Real time mapping QRS duration based on wavelets

The pacing for permanent pacing in bradyarrhytmias can influence ventricular activation and can contribute to marked asynchrony in extremity. In this work, we search the optimal position for right ventricular pacing according the QRS duration. We evaluate the system for detection of QRS boundaries based on wavelet transform and adaptive threshold. The system is used during pacemaker implantations in Department of Cardiology, Heart Center, Hospital Podlesi Třinec. Streszczenie. W artykule zaprezentowano system do detekcji QRS bazujący na transformacie falkowej. System sprawdzono w Klinice serca w Tryncu podczas implantacji rozrusznika serca. (Analiza w czasie rzeczywistym QRS bazująca na transformacie falkowej).
