The electrocardiograms (ECGs) in this Atlas supplement those illustrated in Chap. 11. The interpretations emphasize findings of specific teaching value.

All of the figures are from ECG Wave-Maven, Copyright 2003, Beth Israel Deaconess Medical Center,

The abbreviations used in this chapter are as follows:

  • AF—atrial fibrillation

  • HCM—hypertrophic cardiomyopathy

  • LVH—left ventricular hypertrophy

  • MI—myocardial infarction

  • NSR—normal sinus rhythm

  • RBBB—right bundle branch block

  • RV—right ventricular

  • RVH—right ventricular hypertrophy


Figure 41-1

Anterior wall ischemia (deep T-wave inversions and ST-segment depressions in I, aVL, V3−V6) in a patient with LVH (increased voltage in V2−V5).

Figure 41-2

Acute anterolateral wall ischemia with ST elevations in V4−V6. Probable prior inferior MI with Q waves in leads II, III, and aVF.

Figure 41-3

Acute lateral ischemia with ST elevations in I and aVL with probable reciprocal ST depressions inferiorly (II, III, and aVF). Ischemic ST depressions also in V3 and V4. Left atrial abnormality.

Figure 41-4

Sinus tachycardia. Marked ischemic ST-segment elevations in inferior limb leads (II, III, aVF) and laterally (V6) suggestive of acute inferolateral MI, and prominent ST-segment depressions with upright T waves in V1−V4 are consistent with associated acute posterior MI.

Figure 41-5

Acute, extensive anterior MI with marked ST elevations in I, aVL, V1−V6 and small pathologic Q waves in V3−V6. Marked reciprocal ST-segment depressions in III and aVF.

Figure 41-6

Acute anterior wall MI with ST elevations and Q waves in V1−V4 and aVL and reciprocal inferior ST depressions.

Figure 41-7

NSR with premature atrial complexes. RBBB; pathologic Q waves and ST elevation due to acute anterior/septal MI in V1−V3.

Figure 41-8

Acute anteroseptal MI (Q waves and ST elevations in V1−V4) with RBBB (note terminal R waves in V1).

Figure 41-9

Extensive prior MI involving inferior-posterior-lateral wall (Q waves in leads II, III, aVF, tall R waves in V1, V2, and Q waves in V5...
