PRRX1 Loss‐of‐Function Mutations Underlying Familial Atrial Fibrillation
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021 Background Atrial fibrillation (AF) is the most common form of clinical cardiac dysrhythmia responsible for thromboembolic cerebral stroke, congestive heart failure, and death. Aggregating evidence highlights the strong genetic basis of AF. Nevertheless,

Arrhythmic risk in elderly patients candidates to transcatheter aortic valve replacement. predicative role of repolarization temporal dispersion [PDF]
, 2019 Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities ...

Global alternans instability and its effect on non-linear wave propagation : dynamical Wenckebach block and self terminating spiral waves [PDF]
, 2016 The main mechanism of formation of reentrant cardiac arrhythmias is via formation of waveblocks at heterogeneities of cardiac tissue. We report that heterogeneity and the area of waveblock can extend itself in space and can result formation of new ...

Kathmandu University Medical Journal, 2020 Arrhythmias are seldom observed in the newborn period and rarely lead to serious consequences. Because they may be a continuation of fetal arrhythmias, newborn arrhythmias are different from those occurring at later ages. Here we describe a case of a newborn presented with tachycardia at birth.

Management of Arrhythmias in Cardiac Amyloidosis.
JACC Clinical Electrophysiology, 2020 Cardiac amyloidosis is characterized by extracellular protein fibril deposition in the myocardium leading to restrictive heart failure. Both atrial and ventricular arrhythmias, along with conduction disease, are common in cardiac amyloidosis, and are ...

Regulation of gap junction function; the role of nitric oxide. [PDF]
, 2013 Myocardial ischemia resulting from sudden occlusion of a coronary artery is one of the major causes in the appearance of severe, often life-threatening ventricular arrhythmias.
