To the Editor: In their study of patients with electrocardiographic left ventricular hypertrophy (LVH), Dr Okin and colleagues1 identify an association between LVH regression as measured by the Cornell product and decreased risk of atrial fibrillation. They cite a prior study2 of this simple and low-cost electrocardiographic measure that shows a correlation with LVH.
