Left-deviated AQRS

Figure 5.30 Typical example of inferior myocardial infarction (Qr in II, III and VF) with leftward AQRS. Nevertheless, the left-deviated AQRS (-35°) is not explained by an added superoanterior hemiblock (SAH), but simply by the inferior necrosis, because although the majority of the QRS loop in the frontal plane is above 0°, as it completely rotates in the clockwise sense, a small terminal r (Qr morphology) in II, III and VF is recorded. If an added SAH exists, the first part of the loop would be the same, but would later rotate in the counter-clockwise direction and would generate QS with notches but without the final r wave in inferior leads.

In spite of the left-deviated AQRS, Figure 5.30 shows that there is no SAH associated with the inferior infarction, since the QRS loop is always rotating in the clockwise direction. With the surface ECG we can suspect that there is no coexisting... [Pg.189]
