Technical errors in electrocardiography acquisition can deviate from the correct diagnosis, ensuing in unnecessary workups and hospital billings. A keen understanding of lead placement concepts and the Einthoven triangle helps avoid these unwanted paths. Here, we presented the case of a 57-year-old woman with a history of hypertension and chronic kidney disease who came to the hospital due to chest pain. Initially, ischemic changes in her electrocardiogram (ECG) were noted. However, the correct placement of ECG leads confirmed the "counterclockwise lead placement" of this patient. This case report highlighted the underrecognized types of ECG lead reversals.
