Echocardiography, focusing on cardiac function and dimensions, is needed to evaluate left ventricular (LV) function, septal thickness, and wall motion abnormalities and to help rule out cardiomyopathy and an associated congenital heart defect (CHD), such as hypertrophic cardiomyopathy [HOCM], Ebstein anomaly, or L-transposition of the great vessels. Significantly depressed function may be observed in the setting of an acute dysrhythmia but should typically normalize in the absence of an incessant tachycardia.
