• Anterior wall myocardial infarction
• Anteroseptal myocardial infarction

Background: In traditional literature, it appears that "anteroseptal" Mls with Q waves in V1-V3 involve basal anteroseptal segments although studies have questioned this belief
Methods: We studied patients with first acute anterior Q-wave (>30 ms) MI. All underwent late gadolinium enhancement (LGE) cardiac magnetic resonance imaging (MRI).
Results: Those with Q waves in VI-V2 (n = 7) evidenced LGE > 50% in 0%, 43%, 43%, 57%, and 29% of the basal anteroseptal, mid anteroseptal, apical anterior, apical septal segments, and apex, respectively. Patients with Q waves in VI-V3 (n = 14), evidenced involvement was 14%, 43%, 43%, 50%, and 7% of the same respective segments. In those with extensive anterior Q waves (n = 7), involvement was 0%, 71%, 57%, 86%, and 86%.
Conclusions: Q-wave MI in VI-V2N3 primarily involves mid- and apical anterior and anteroseptal segments rather than basal segments. Data do not support existence of isolated basal anteroseptal or septa] infarction. "Anteroapical infarction" is a more appropriate term than "anteroseptal infarction.
