ECG and XML: An instance of a possible XML schema for the ECG telemonitoring

Abstract

Management of many types of chronic diseases relies heavily on patients' self-monitoring of their disease conditions. In recent years, Internet-based home telemonitoring systems allowing transmission of patient data to a central database and offering immediate access to the data by the care providers have become available. The adoption of Extensible Mark-up Language (XML) as a W3C standard has generated considerable interest in the potential value of this language in health informatics. However, the telemonitoring systems often work with only one or a few types of medical devices. This is because different medical devices produce different types of data, and the existing telemonitoring systems are generally built around a proprietary data schema. In this paper, we describe a generic data schema for a telemonitoring system that is applicable to different types of medical devices and different diseases, and then we present an architecture for the exchange of clinical information as data, signals of telemonitoring and clinical reports in the XML standard, up-to-date information in each electronic patient record and integration in real time with the information collected during the telemonitoring activities in the XML schema, between all the structures involved in the healthcare process of the patient.
