FIG1
A 12-lead electrocardiogram (EKG) (Figure 1) showed diffuse inferior and anterolateral ST-segment depression.
Echocardiogram with reduced ejection fraction concerning for stress cardiomyopathy.. Echocardiogram revealed severely depressed left ventricular systolic function, with a calculated ejection fraction of 28% with apical and mid-anterior akinesis (red arrow) and preserved basal wall motion, suspicious of stress cardiomyopathy.

FIG2
Follow-up echocardiogram with a significantly improved ejection fraction.. Three days later, echocardiogram showed a remarkable improvement in overall wall motion abnormalities and an LVEF of 50%. Focal areas of akinesis involving the mid-anterolateral and mid-anterior segments (red arrow).

FIG3
A repeat Echo on day four (Figure 3) showed an LVEF of 50%.
Day four electrocardiogram revealed an old anterolateral infarct.. Day four electrocardiogram showing sinus rhythm, first-degree arteriovenous block, borderline right axis deviation, old anterolateral infarct (Q wave in v4, v5, and v6 pointed by blue arrows), and borderline prolonged QT interval.
