Complex patterns of spontaneous initiations and terminations of reentrant circulation in a loop of cardiac tissue

, 2008
A two-component model is developed that consists of a discrete loop of cardiac cells that circulates action potentials together with a cardiac pacing mechanism.

Nonlinear physics of electrical wave propagation in the heart: a review [PDF]

, 2016
The beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over the atria and the ventricles ...

Cardiac involvement in rheumatoid arthritis

Reumatismo, 2011
Rheumatoid arthritis (RA) is a systemic disease of unknown etiology characterized by a chronic inflammatory process mainly leading to destruction of synovial membrane of small and major diarthrodial joints.

Ion channels: structural basis for function and disease. [PDF]

, 1996
Ion channels are ubiquitous proteins that mediate nervous and muscular function, rapid transmembrane signaling events, and ionic and fluid balance. The cloning of genes encoding ion channels has led to major strides in understanding the mechanistic basis

A Case Report of Systemic Sclerosis Complicated by Biventricular Heart Failure, Pulmonary Hypertension and Review of Literature [PDF]

, 2017
Background: Systemic sclerosis (SSc) is an autoimmune connective tissue disorder whose aetiology is not fully understood. Skin fibrosis and visceral organs involvement are the hallmarks, and the heart could be disproportionately or subtly involved ...

Novel PRKAG2 Mutation Responsible for the Genetic Syndrome of Ventricular Preexcitation and Conduction System Disease With Childhood Onset and Absence of Cardiac Hypertrophy [PDF]

Circulation, 2001
Background — We recently reported a mutation in the PRKAG2 gene to be responsible for a familial syndrome of ventricular preexcitation, atrial fibrillation, conduction defects, and cardiac hypertrophy. We now report

Conduction defects and arrhythmias in mdx mice are not associated with a degeneration of the cardiac Purkinje network

Frontiers in Physiology
Duchenne muscular dystrophy (DMD) is a severe X-chromosomal disease characterised by progressive muscle weakness and degeneration. Cardiac involvement is inevitable in DMD patients and ventricular arrhythmias are a high-risk factor for mortality in these

Numerical simulation of electrocardiograms for full cardiac cycles in healthy and pathological conditions [PDF]

, 2015
This work is dedicated to the simulation of full cycles of the electrical activity of the heart and the corresponding body surface potential. The model is based on a realistic torso and heart anatomy, including ventricles and atria.
