Abnormalities of the ST Segment, the ST segment, the shape (concave or convex upward) and the slope are sometimes as important as the absolute degree of ST-segment elevation or depression. Associated T wave changes are also important. The large number of factors affecting the ST segment often makes interpretation difficult. In add

The Electrocardiogram in Childhood,t rate, and conduction differences related to the physical size of the heart. In addition, high voltages may be seen because of the thin chest wall. Patterns of repolarization that would be abnormal in an adult are quite common in children and may persist into the teens and occasionally beyond.

The vector is thus perpendicular to this lead and must be in one of two directions. By examining the lead at right angles to this le
