Figure 5.

The proportion of ECGs for which the participants gave a correct or incorrect initial diagnosis and subsequently changed to a correct or incorrect final diagnosis, or not. The ECGs are categorized as to whether the participants had no mobile device, could search the Internet, or access the ECG app. Whilst junior (A) and senior medical students (B) were influenced by searching the Internet or accessing the ECG app when changing an incorrect initial diagnosis to a correct final diagnosis, this was not true for medical residents (C). Overall (D), the greatest gains were present with ECGs for which participants had access to the ECG reference app.
