Abstract

Transient or intermittent depression of the ST-segment may precede diagnostic ST-segment changes at peak exercise or during recovery. Such changes also suggest underlying myocardial ischemia especially if changes are seen in identical beats in more than one leads and are associated with elevation of the ST-segment in identical beats in lead aVR. Such changes may occur only in one beat and may be accompanied by rapidly down sloping Pq segment.
