Slurred q wave
WebbDepolarization continues (slowly) towards the left ventricular free wall, and the vector is continuosly directed leftward. This causes a wide S-wave in V1–V2 (it is referred to as QS complex if the r-wave is absent) and broad … Webb14 apr. 2024 · Q wave localized only to lead aVL can be due to the electrical position of the heart and does not necessarily suggest myocardial infarction. QS configuration in leads V1 and V2 is part of electrocardiographic findings of LBBB and does not suggest myocardial infarction. Abnormal Q waves in leads V 3, V 4 suggest infarction (Figs. 25.13 and 25.14).

Well if you notice, V 2 to V 6 are almost identical; this makes us think that the technician who performed the test had some serious lead placement problems. Remember, leads I and V 6 should be identical. The qR' complex develops in patients who have an RBBB and an old anteroseptal MI; hence, the Q wave.
