Abstract
BACKGROUND AND OBJECTIVES: Inaccurate electrocardiography (ECG) lead placement may lead to erroneous diagnoses, such as poor R wave progression. We sought to assess the accuracy of precordial ECG lead placement amongst hospital staff members, and to re-evaluate performance after an educational intervention. METHODS AND RESULTS: 100 randomly selected eligible staff members placed sticker dots on a mannequin, their positions were recorded on a radar plot and compared to the correct precordial lead positions. The commonest errors were placing V1 and V2 leads too superiorly, and V5 and V6 leads too medially.Following an educational intervention with the aid of moderated poster presentations and volunteer patients, the study was repeated six months later. 60 subjects correctly placed all leads, compared to 10 in the pre-intervention cohort (P<0.0001) with the proportion achieving correct placement of any lead rising from 0.34 to 0.83, (p<0.0001 for all leads). CONCLUSION: Incorrect ECG lead placement is common. This may be addressed through regular training incorporated into annual induction processes for relevant health care professionals.
