Genetics of Inherited Arrhythmias in Children

Indian Pacing and Electrophysiology Journal, 2008
Over the past two decades, breakthroughs in basic science have revealed the genetic etiology for several inherited arrhythmias. Onset of arrhythmias often commences in childhood and adolescence.

Early Ventricular Arrhythmias Correlate with Adverse Outcome in Takotsubo Syndrome: Analysis of a Large Single-Center Database

Journal of Cardiovascular Development and Disease
Background: Takotsubo syndrome (TTS) is an acute cardiac condition characterized by transient left ventricular dysfunction. Although generally considered reversible, early arrhythmias are a dreaded complication and their prognostic significance remains ...

Sarcopenia index as a predictor of ventricular arrhythmia risk in patients with type 2 diabetes mellitus: a longitudinal study

Diabetology & Metabolic Syndrome
Objective The correlation between sarcopenia and diabetes mellitus (DM) holds considerable importance. The prognosis of ventricular arrhythmias in individuals with type 2 diabetes mellitus complicated by sarcopenia remains uncertain.

Potassium and ventricular arrhythmias

The American Journal of Cardiology, 1990
Potassium is a major determinant of the electrophysiologic properties of the myocardial membrane, and it plays an important role in the occurrence of arrhythmia. Hypokalemia has been associated with an increased frequency of ventricular premature complexes (VPCs) in some studies of hypertensive patients treated with diuretics, but other studies have ...

Genetic Implications of Fatty Tissue for the Development of Ventricular Arrhythmias

Cardiogenetics
Ventricular arrhythmias are a common disorder, and sometimes the etiology remains unclear. Present data support cardiac fatty tissue’s potential role as a substrate for ventricular arrhythmias.

Arrhythmic Risk in Elderly Patients Candidates to Transcatheter Aortic Valve Replacement: Predictive Role of Repolarization Temporal Dispersion

Frontiers in Physiology, 2019
Background/AimDegenerative 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

Echocardiography and cardiac arrhythmias

Hellenic Journal of Cardiology, 2018
Cardiac arrhythmias refer to any abnormality or disturbance in the normal activation sequence of the myocardium and may be indicative of structural heart disease and the cause of significant cardiovascular complications and sudden cardiac death.

Cardiac arrhythmias during long-duration spaceflights

Journal of Arrhythmia, 2014
Few studies have investigated cardiac arrhythmias during spaceflight. Atrial and ventricular premature contractions, short-duration atrial fibrillation, and non-sustained ventricular tachycardia were reported by previous spaceflight programs.

Ventricular unloading causes prolongation of the QT interval and induces ventricular arrhythmias in rat hearts

Frontiers in Physiology
IntroductionVentricular unloading during prolonged bed rest, mechanical circulatory support or microgravity has repeatedly been linked to potentially life-threatening arrhythmias.
