Caption: Electrocardiogram (ECG) indicating aortic stenosis, left ventricular hypertrophy and atrial fibrillation. An ECG records electrical activity in the heart; certain patterns are characteristic of disease conditions. The ink pattern is recorded on a strip of moving paper from electrodes placed on skin of all four limbs & the chest wall; a total of 12 electrodes are typically used. Aortic stenosis is the narrowing & incapacity of the aortic valve, the valve between left ventricle (heart's largest chamber) & aorta, the body's major blood vessel. Ventricular hypertrophy describes an abnormally enlarged ventricle caused by the defective valve. Atrial fibrillation describes the rapid & chaotic.
