PurposeThe purpose of this study was to evaluate the effect of aortic valve replacement on electrocardiogram (ECG) in patients with aortic valve stenosis.MethodsSerial 12-lead ECGs were obtained in 15 patients with aortic valve stenosis who underwent aortic valve replacement. Three ECG indexes for left ventricular hypertrophy were manually measured in each ECG: Sokolow-Lyon index (sum of S wave in V1 and R wave in V5), Cornell voltage index (sum of R wave in aVL and S wave in V3), and Gubner index (sum of R wave in I and S wave in III).ResultsAfter aortic valve replacement, Sokolow-Lyon index gradually decreased during 2 years (51.1 ± 17.9 to 34.8 ± 12.5 mm, P < .01). Cornell voltage index (25.6 ± 7.0 to 15.0 ± 4.8 mm, P < .01) and Gubner index (15.8 ± 7.6 to 10.3 ± 5.5 mm, P < .01) also gradually decreased during 2 years. ST depression in V6 was found in 14 patients (93%) before aortic valve replacement. It resolved in 9 of 14 patients during 2 years.ConclusionsElectrocardiographic evidence of left ventricular hypertrophy gradually resolved after aortic valve replacement in patients with aortic valve stenosis.
