Procesamiento digital sobre monitor cardíaco

Abstract

In this work we considered to take the obtained data from basic a cardiac monitor and by means of the use from digital signal processing (DSP) to come to improve the characteristics and benefits of the same one. This monitor was developed as didactic-experimental equipment in the Laboratory of Bioelectrónica of the Department of Electronic Engineering of the Technological University National Regional Faculty Cordoba is a device of under cost able to acquire the twelve derivations with three simultaneously. Its structure consists of a block analogical, that the function fulfills to acquire and to prepare the signal of the ECG, and a digital stage, that turns the analogical values to words digital which are processed with DSP techniques. In this work they evaluated the use of diverse digital filters, in aspects such as, run time, conditions for its implementation, amount and type of variables. On the other hand it was come to compare the result of the implementation of these techniques with the data obtained without her. The final equipment is a monitor, portable electrocardiograph and of low cost, able to be implemented with different configurations from digital filters or without them, all it with the purpose of allowing to its application in the degree education, postdegree and applied investigation. © Springer-Verlag Berlin Heidelberg 2007.
