Because of spatial variations in the precise timing of depolarization and repolarization in different parts of the heart, current flows between cardiac regions during the overall depolarization ...

The QT interval is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization. The normal QT ...

This is referred to as “LVH with QRS widening.” Also, repolarization may be affected via similar mechanisms that can result in abnormal ST segments or T waves. This is referred to as “LVH ...
