Improved frequency resolution for characterization of complex fractionated atrial electrograms
BACKGROUND The dominant frequency of the Fourier power spectrum is useful to analyze complex fractionated atrial electrograms (CFAE), but spectral resolution is limited and uniform from DC to the Nyquist frequency. Herein the spectral resolution of a recently described and relatively new spectral estimation technique is compared to the Fourier radix-2 implementation. METHODS In 10 paroxysmal ...
متن کاملFrequency domain versus time domain methods in system identification
For some reason I now forget, Keith Glover and I were asked to prepare a discussion paper on frequency and time domain methods in system identi cation by the organizers of the IFAC symposium on System Identi cation in Darmstadt 1979. I visited Keith in Cambridge in April 1979 to prepare our paper. It later evolved into an Automatica arcticle. Since then, there has been a useful development of s...
متن کاملTime- and frequency-domain characteristics of atrial electrograms during sinus rhythm and atrial fibrillation.
BACKGROUND Complex fractionated atrial electrograms (CFAE) have been considered to be helpful during catheter ablation of atrial fibrillation (AF). The purpose of this study was to analyze the characteristics of CFAEs recorded during sinus rhythm (SR) and AF, and to determine their relationship to perpetuation of AF and clinical outcome. METHODS AND RESULTS Antral pulmonary vein isolation (AP...
متن کاملConnexin and fibrosis related microRNAs in complex fractionated atrial electrograms
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. There are two main factors facilitating the formation and persistence of AF: enhanced automaticity in some rapidly depolarizing foci and abnormal conduction substrates [1]. Fractionated or fragmented electrograms during AF were initially reported by Konings et al. [2] Then, other authors d...
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...
