Overview

Requires wavelet dynamics knowledge for AF wavelength interpretation; leaves open clinical translation to human reentry management.

Structured PICO

P
Population
Biophysically based computer model of human atria
I
Intervention
Simulation of multiple re-entrant wavelets, different arrhythmogenic substrates, heterogeneities in refractoriness, and mother rotor
O
Outcome
Relationship between wavelength and AF perpetuation, and performance of different methods for wavelength estimation

Computer modeling demonstrates that accurate interpretation of cardiac wavelength in atrial fibrillation requires prior knowledge of the underlying wavelet dynamics.

Cite This Study

Jacquemet et al. (2005) studied Atrial fibrillation. Computer model of human atria was evaluated on Relationship between wavelength and AF perpetuation. A biophysically based computer model confirmed that cardiac wavelength must be below a critical value for atrial fibrillation to be sustained via multiple re-entrant wavelets.
