Abstract

Background: Isolated septal myocardial infarction (MI) is traditionally characterized by the presence of pathological Q waves in leads V₁ and V₂ on the surface electrocardiogram (ECG). The purpose of this study was to determine the relation between this ECG pattern and septal scar on cardiac magnetic resonance (CMR) imaging. Methods: We retrospectively reviewed the medical records of 996 consecutive patients who received both ECG and CMR. Results: Nineteen patients had a Q wave in leads V₁ and V₂. Septal scar was present in all 19 patients. Based on CMR imaging criteria, septal scars were ischemic in 8 patients (42%) and non-ischemic in 11 patients (58%). Conclusion: The results suggest that the presence of a QS pattern in leads V₁ and V₂ on the surface ECG is highly predictive of the presence of a septal myocardial scar, but is not diagnostic for septal MI, even after excluding comorbidities known to produce a pseudo-septal MI pattern.
