Electrogram-Gated Delivery of Duty Cycle Radiofrequency Energy During Simulated Lateral Sliding Catheter Movements in a Thermochromic Myocardial Phantom The electrogram sense switch circuit was gated ...

Abstract: Epicardial wavefront conduction patterns during atrial fibrillation (AF) can be recorded using high-density contact mapping. Quantification of electrogram morphology similarity at adjacent ...

Electrogram morphology is used to identify the atrio-ventricular annuli during catheter ablation procedures with a "balanced" signal considered to represent the annuli. However, anatomical studies ...

Multiple analysis techniques evaluate electrograms during atrial fibrillation (AF), but none have been established to guide catheter ablation. This study compares electrogram properties recorded from ...

Fractionated electrograms are used by some as targets for ablation in atrial and ventricular arrhythmias. Fractionation has been demonstrated to result when there is repetitive or asynchronous ...

Abstract: During radiofrequency ablation procedures for atrial fibrillation patients, physicians can assist in locating ablation targets by analyzing the conduction pathways and low-voltage areas of ...
