Sistema de tele-monitoreo inalámbrico de eventos cardiacos para seguimiento de arritmias

Abstract

Telemedicine schemes that allow the monitoring of patients with cardiovascular pathologies are an increasing necessity, especially for arrhythmia detection and monitoring. This paper describes the development of a telemonitoring scheme based on GSM/GPRS data transmission technology that emphasizes in the record and transmission of cardiac events. In this scheme the patient wear a small monitoring device which acquire the electrocardiogram (ECG), processes the signal using algorithms for heart rate calculation and serious arrhythmias detection by means of phase space reconstruction; stores the events in a removable memory card; and transmits the signals if an signal abnormality detection occur. The information is send to a specialized center of cardiovascular monitoring, where it can be evaluated by a physician, who can make a diagnosis without requiring patient displacement. The different components of the system have been validated through different tests confirming their functionality. © Springer-Verlag Berlin Heidelberg 2007.
