Key result
Left arm to right arm ECG lead reversal falsely simulates postero-lateral MI.
Why the study?
Misplacement of electrocardiogram leads is not rare and can mimic myocardial infarction, leading to emotional distress, unnecessary testing, potential harm, and increased healthcare costs.
Case Report (n=1)
Clinicians must consider improper ECG lead placement (MISFIT) when an electrocardiogram diagnosis of myocardial infarction does not fit the clinical scenario to avoid unnecessary and potentially harmful interventions.

Consider lead reversal in mismatched ECG-MI diagnoses; case reports leave open incidence and verification protocols.
Cohen et al. (2024) conducted a case report in Myocardial infarction simulated from improper telemetry (MISFIT) (n=1). Improper telemetry (ECG lead misplacement) vs. Correct ECG lead placement was evaluated. Improper placement of electrocardiogram leads, specifically a left arm to right arm reversal, falsely simulated a postero-lateral myocardial infarction in a 58-year-old man.
