Nonlinear and stochastic dynamics in the heart
In a normal human life span, the heart beats about 2–3 billion times. Under diseased
conditions, a heart may lose its normal rhythm and degenerate suddenly into much faster …

Self-organization and the dynamical nature of ventricular fibrillation
This article reviews recent data supporting the conjecture that, in the structurally and
electrophysiologically normal heart, cardiac fibrillation is not a totally random phenomenon …

Nonlinear dynamics of heart rhythm disorders
A Karma, RF Gilmour - Physics Today, 2007 - pubs.aip.org
Cardiac arrhythmias are heart-rhythm disorders. Most arrhythmias are not life threatening,
and many are benign. But some rhythm disturbances originating in the ventricles—the …

[HTML][HTML] Cardiac arrhythmia
Cardiac arrhythmia is the condition in which the heart's normal rhythm is disrupted. In this
article, we describe the heart's normal sinus rhythm and a number of different types of …

Mechanisms of ventricular arrhythmias: a dynamical systems-based perspective
Defining the cellular electrophysiological mechanisms for ventricular tachyarrhythmias is
difficult, given the wide array of potential mechanisms, ranging from abnormal automaticity to …
