Fixed Perfusion Defects
Transmural Inferior Wall MI
Case history/ Imaging data
SPECT myocardial perfusion studies were performed using Tc-99m-Sestamibi. Images representing myocardial perfusion were obtained at rest and peak stress.

Stress protocol
  • Treadmill / Bruce
    • Duration of stress
  • 12 min 51 sec
    • Peak heart rate (85%)
  • 60 --> 154 (85%=143)
    		•
    Systolic BP (basal --> peak)
  • 124 --> 190
    		•
    Double product (peak rate x BP)
  • 29,300
    		•
    Reason for termination
  • Fatigue. Atypical mild chest discomfort
    • ECG findings
  • >2 mm horizontal ST depression
    		•
