Some individuals will receive an electrocardiogram when their doctor suspects that they have a heart problem. Of course, this includes possible aortic stenosis. Patients will have electrodes and wires attached to their skin during this test. The wires will connect to a device to measure the electrical activity of the patient’s heart. Elements that electrocardiograms can detect include enlarged heart chambers as well as abnormal heart rhythms. The abnormal heart rhythm is a particularly important part of detecting aortic stenosis with an electrocardiogram. However, patients often need more than this test to diagnose aortic stenosis.
