absence of repolarization abnormalities in the presence of changes in QRS complex.3-9 The I-map has also been demonstrated to be useful in detecting disparity of repolarization that is closely related to susceptibility to malignant arrhythmias.10-16 It has been reported that the T wave change associated with left ventricular hypertrophy (LVH) is mainly secondary to QRS changes such as increases in ventricular activation time and R wave amplitude.'7 Analyses of QRST time integral values are
