Radiofrequency ablation (RFA) therapy is the gold standard in interventional treatment of many cardiac arrhythmias. A major obstacle is nontransmural lesions, leading to recurrence of arrhythmias. Recent clinical studies have suggested intracardiac electrogram (EGM) criteria as a promising marker to evaluate lesion development.

Article Synopsis
- Intracardiac electrograms are essential for diagnosing and treating cardiac arrhythmias, but their variability can complicate interpretation.
- Simulations of these electrograms help clarify how factors like catheter position and contact affect the signals.
- In this study, simulated electrograms were validated against real recordings, showing a strong correlation in timing and signal width across various catheter orientations.
