Understanding and Interpreting Dominant Frequency Analysis of AF Electrograms

Journal of Cardiovascular Electrophysiology, 2007
Dominant frequency analysis of atrial electrograms has been used to understand the pathophysiology of atrial fibrillation (AF). Although dominant frequency is an effective tool to estimate activation rate during AF, other factors besides activation rate ...

Comparison of dominant frequency attenuation of blasting vibration for different charge structures

Journal of Rock Mechanics and Geotechnical Engineering, 2022
Dominant frequency attenuation is a significant concern for frequency-based criteria of blasting vibration control. It is necessary to develop a concise and practical prediction equation describing dominant frequency attenuation.

Technical Considerations for Dominant Frequency Analysis

Journal of Cardiovascular Electrophysiology, 2007
Introduction: Dominant frequency (DF) analysis of atrial electrograms has been used to characterize atrial fibrillation (AF). The aim of this study was to explore technical issues that may affect the estimation of local activation rate during AF using DF analysis. Methods and Results: Epicardial atrial electrograms recorded during AF from 10 dogs were

Abstract 17011: Correlation of Surface Atrial ECG Dominant Frequency to Intracardiac Atrial Electrogram Dominant Frequency

Circulation, 2023
Background: The surface Atrial ECG (A-ECG) is an underused tool in persistent atrial fibrillation (PeAF) that can provide dominant frequency (DF) of atrial activation. The association between A-ECG DF and left (LA) and right atrial (RA) DF has not been established. Research Question:

Achieving diagonal dominance by frequency interpolation

Proceedings of the 2004 American Control Conference, 2004
This paper proposes a new method for systematic construction of dynamic pre-compensators to achieve better diagonal dominance. Curve fitting is used to construct a dynamic pre-compensator element-by-element, meaning unlike most minimization algorithms, there is no restriction on the structure of each element.

Low Spatial Frequencies Dominate Apparent Motion

Perception, 1983
Experiments are reported which have been designed to establish what features of a pair of figures can be used as an input for apparent motion. The display consisted of a central figure, A, which appeared briefly and was followed immediately afterwards by two figures, B and C, which appeared on either side of the original location of A.
