QT Dispersion (QTd) refers to the difference in QT interval between leads of 12-lead body surface electrocardiogram and reflects the inconsistency of ventricular repolarization and ECG instability [1]. Our department from June 2000 to February 2012 admitted in January of 80 cases of essential hypertension (EH) and left ventricular hypertrophy (LVH) in 80 patients, compared with no LVH (control group) compared QTd The changes of QTd in EHLVH patients were investigated
