Sistema de adquisición, transmisión y análisis de señales de ECG

Abstract

Present job describes a development for an ECG acquisition, transmission and ECG analysis system. The acquisition equipment has several functions as digitalize the signal, save the signal on a Compact Flash card, or send them to PC or other USB connection. This equipment is based on PIC 16F873 microcontroller and performs all the functions helped by periferical devices as amplifiers, isolated amplifiers, isolated power switch, active filters, etc. Transmission is performed by a G20 Motorola chip that works on GSM network. The signal is sent by that network to a precise Internet IP node, in order to see on this PC the signal in real time. ECG analysis is based on Wavelet transform algorithms. Complementing that equipment it was developed an Internet page http://www.frsn.utn.edu.ar/holter/ where the equipment can load the signal with another data of the patient in order to see by the doctor anywhere. © Springer-Verlag Berlin Heidelberg 2007.
