Misplaced ECG electrodes and the need for continuing training
Abstract
More than 1 million ECGs are recorded every day. This literature review examined the accuracy of electrode placement (EP) when acquiring a standard 12-lead electrocardiograph recording (STLER), and the consequences of inaccuracy. The findings showed that EP accuracy varies from 16–90%, and standards and guidelines on EP are not being adhered to. Poor EP can mean under- or overdiagnosis, which can increase morbidity and mortality, or mean that patients receive unnecessary treatment or hospitalisation. Mandatory, appropriate training and assessment, including before an operator is allowed to acquire a STLER and refresher training for ECG operators, are recommended.
