Review of Dominant Frequency Analysis in Atrial Fibrillation.
Significant advancements have been made in the technology and approach to catheter ablation of atrial fibrillation (AF). Pulmonary vein isolation has emerged as the dominant strategy in this procedure and has fueled innovations in catheter design as well as various mapping and navigation systems. Mapping and targeting of complex fractionated atrial electrograms has also emerged as an additional...
متن کاملComplex fractionated atrial electrograms, high dominant frequency regions, and left atrial voltages during sinus rhythm and atrial fibrillation
BACKGROUND Ablation targeting complex fractionated atrial electrograms (CFAEs) or high dominant frequency (DF) sites is generally effective for persistent atrial fibrillation (AF). CFAEs and/or high DF sites may exist in low-voltage regions, which theoretically represent abnormal substrates. However, whether CFAEs or high DF sites reflect low voltage substrates during sinus rhythm (SR) is unkno...
متن کاملEvaluation of the characteristics of rotational activation at high-dominant frequency and complex fractionated atrial electrogram sites during atrial fibrillation
BACKGROUND High-dominant frequency (DF) and continuous complex fractionated atrial electrogram (CFAE) sites as surrogates for localized sources maintaining atrial fibrillation (AF) are potential AF ablation targets. This study aimed to evaluate the characteristics of a rotational activation at high-DF and continuous CFAE sites in AF patients. METHODS Thirty-two consecutive AF patients (5 paro...
متن کاملEfficacy of atrial substrate modification based on dominant frequency of paroxysmal atrial fibrillation
BACKGROUND The endpoint of ablation procedures is suggested to be non-inducibility of paroxysmal atrial fibrillation (PAF). However, the prognosis of induced AF/atrial tachycardia (AT) after pulmonary vein isolation (PVI) in PAF patients remains unclear. METHODS A total of 122 PAF patients were divided into the following 3 groups: Group 1, 79 without AF/AT induced after PVI; Group 2, 21 with ...
متن کاملEffect of adenosine triphosphate on left atrial electrogram interval and dominant frequency in human atrial fibrillation.
BACKGROUND Complex fractionated atrial electrograms (CFAEs) and high dominant frequency (DF) are targets for atrial fibrillation (AF) ablation. Although adenosine triphosphate (ATP) is known to promote AF by shortening the atrial refractory period, its role in the pathogenesis of CFAEs and DF during AF is not fully understood. METHODS We recorded electrical activity from a 64-electrode basket...
