Key result
Arm-leg electrode transposition mimics simultaneous anterior and inferior STEMI from a wrap-around LAD occlusion.
Why the study?
Acute STEMI rarely affects two coronary artery territories simultaneously, and unusual ECG abnormalities may be due to incorrect lead placement rather than true dual territory infarction.
Case Report (n=2)
When confronted with unusual ECG abnormalities like simultaneous anterior and inferior STEMI, incorrect lead placement should be considered, though a wrap-around LAD is a genuine anatomical cause.

Millar et al. (2017) conducted a case report in Acute STEMI / ECG abnormalities (n=2). ECG interpretation was evaluated. Apparent simultaneous anterior and inferior STEMI on ECG can result from left arm and left leg electrode transposition, whereas genuine cases may occur due to a wrap-around LAD occlusion.
