Graph convolutional regression of cardiac depolarization from sparse endocardial maps
Felix Meister, Tiziano Passerini, Chloé Audigier +6
Electroanatomic mapping as routinely acquired in ablation therapy of ventricular tachycardia is the gold standard method to identify the arrhythmogenic substrate. To reduce the acq…
Scale-Invariant Structures of Spiral Waves
Daniel Sohn, Konstantinos N. Aronis, Hiroshi Ashikaga
Spiral waves are considered to be one of the potential mechanisms that maintains complex arrhythmias such as atrial and ventricular fibrillation. The aim of the present study was t…
Causal Scale Shift Associated with Phase Transition to Human Atrial Fibrillation
Hiroshi Ashikaga, Konstantinos N. Aronis, Susumu Tao +1
An example of phase transition in natural complex systems is the qualitative and sudden change in the heart rhythm between sinus rhythm and atrial fibrillation (AF), the most commo…
Is Human Atrial Fibrillation Stochastic or Deterministic?
Konstantinos N. Aronis, Ronald D. Berger, Hugh Calkins +6
Atrial fibrillation (AF) is the most common cardiac arrhythmia in human beings, and is associated with significant morbidity and mortality. The current standard of care includes in…
Causal Unit of Rotors in a Cardiac System
Hiroshi Ashikaga, Francisco Prieto-Castrillo, Mari Kawakatsu +1
The heart exhibits complex systems behaviors during atrial fibrillation (AF), where the macroscopic collective behavior of the heart causes the microscopic behavior. However, the r…
Inter-Scale Information Flow as a Surrogate for Downward Causation That Maintains Spiral Waves
Hiroshi Ashikaga, Ryan G. James
The mechanism that maintains atrial fibrillation (AF) remains elusive. One approach to understanding and controlling the mechanism ("AF driver") is to quantify inter-scale informat…
Locating Order-Disorder Phase Transition in a Cardiac System
Hiroshi Ashikaga, Ameneh Asgari-Targhi
To prevent sudden cardiac death, predicting where in the cardiac system an order-disorder phase transition into ventricular fibrillation begins is as important as when it begins. W…
Hidden Structures of Information Transport Underlying Spiral Wave Dynamics
Hiroshi Ashikaga, Ryan G. James
A spiral wave is a macroscopic dynamic of excitable media that plays an important role in several distinct systems, including the Belousov-Zhabotinsky reaction, seizures in the bra…
Modeling the Heart as a Communication System
Hiroshi Ashikaga, José Aguilar-Rodríguez, Shai Gorsky +5
Electrical communication between cardiomyocytes can be perturbed during arrhythmia, but these perturbations are not captured by conventional electrocardiographic metrics. We develo…
