Validation of the V-index as a metric of ventricular repolarization dispersion using intracardiac recordings
2015 Computing in Cardiology Conference (CinC)
The spatial heterogeneity of ventricular repoalarization (SHVR) is an important factor in arrhythmogenesis and it is related to increased vulnerability to fatal arrhythmia. The V-index is a non-invasive estimator of SHVR based on the analysis of the surface ECG. A significant correlation between the V-index and SHVR has been previously demonstrated theoretically and by means of numerical simulations. Also, the V-index has been shown to track expected changes in SHVR after infusion of drugs thatdoi:10.1109/cic.2015.7411000 dblp:conf/cinc/OriniBFHLSM15 fatcat:ps6zzaw6n5c3lfw72pob5uulwy
