Treadmill ECG
Treadmill-ECG performed: Exercise capacity 9.7 METS, 88% age-predicted max HR, with normal ECG but atypical chest pain: Stress echo is requested
Stress Echocardiogram
In this case, stress echo itself was key to the diagnosis (and possibly life-saving) which was missed by treadmill-ECG, while perfusion imaging, as often in cases of very severe / subocclusive proximal stenosis, did not add to wall motion information
