In aortic insufficiency, the electrocardiographic findings are nonspecific. However, the following may be noted:
- Left ventricular hypertrophy
- Left axis deviation
- Left atrial enlargement
- Left ventricular volume overload pattern (prominent Q waves in leads I, aVL, and V3 to V6 and relatively small r waves in V1)
- Left ventricular conduction defects (typically late in the disease process)
- Repolarization abnormalities
- ST-segment depression in precordial leads
