Ajmaline attenuates electrocardiogram characteristics of inferolateral early repolarization.

, 2012
J waves are the hallmark of both inferolateral early repolarization (ER) and Brugada syndrome. While ajmaline, a class 1a antiarrhythmic drug, accentuates the J wave in Brugada syndrome, its effect on ER is unreported.Journal Articleinfo:eu-repo ...

Repolarization dispersion in patients with systemic sclerosis

, 2020
OBJECTIVE: Systemic sclerosis (SSc) is associated with increased cardiac morbidity and mortality. Whether some electrocardiographic markers of arrhythmias predispose to early cardiogenic death in SSc remains controversial.

Out-of-Hospital Cardiac Arrest Due to a Concealed Diagnosis

JACC: Case Reports, 2019
This case outlines the dynamic and often concealed electrocardiographic findings associated with Brugada syndrome and explores its important relationship with early repolarization syndrome as part of a spectrum of inherited J-wave syndromes.

A Heterozygous Missense hERG Mutation Associated with Early Repolarization Syndrome

Cellular Physiology and Biochemistry, 2018
Background/Aims: Early repolarization syndrome (ERS) has been recently recognized as early repolarization pattern with idiopathic ventricular fibrillation. However, the genetic background of ERS has not been fully understood.

Heritability of Early Repolarization [PDF]

Circulation: Cardiovascular Genetics, 2011
Background— Early repolarization (ER), defined by J-point elevation in 12-lead ECG, was recently associated with increased risk for idiopathic ventricular fibrillation and cardiovascular mortality. The determinants of ER are unknown. We investigated its heritability in a large, family-based cohort.

Association of indicators of arterial rigidity and arrithmogenesis in Novosibirsk men population

Атеросклероз, 2020
Pulse wave amplification and augmentation are considered as new indicators of arterial stiffness. It is of interest to study their association with electrocardiographic pro-arrhythmic patterns in the male population of Novosibirsk.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

Advanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...
