Realization and development of a tool Hard/soft for detection of cardiac abnormalities

In this article we are interested in the cardiac signal processing. Then, a system for collecting and digitizing the cardiac signal has been implemented and processing algorithms were developed. The cardiac signal from an electrodes network attack an amplification card based on an AD620 instrumentation amplifier. The analog to digital conversion is assured by the DaqBoard 1000 acquisition card. The signal so digitized will undergo a series of treatment to be able to detect the place of peaks R and calculate the width of the segment QS. As analysis we chose the detection of the rhythmic irregularities. To confirm our results, we applied our algorithms to a some signals from the MIT database.
