You are incorrect - the best interpretation of the electrocardiogram in our patient is left ventricular hypertrophy and left atrial enlargement.

Your choice: Increased left ventricular voltage
This electrocardiogram shows increased left ventricular voltage.

The characteristic features demonstrated here include the tall R waves in leads V4 through V6. No other abnormalities are seen. The electrocardiogram of young and/or thin chested individuals may demonstrate such increased voltage without left ventricular hypertrophy or any underlying cardiac disease.
