Overview

Cardiac changes such as LVH and heart block secondary to stenosis of bicuspid aortic valves may be observed on electrocardiography.

Electrocardiogram

Example of extreme left ventricular hypertrophy in a patient with severe aortic valve stenosis

Electrocardiogram among patients with bicuspid aortic stenosis may demonstrate features of left ventricular hypertrophy which may occur as a result of the stenosis having placed a chronically high pressure load on the left ventricle. As the left ventricular wall becomes thicker, the QRS complexes become larger. This is especially true for leads V1-V6.

The calcification process which occurs in aortic stenosis can progress to extend beyond the aortic valve and into the electrical conduction system of the heart. Evidence of this phenomenon may include heart block that is apparent on the ECG but otherwise undetectable.
