(A) Chest CT on admission. (B) Echocardiography showing ventricle size within normal range, increased atrium size and markedly decrease cardiac ejection fraction on admission. (C) Electrocardiogram showing sinus tachycardia, low voltage of limb leads, T wave inversion in anterior waves and V1-V3 QS type on admission.

Chest computed tomography (CT) examination indicated right bronchial obstruction, obstructive pneumonia and right pleural effusion (Figure 1A). Echocardiography revealed ventricle size within normal range (left ventricle end diastolic dimension 46 mm), increased atrium size (left atrium dimension LA 36 mm) and markedly decrease cardiac ejection fraction (left ventricular ejection fraction 41%), tracing 2 mm pericardial effusion (Figure 1B). The electrocardiogram showed sinus tachycardia, low voltage of limb leads, T wave inversion in anterior waves and V1-V3 QS type (Figure 1C). The electrocardiogram showed normal sinus rate and V2-V5 T wave inversion (Figure 1C). Echocardiography revealed ventricle size within normal range (left ventricle end diastolic dimension 48 mm), increased atrium size (left atrium dimension LA 30 mm) and markedly recovered cardiac ejection fraction (left ventricular ejection fraction 66%). The patient was discharged with prescription of continuing oral methylprednisolone (20 mg, once per day, po) and anti-bacterial therapy of faroenem to control infection (150 mg, q8h, po).
