Electrocardiographic findings are nonspecific but may include evidence of the following:

  • LV hypertrophy

  • Left axis deviation

  • Left atrial enlargement

  • LV volume overload pattern - Prominent Q waves in leads I, aVL, and V3 to V6 and relatively small r waves in V1

  • LV conduction defects - Typically late in the disease process
