Software for Access to Publicly Available ECG Signal Databases

U ovom radu bavimo se ispisom EKG signala, detekcijom QRS-a i grafičkim sučeljem (GUI). U radu koristimo tri standardne MIT-BIH baze. Svaka baza sadrži određen broj signala, a svaki signal prikazujemo pomoću tri datoteke: zaglavne (.hea), podatkovne (.dat) i anotacijske (.atr). Za ispis signala koristimo Exporter koji iz danih datoteka ispisuje EKG signal zajedno s anotacijama. GUI korisniku daje mogućnost odabira EKG baze i signala, odabir broja kanala koji se ispisuju te vrijeme početka i završetka ispisa signala. Korisnik ima i mogućnost odabira algoritma za detekciju R-vrhova te prikaz ocjene algoritma. Sve funkcije pokreću se pomoću grafičkog sučelja, pritiskom na tipku.This paper deals with the ploting of ECG signal, QRS detection and graphical interface (GUI). Three standard MIT-BIH bases are used in the paper. Each base contains certain signals and each signal is represented by three files: header (.hea), data (.dat) and anotation (.atr). ECG signal is ploted by Exporter who prints it from start time to end time along with annotations. The GUI allowa the user to select the ECG base and signal, to select the number of channels, the start time and the end time of the printing signal. The user has the option of selection the algorithm to detect R-peaks and display the algorithm rating. All functions are triggered by a graphical interface by pressing the key
