Itraconazole-induced Torsade de Pointes in a patient receiving methadone substitution therapy [PDF]

, 2009
Issues. Methadone, a pharmacological agent used to treat heroin dependence is relatively safe, but may cause cardiac arrhythmias in the concurrent presence of other risk factors. Approach and Key Findings.

Topological constraints on spiral wave dynamics in spherical geometries with inhomogeneous excitability [PDF]

, 2004
We analyze the way topological constraints and inhomogeneity in the excitability influence the dynamics of spiral waves on spheres and punctured spheres of excitable media. We generalize the definition of an index such that it characterizes not only each

Reprogramming the Myocardial Infarction Conductive Microenvironment with Superconductive Ionic Patch for Cardiac Function Repair

Advanced Science, EarlyView.
A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...

Local impedance and contact force guidance to predict successful cavotricuspid isthmus ablation with a zero-fluoroscopy approach

Frontiers in Cardiovascular Medicine
IntroductionA new technology capable of monitoring local impedance (LI) and contact force (CF) has recently been developed. At the same time, there is growing concern regarding catheter ablation performed under fluoroscopy guidance, due to its harmful ...

Effect of myocyte-fibroblast coupling on the onset of pathological dynamics in a model of ventricular tissue [PDF]

, 2017
Managing lethal cardiac arrhythmias is one of the biggest challenges in modern cardiology, and hence it is very important to understand the factors underlying such arrhythmias.

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

Advanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.

Fever Unmasked Brugada Syndrome in Pediatric Patient: A Case Report [PDF]

, 2020
Introduction: Brugada syndrome is an arrhythmogenic disorder that is a known cause of sudden cardiac death. It is characterized by a pattern of ST segment elevation in the precordial leads on an electrocardiogram (EKG) due to a sodium channelopathy.Case ...

A comparative study of early afterdepolarization-mediated fibrillation in two mathematical models for human ventricular cells [PDF]

, 2015
Early afterdepolarizations (EADs), which are abnormal oscillations of the membrane potential at the plateau phase of an action potential, are implicated in the development of cardiac arrhythmias like Torsade de Pointes.
