1,2) By the same token ST-segment depression in lead III, the reciprocal lead to I and aVL, (3) may be more impressive than the ST elevation in those leads in high lateral ischemic injury (Figure).
S waves in lead I and Q waves in lead III with T-wave inversion in III); 5) shift in the transition zone (R5S) to V5 or further leftward; 6) complete or incomplete RBBB; 7) peripheral low voltage (in the limb leads); 8) pseudoinfarction pattern (prominent Q waves) in leads III and aVF; 9) ST segment elevation 0.
Amplitudes were highest in lead III and were so low as to be virtually immeasurable in lead I.
