    Abstract

    Left ventricular hypertrophy is a powerful predictor of death. Hypertensive subjects with left ventricular hypertrophy can have increased QT (end) dispersion, which is associated with cardiac death. Despite its prognostic value, QT (end) dispersion is not widely used. QTp (i.e. start of QRS to peak of T wave) is easier to measure. Therefore, we tested the hypothesis that long QT peak was associated with left ventricular hypertrophy and assessed its cost-effectiveness at diagnosing left ventricular hypertrophy.
