Myocardial infarction or technical artifact?
Misplacement of recording electrodes can generate misleading patterns on the standard 12-lead electrocardiogram (ECG). Some lead placement errors are easily recognizable, others are more difficult to detect and can be quite important in risk selection because the resulting changes in ECG morphology can mimic other conditions such as myocardial infarction. Therefore, identification of incorrectly performed ECGs is an important task for the medical director.
