Overview
In aortic regurgitation, the electrocardiography findings are nonspecific. Electrocardiographic abnormalities in the patient with aortic regurgitation include left axis deviation and signs of left ventricular hypertrophy.[1]
Electrocardiogram
Electrocardiographic abnormalities in the patient with aortic regurgitation include:[1][2][3]
- Nonspecific changes of ST and T wave (due to left ventricular enlargement)
- Right coronary artery ischemic changes (suggestive of aortic dissection)
- ST elevation in II, III, aVF (inferior MI)
- ST elevation in V3R and V4R (right ventricle MI)
- ST depression in V1-V3 (posterior MI)
- 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)
- Re-polarization abnormalities
- ST-segment depression in precordial leads
