The 12-lead Electrocardiogram (ECG) is the most widely used tool for non-invasive assessment of the heart. It is recorded using nine electrodes, which must be placed at specific locations on the body. However, 12 million ECGs are recorded incorrectly every year due to electrode misplacement. This can result in misdiagnosing patients, which means that certain patients will not receive adequate treatment and other patients will receive unnecessary treatment. Regardless, teaching methods such as textbooks and mannequins do not provide students with sufficient training on the effects of electrode misplacement. As a result, we developed a multimedia tool called the Electrode Misplacement Simulator (EMS). The EMS was given to a group of Clinical Physiology students to use in their own time whilst another group of students used traditional learning methods. Both groups were then given a class test and the EMS was shown to facilitate better understanding of the effects of electrode misplacement (t-test, p-value = 0.0012).
