Does incorrect 12-lead ECG electrode placement alter ECG patterns and diagnosis in patients with suspected heart disease?
Incorrect 12-lead ECG electrode placement, particularly of leads V1 and V2, can yield waveforms that mimic or conceal myocardial infarction, potentially leading to patient harm and wasted resources.
