Targeting Atrial Fibrillation Rotors
T he hypothesis that rotors or areas of rapid reentry are critical to maintenance of atrial fibrillation (AF) has gained considerable currency with clinical data supporting enhanced efficacy when targeting these sites in AF ablation (1–3). Regions bordering AF rotors have been shown to generate high wavebreak density (HWD) that corresponds to complex fractionated atrial electrograms (CFAEs). CF...

متن کاملTemporal Stability of Rotors and Atrial Activation Patterns in Persistent Human€Atrial Fibrillation
Fro Me xD Ad He Na Ca OBJECTIVES This study aimed to determine the spatiotemporal stability of rotors and other atrial activation patterns over 10 min in longstanding, persistent AF, along with the relationship of rotors to short cycle-length (CL) activity. BACKGROUND The prevalence, stability, and mechanistic importance of rotors in human atrial fibrillation (AF) remain unclear. METHODS Epicar...
متن کاملReview 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 کاملThree-dimensional dominant frequency mapping using autoregressive spectral analysis of atrial electrograms of patients in persistent atrial fibrillation
BACKGROUND Areas with high frequency activity within the atrium are thought to be 'drivers' of the rhythm in patients with atrial fibrillation (AF) and ablation of these areas seems to be an effective therapy in eliminating DF gradient and restoring sinus rhythm. Clinical groups have applied the traditional FFT-based approach to generate the three-dimensional dominant frequency (3D DF) maps dur...
