Abstract
Methods and systems for monitoring and modifying pulsed field ablation (PFA) energy delivery to prevent patient safety risks and/or delivery device failure. In particular, some embodiments provide methods and systems for detecting and preventing arcs and arc-induced plasma, and their causal events, during delivery of pulsed field ablation energy, as well as methods and systems for identifying conditions leading to potential delivery device failure and correcting charge imbalance or asymmetry.
