Electrocardiography (ECG) provides critical information regarding a patient's cardiovascular health; however, research has shown that errors in the use of ECG by healthcare providers are common. Improper application of patches and leads and incorrect interpretation of readings can result in unnecessary and costly intervention, or worse still, a failure to provide life‑saving treatment when actually needed. Currently available training tools can address these potential issues, but they can be prohibitively expensive. There exists a need for an affordable and portable training system for healthcare providers to ensure proper use of an ECG and accurate interpretation of readings.


A clinical nursing instructor and a biomedical engineer at Montana State University are collaborating on an inexpensive system to train healthcare workers in the appropriate use of an ECG device and the correct interpretation of results. The system combines a simple anatomical diagram, patches, leads and wires, with a digital training app which can be downloaded onto a mobile device. The system guides users through the correct placement of leads and further presents a series of readings requiring the user to assess a patient's condition. Perhaps most important, the system presents users with readings that result from common errors in lead placement, requiring a user to troubleshoot and identify and correct the errors. The associated app is being designed for both the system user and instructors who need to evaluate system users' progress in mastering ECG administration. A prototype is currently being tested and refined.
