Key result
Counterclockwise ECG lead misplacement can mimic diffuse ischemia, highlighting the importance of recognizing abnormal P-wave configurations with unchanged precordial morphology to avoid unnecessary workups.
Why the study?
Technical errors in electrocardiography acquisition can lead to incorrect diagnoses, unnecessary workups, and extra hospital costs, making recognition of lead placement concepts critical.

ECG lead errors may mimic ischemia; case reports leave open prevalence and verification protocols.
Prasitlumkum et al. (2022) conducted a case report in ECG lead misplacement (n=1). Counterclockwise ECG lead misplacement vs. Normal ECG lead placement was evaluated. Counterclockwise ECG lead misplacement can mimic diffuse ischemia, highlighting the importance of recognizing abnormal P-wave configurations with unchanged precordial morphology to avoid unnecessary workups.
