Detection of QT interval in ECG using first and second derivative
Rybár, Andrej ; Smital, Lukáš (referee) ; Chrobák, Martin (advisor)
This bachelor´s thesis deals with QT interval measurement and detection. The thesis starts with problematic of ECG signal delineation and its methods of detection of QT interval using first and second derivate. Next part of the work describes QRS complex detector. For this detection it is suitable to use detector based on the Pan-Tompkins algorithm. Next in practical part of the work is described algorithm of the detection of QT interval using first and second derivate. Selected algotithm was evaluated on the standard CSE database. Detected positions were compared with reference values. Result of this work is evaluation of results.
