Summary

Although pulmonary vein arrhythmogenicity plays a critical role in initiation and perpetuation of atrial fibrillation (AF) particularly in patients with paroxysmal AF, mechanisms beyond the pulmonary and other thoracic veins appear to be critical in perpetuation of AF. Among these mechanisms are the multiple wavelet hypothesis, autonomic modulation, and high frequency sources (rotors). In this chapter the role of frequency of mapping to eliminate high frequency sources is discussed in detail based on experimental data and clinical studies.
