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.

This nearly magical quality ascribed to the ECG should not be ignored, as it may create disease where none is present, reassure falsely, or even be a healing force. It has been demonstr

Limits and Continuity of Functions,was set correctly, since recording the electrocardiogram (ECG) at a 50 mm/sec paper speed instead of the usual 25 mm/sec will cause apparent lengthening of the intervals. Abnormalities of conduction manifesting as alterations in the cardiac rhythm were discussed in Chapter 5. Alterations in the axis

Single Women in Popular Culturesually refers to the QRS axis. As previously noted, the axis can be measured by determining the lead in which the sum of the areas over and under the baseline is zero. 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

Description of Visual Field Defects,phic (ECG) findings to physiological and anatomical inferences. For example, to state on the basis of the ECG abnormality of tall, peaked P waves in limb lead II that there is “right atrial hypertrophy” is risky indeed. It is preferable to simply state what the abnormality is and let the patient’s p
