An electrocardiogram (ECG) showed sinus tachycardia, low voltage, poor progression of R-wave in precordial leads, incomplete LBBB, extreme right axis deviation with RV strain, S1 Q3 inverse T3 pattern, Q-wave in 2-3 AVF suggestive of old MI (Figure 1).

Transthoracic echocardiography (TTE) revealed severe left ventricular (LV) and left atrial (LA) dilatation, extremely impaired systolic function with left ventricular ejection fraction (LVEF) below 15% (actual was 8%), full size RV, normal mitral and aortic valve, normal aortic root size (Figure 2).
