An Algorithm to Measure Beat-to-Beat Cycle Lengths for Assessment of Atrial Electrogram Rate and Regularity During Atrial Fibrillation

Autor: Jayakumar Sahadevan, Seungyup Lee, Dominique Durand, Albert L. Waldo, M B S Celeen Khrestian, Kyungmoo Ryu

Publikováno v: Journal of Cardiovascular Electrophysiology. 24:199-206

AF Cycle Length Detection Analysis. Introduction: Experimental models have demonstrated that atrial fibrillation (AF) may be due to one or more rapid drivers (source) producing AF. These drivers may be characterized by rapid and regular cycle lengths

Characterization of Atrial Activation (A-A) Intervals During Atrial Fibrillation Due to a Single Driver: Do They Reflect Atrial Effective Refractory Periods?

Publikováno v: Journal of Cardiovascular Electrophysiology. 22:310-315

Characterization of Atrial Activation Intervals During AF. Background: The mean, median, and minimum local atrial activation (A-A) intervals have been used to determine the local atrial effective refractory period (AERP) during atrial fibrillation (A

Frequency Analysis of Atrial Electrograms Identifies Conduction Pathways from the Left to the Right Atrium During Atrial Fibrillation-Studies in Two Canine Models

Autor: M B S Celeen Khrestian, Jayakumar Sahadevan, Kyungmoo Ryu, Albert L. Waldo, Bruce S. Stambler

Publikováno v: Journal of Cardiovascular Electrophysiology. 20:667-674

Studies of atrial fibrillation (AF) have demonstrated that a stable rhythm of very short cycle length in the left atrium (LA) can cause fibrillatory conduction in the rest of the atria. We tested the hypothesis that fast Fourier transform (FFT) analy

High density mapping of atrial fibrillation during vagal nerve stimulation in the canine heart: restudying the Moe hypothesis

Autor: Seungyup Lee, M B S Celeen Khrestian, Dominique Durand, Albert L. Waldo, Jayakumar Sahadevan

Publikováno v: Journal of cardiovascular electrophysiology. 24(3)

Mapping the Moe Model. Introduction: Moe et al. hypothesized that multiple wavelets (random reentry) were the mechanism of atrial fibrillation (AF) based on studies in a vagal nerve stimulation (VNS) canine model and a computer model of AF, but atria

Oral Vanoxerine Prevents Reinduction of Atrial Tachyarrhythmias: Preliminary Results

Autor: Ivan Cakulev, Albert L. Waldo, Kyungmoo Ryu, Arthur Brown, M B S Celeen Khrestian, Antonio E. Lacerda

Vanoxerine is a promising, new, investigational antiarrhythmic drug. The purpose of this study was to test the hypothesis that oral dosing of vanoxerine would first terminate induced atrial flutter (AFL) and atrial fibrillation (AF), and then prevent

Vanoxerine, a new drug for terminating atrial fibrillation and flutter

Autor: Antonio E. Lacerda, Naomichi Matsumoto, Kyungmoo Ryu, and Arthur M. Brown M.D., M B S Celeen Khrestian, Albert L. Waldo

Publikováno v: Journal of cardiovascular electrophysiology. 21(3)

Vanoxerine Terminates AF and AFL. Background: Vanoxerine produces potent block of cardiac hERG, sodium, and L-type calcium channels. Block is strongly frequency dependent, is unassociated with transmural dispersion of repolarization, and occurs at co

Use of fast fourier transform analysis of atrial electrograms for rapid characterization of atrial activation-implications for delineating possible mechanisms of atrial tachyarrhythmias

Autor: Bruce S. Stambler, Kyungmoo Ryu, M B S Celeen Khrestian, Albert L. Waldo, Jayakumar Sahadevan

Publikováno v: Journal of cardiovascular electrophysiology. 17(2)

Introduction: Different analysis techniques have been developed to help understand and characterize the mechanisms responsible for atrial arrhythmias. We tested the hypothesis that Fast Fourier Transform (FFT) analysis of recorded atrial electrograms
