case_images: Transthoracic echocardiogram findings at the emergency department visit. LVDd, left ventricular internal dimension in diastole; LVDs, left ventricular internal dimensions in systole; FS, fractional shortening; LAD, left atrial dimension; AoD, aortic root diameter; IVC, inferior vena cava; TR-PG, tricuspid regurgitation peak gradient; ECG, electrocardiogram; EF, ejection fraction; LV, left ventricle; E/A, early-to-late transmitral velocity; DcT, deceleration time; AR, aortic regurgitation; MR, mitral regurgitation; TR, tricuspid regurgitation; PR, pulmonary regurgitation; SH, severe hypokinesis.

case_images: An electrocardiogram (ECG) showed sinus tachycardia (Supplementary Figure S1). TTE showed a diffusely reduced LV wall motion and an LVEF of 21.6% (Figure 1).
