From: Evaluation of a web-based ECG-interpretation programme for undergraduate medical students
The learning object presents one of the ECG cases in the interactive ECG interpretation module. The cases are based on a clinical history. The student is asked to interpret the ECG. One of the tools they can use for this purpose is the special moveable ruler. The ECG can be magnified together with the ruler for measuring the components of the ECG-complex. The student's interpretation can be compared with the interpretation of an expert.
