Data from: “Automatic Supporting System for Regionalization of Ventricular Tachycardia Exit Site in Implantable Defibrillators” Sanromán-Junquera, Margarita; Mora-Jiménez, Inmaculada; Almendral, Jesús; García-Alberola, Arcadio; Rojo-Álvarez, José Luis. IDPatient: patient identifier NumberOfPacingSite: pacing site number Half-1: apical vs basal half Half-2: septal vs lateral half Half-3: superior vs inferior half TypeOfTissue: scar or normal tissue: 2 ( > 1.5 mV), 1 (1.5 - 0.5 mV), 0 (< 0.5 mV). X: X coordinate of the pacing site Y: Y coordinate of the pacing site Z: X coordinate of the pacing site Vp: voltage of peak deflection Vi: voltage of initial deflection Vf: voltage of final deflection tob: time interval between the onset of far-field electrogram and the bipolar intrinsic deflection tp: time instant of Vp ti: time instant of Vi tf: time instant of Vf Far-fieldEGMWaveformWithStim: averaged beat waveform far-field electrogram BipolarEGMWaveform: averaged beat waveform bipolar electrogram.
