Sistema de monitoreo de cardiaco para pilotos de combate en pleno vuelo

Abstract

This work presents the design of a cardiac monitoring system for pilots of the Colombian Air Force. The main goal is to continue using the voice channel of the aircrafts for sending both the voice signal and the ECG signal, without interfering one in another. The system is composed by two subsystems: the transmitter and the receiver. The transmitter one consist of the ECG acquisition circuit, the voltage controlled oscillator, a low pass filter and a signal adder. The receiver one consist of a low pass filter (in order to obtain the original voice signal) and the link to a personal computer through the sound card, which, by means of a mathematical software, the ECG signal is demodulated, filtered and visualized on screen. © Springer-Verlag Berlin Heidelberg 2007.
