Electrophysiological Evaluation of the Continuity and Transmurality of Surgical Ablation Lesions in Ex Vivo Perfused Porcine Hearts by Unipolar High-Resolution Mapping

Introduction: Currently, there is no method available for intra-operative evaluation of the completeness (transmurality and continuity) of surgical ablation lesions. This study aimed to investigate the changes in electrogram characteristics and activation patterns caused by different (non)transmural and (dis)continuous ablation lesions in ex...

Evaluating morphological patterns in atrial epicardial potentials: Clustering of time series potentials during atrial fibrillation

Introduction: Potentials measured at the epicardial surface contain information regarding the conductive properties of the atrial tissue. The current lack of morphological categorization during atrial fibrillation (AF) provokes the usage of unsupervised learning methods to evaluate time series electrograms across the atrial surface. Analysis of...
