A resting ECG trace may show evidence of an enlarge left atrium (wide P wave), an enlarged left ventricle (tall R wave, wide QRS complex, shift of mean electrical axis to the left) and rhythm disturbances such as sinus tachycardia, [[Atrial Fibrillation|atrial fibrillation]], [[Supraventricular Premature Complexes|atrial premature complexes]] and atrial tachycardia.

Electrocardiography is primarily used to diagnose arrhythmias, but can provide evidence of chamber enlargement. Most arrhythmias in DMVD are supraventricular in origin and occur secondary to left atrial stretch. Ventricular arrhythmias may develop in association with left ventricular dilation and fibrosis.
