The book highlights the growing importance of mobile telemedicine systems, particularly for patients far from healthcare facilities. It describes a project focused on the development of an ECG signal acquisition board, with chapters covering various technical and practical aspects, such as cardiology fundamentals, Java technologies and the implementation of specific components. The project provided expertise in programming and understanding cardiac activities, despite the practical challenges encountered. Future prospects include detecting arrhythmias and improving alerts for cardiac anomalies, as well as exploring GPRS transmission for data processing.
