    A 56-year-old male patient was admitted with an evolved inferior wall myocardial infarction (IWMI). Electrocardiogram (ECG) showed presence of ST elevation and T wave inversion in the inferior leads. ECG taken on the next day surprisingly showed features suggestive of acute high lateral wall myocardial infarction (LWMI), without features suggestive of re-infarction which was finally diagnosed to be an artefact due to lead reversal. Lead reversal between left arm and left leg can mimic as high LWMI in a case with IWMI and we should aware of this situation before misdiagnosing it as re-infarction.

    Key words: Lead reversal, Inferior wall MI, Lateral wall MI, Re-infarction.
