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.
Low-limb lead voltage, a pseudoinfarction pattern (Q waves) in leads III and AVF, and ST-segment elevation or depression in leads V4 to V6, elevation of troponin were the ECG findings for poor prognosis.
