SYSTEM AND METHOD FOR DISCRIMINATING PREMATURE VENTRICULAR CONTRACTION AND A RECORDING MEDIUM WITH A PROGRAM PERFORMING THE SAME

摘要

PURPOSE: A system and method for discriminating premature ventricular contraction and a recording medium with a program performing the same are provided to warn patients by detecting the variation of an ECG(electrocardiogram) in an early stage.;CONSTITUTION: A signal preprocessing unit(110) forms a sum signal by converting an ECG signal into wavelet and adding up the converted signals. An algorithm processing unit(130) sets an R wave threshold value and a window distance for detecting an accurate R wave. An R wave detector(120) detects the R wave by comparing an amplitude value of the sum signal and the R wave threshold value within the window distance. A variable calculating unit(140) calculates an RR distance and an QRS width using the detected R wave. A PVC discriminating unit(150) discriminates the kind of ventricular contraction using the RR distance and the QRS width.;COPYRIGHT KIPO 2013;[Reference numerals] (112) Wavelet converter; (114) Signal filter; (116) Signal adding up unit; (120) R-wave detector; (132) Threshold setting unit; (134) Window setting unit; (142) RR interval calculation unit; (144) QRS width calculation unit; (150) PVC determining unit; (AA) ECG signal
