Sistema de detección, registro y telemonitoreo de arritmias cardiacas

Abstract

The development of ambulatory electrocardiography systems in a telemedicine scheme is 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 wears a small monitoring device which acquires the electrocardiographic signal (ECG), processes the signal using algorithms for the calculation of heart rate and detection of serious arrhythmias by means of phase space reconstruction; stores the events in a removable flash memory; and transmit the signals if a signal abnormality detection occur. The information is sent 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.
