Web-based and mobile system for training and improving in the field of electrocardiogram (ECG)

The aim of this work is to promote the application of computer science and skills in projecting web-based and mobile systems for training and improving in the field of biomedical engineering. The main role of such project system is reflected in unification and publishing educational contents in the fields of ECG signals, assigned for students and teachers of medicine and biomedical engineering. The system may also feature realistic ECG signals and support both learning and examination. The proper interpretation and detecting of different waves and intervals of electric heart activities are of primary interest for the application of computer systems in processing of the ECG signals. The presentation of this signal has been performed in several different ways, where each of them helps better understanding of certain anomaly that occurs in it. Several algorithms for the detection of QRS complex have been analyzed and compared, and the algorithm showing best results by several criteria, has been implemented. The additional possibility is the signal analysis in the form of heart rate variability. In order to be widely used, the application has been realized in the form of content management system (CMS). In this structure, the implemented system is a typical example of three-layer software architecture.
