DUGARTE J, Nelson; ALVAREZ, Antonio; DUGARTE, Edinson y ALVAREZ, Gabriel. Techniques HRECG signal processing applied at DIGICARDIAC prototype. INHRR [online]. 2015, vol.46, n.1-2, pp.84-106. ISSN 0798-0477.
This paper reports the development stage of the electrocardiographic signal processing implemented at the prototype DIGICARDIAC. The DIGICARDIAC prototype is a medical instrument that allows the simultaneous acquisition of the twelve-lead electrocardiogram (ECG) standard, which features high resolution (HRECG). The software developed, aims to bring together some of the criteria set up by the researchers and implement some new techniques, in heartbeat detection and measurement of QT and ST intervals in the HRECG signal acquired with the system. The algorithm efficient was proved through tests of perfomance. The errors obtained in QRS complex detection are lower than 0,1% and measuring QT interval averaging 1.89% error in the ECG signals of the control patients was obtained.
