There may also be tall R waves in the right precordial leads, suggestive of a posterior wall acute MI; T-wave inversions are sometimes seen in these leads with prominent R waves (Figure 2F). Normal variant (or benign) causes
WebWe concluded that in anterior wall STEMI, the prominent Q wave in lead -aVR is associated with severe regional wall motion abnormality in the apical and inferior regions, with the long LAD. Further studies are needed to clarify the clinical and prognostic significance of the prominent Q wave in lead -aVR in anterior wall MI and non-anterior ... WebSep 22, 2024 · They are characterized by inverted P-waves in the inferior leads and an upright P-wave in lead aVR, reflecting retrograde atrial depolarization (toward aVR and away from lead II). The inverted P-waves in the inferior leads may appear before or after the QRS complex; or, commonly, if atrial and ventricular depolarization occur concurrently, the …
