Q wave abnormality

WebAug 6, 2024 · A Q wave is a negative deflection before the R wave. The Q wave indicates the interventricular septum's usual left-to-right depolarization. Small 'septal' Q waves are often seen in the left-sided leads (I, aVL, V5 and V6) In most leads, little Q waves are typical. As a typical variation, deeper Q waves (>2 mm) may be found in leads III and aVR. WebConclusion: Abnormal Q waves on the admission electrocardiogram (ECG) are associated with higher peak creatine kinase, higher prevalence of heart failure, and increased …
