Mechanisms of Chronic Metabolic Stress in Arrhythmias

Antioxidants, 2020
Cardiac arrhythmias are responsible for many cardiovascular disease-related deaths worldwide. While arrhythmia pathogenesis is complex, there is increasing evidence for metabolic causes.

Arrhythmias in Chronic Kidney Disease

European Cardiology Review, 2022
Arrhythmias cause disability and an increased risk of premature death in the general population but far more so in patients with renal failure. The association between the cardiac and renal systems is complex and derives in part from common causality of ...

Moderator Band and Ventricular Tachycardia: Structural or Functional Substrate?

Journal of Cardiovascular Development and Disease, 2023
The moderator band (MB) is an intracavitary structure of the right ventricle composed of muscular fibers encompassing specialized Purkinje fibers, separated each other by collagen and adipose tissue.

Cardiovascular magnetic resonance guided electrophysiology studies

Journal of Cardiovascular Magnetic Resonance, 2009
Catheter ablation is a first line treatment for many cardiac arrhythmias and is generally performed under x-ray fluoroscopy guidance. However, current techniques for ablating complex arrhythmias such as atrial fibrillation and ventricular tachycardia are

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

Ictal asystole: a case presentation

BMC Neurology, 2018
Background Epileptic seizures can lead to cardiac arrhythmias. The arrhythmias may be in the form of tachycardia, bradycardia or asystole. Ictal bradycardia and asystole can lead to sudden unexpected death.

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Appropriate time interval to update ambiguous genetic diagnosis in inherited arrhythmogenic syndromes

iScience
Summary: Genetic analysis identified the cause of the disease in inherited arrhythmogenic syndromes. A clinically actionable genetic diagnosis requires an accurate interpretation following the current guidelines. Practically half of the genetic diagnoses

Research advances of arrhythmia in patients with chronic kidney disease

Linchuang shenzangbing zazhi, 2023
Cardiovascular disease is one of the leading causes of mortality in patients with chronic kidney disease (CKD). And arrhythmias is a predominant symptom. As compared with the general population, the etiology of arrhythmias is more complex and formulating

Complexity analysis of experimental cardiac arrhythmia [PDF]

2014 IEEE REGION 10 SYMPOSIUM, 2014
To study the cardiac arrhythmia, an in vitro experimental model and Multielectrodes Array (MEA) are used. This platform serves as an intermediary of the electrical activities of cardiac cells and the signal processing / dynamics analysis. Through it the extracellular potential of cardiac cells is acquired, allowing a real-time monitoring / analyzing ...
