Early detection of ventricular fibrillation (VF) and fast ventricular tachycardia (VT) is crucial for the success of the defibrillation therapy. A wide variety of detection algorithms have been proposed based on temporal, spectral, or complexity parameters extracted from the ECG. However, these algorithms are constructed by considering each parameter individually. This study aimed to analyze the performance...
It has been previously documented that the main features and sensing performance of electrograms (EGMs) recorded in implantable cardioverter defibrillators (ICDs) depend on lead configuration. Although this dependence has been ascribed to differences in lead sensitivity and spatial resolution, the quantification of these two properties on ICD has not yet been attempted. In this paper, an operative...
Lead design is a critical factor for detecting and redetecting lethal arrhythmias in electrograms (EGM) from Implantable Cardioverter Defibrillators (ICD). The estimation of the scope of a lead can help to elucidate the anatomical origin of recorded EGM and explain signal features. In this paper, we compare quantitatively the scope of true and integrated bipolar sensing leads by combining bioelectric...
