The Significance of ST Depression in a Postmenopausal Woman on Estrogen Therapy during Regadenoson Myocardial SPECT Imaging

<div>Resting (a) and stress (b) EKG tracings on patient undergoing regadenoson SPECT exam while taking chronic conjugated estrogen therapy. With pharmacologic stress, the patient developed 1.5 mm ST depression in the inferolateral distribution at a heart rate change of 50 (resting heart rate 61, peak stress heart rate 116, ΔST/ΔHR = 2).</div>
