The ECG Mobile Application is a learning application resulting from a collaboration between the Department of Cardiology and Vascular Medicine and the UGM Faculty of Engineering. Mobile ECG adapts the concept of the Massive Open Online Course (MOOC) to improve the EKG competence of students and health workers through online course materials. With the existing features, it is hoped that users can learn and understand material according to the competency standards of Indonesian general practitioners in an attractive, comprehensive and structured manner.
