
  • Upsloping ST changes
    		•
