2. Figure 1
A, Isolated right ventricular AMI. Note the diagnostic ST-segment elevation in leads III and V1, nondiagnostic ST-segment in lead II, and ST depression with terminal upright T waves in leads I and aVL (ie, reciprocal changes from right lateral injury). Since lead V1 injury = V2R injury, and right lateral injury = V6R injury, theoretically this patient should have injury in leads V2R to V6R. B, Right ventricular leads in same patient confirming injury in leads V2R through V6R.

3. Figure 2
A, 12-lead ECG demonstrating an isolated acute posterior AMI. Note the prominent R wave, horizontal ST-segment depression, and upright T wave in leads V3 through V6. B, Upside down mirror image of Figure 2A representing classical ST-segment elevation in leads V3 through V6.

4. Figure 3
12-lead ECG demonstrating electrocardiographic AMI in the setting of LBBB. Note the concordant ST-segment elevation in leads I, aVL, V5 and V6. Also note the excessive discordant ST-segment elevation in leads V1 through V4.

5. Figure 4
AMI in the presence of RBBB. Note the pseudonormalization of ST segments in lead V1 with concordant ST segment elevation ≥1 mm in leads V2 through V4. Also note early Q wave formation in leads V1 through V5. Unlike LBBB, anterior Q waves are not obscured by the presence of RBBB.
