Preprost prenosni elektrokardiograf (EKG)

Elektrokardiografija je proces spremljanja električne dejavnosti srca. Najpogosteje se uporablja za diagnosticiranje morebitnih obolenj srčne mišice, nudi pa tudi druge možnosti uporabe. Cilj diplomske naloge je prikaz elektrokardiograma in frekvence srčnega utripa na zaslonu. V ta namen smo za spremljanje električne aktivnosti srca uporabili modul EKG, ki s pomočjo treh elektrod pridobi elektrokardiogram srca. Znotraj operacijskega sistema FreeRTOS tečeta dve opravili. Prvo opravilo izvaja preprost algoritem za zaznavo srčnega utripa, ki hkrati meri čase med posameznimi utripi in iz njih izračuna frekvenco srčnega utripa, drugo opravilo pa skrbi za posodabljanje elektrokardiograma in izpis frekvence srčnega utripa na zaslon.

Abstract

Electrocardiography is the process of recording the electrical activity of the heart. It is mostly used for diagnosing a wide variety of possible heart diseases, although there are other possible uses. The aim of this dissertation is to display the electrocardiogram and the heart rate on a screen. For this purpose we utilized an ECG board which uses three electrodes to acquire the electrocardiogram of the heart. There are two tasks running inside the operating system FreeRTOS. The first task contains an algorithm used for detecting the heart beat and measuring the time between the two heart beats. The second task is used to update the data displayed on the screen.
