Dynamics of T-peak-to-T-end Morphology Changes in an Open-chest Porcine Model, and its Relation to Arrhythmic Events
In this work, we use a time-warping-based morphology variation index, dwPCATpe, computed between the peak and the end of the T-wave, and assess its association with the occurrence of ventricular fibrillation (VF) episodes (VF group) in ECG recordings from 20 pigs undergoing a 40-minute coronary occlusion. The dwPCATpe series was obtained by quantifying the morphological differences between the fin
