Effect 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...
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 کاملImpact of Catheter Contact Force on Human Left Atrial Electrogram Characteristics in Sinus Rhythm and Atrial Fibrillation.
BACKGROUND During left atrial mapping, optimal contact parameters minimizing variation secondary to catheter contact are not established. METHODS AND RESULTS Across 30 patients undergoing first-time atrial fibrillation ablation, 1965 stable mapping points (1409 atrial fibrillation, 556 sinus rhythm), comprising 8-s contact force (CF) and bipolar electrogram data were analyzed. Points were tak...
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 کاملAutonomic innervation, atrial electrogram morphology, and atrial fibrillation.
everal lines of evidence suggest that autonomic innervation lays a role in the generation of atrial fibrillation (AF). anglionated plexi (GPs) that modulate autonomic inneration have been identified over both atria, particularly the ulmonary vein (PV) antral regions. Stimulation of GPs esults in the local release of parasympathetic and sympahetic neurotransmitters, which may lead to increased a...
