Multiple Arrhythmogenic Substrate for Tachycardia in a Patient with Frequent Palpitations [PDF]

open access: yes, 2005
We report a 26-year-old woman with frequent episodes of palpitation and dizziness. Resting electrocardiography showed no evidence of ventricular preexcitation.

Implantable cardioverter defibrillators for the treatment of arrhythmias and cardiac resynchronisation therapy for the treatment of heart failure: systematic review and economic evaluation [PDF]

open access: yes, 2014
Background This assessment updates and expands on two previous technology assessments that evaluated implantable cardioverter defibrillators (ICDs) for arrhythmias and cardiac resynchronisation therapy (CRT) for heart failure (HF).

Mitochondrial Transplantation via Magnetically Responsive Artificial Cells Promotes Intracerebral Hemorrhage Recovery by Supporting Microglia Immunological Homeostasis

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A type of magnetically responsive artificial cells (ACs) has been developed, demonstrating the loading of mitochondria and self‐enclosure processes to ensure the protection of mitochondrial transport via the bloodstream. The treatment with ACs effectively transplanted mitochondria around the lesion, thereby improving neurological recovery by supporting

Left Bundle Branch Pacing in a Patient With Dextroposed Heart: A Case Report

open access: yesClinical Case Reports
The Right Ventricular (RV) apex has been the standard site for pacing in symptomatic bradyarrhythmias, but chronic RV pacing can cause adverse effects such as atrial arrhythmias and left ventricular dysfunction. Physiological pacing, including His bundle

Congenital and childhood atrioventricular blocks: pathophysiology and contemporary management [PDF]

open access: yes, 2016
Atrioventricular block is classified as congeni- tal if diagnosed in utero, at birth, or within the first month of life. The pathophysiological process is believed to be due to immune-mediated injury of the conduction system, which occurs as a result

Promoting Electrochemical Reactions with Dual‐Atom Catalysts for High‐Rate Lithium–Sulfur Batteries

open access: yesAdvanced Materials, EarlyView.
A scalable strategy for synthesizing transition metal–bismuth atomic pairs on carbon nitride to accelerate sulfur redox reactions in lithium–sulfur batteries is presented. Nickel‐bismuth and cobatl‐bismuth catalysts improve rate performance by promoting direct electrochemical transitions and rapid Li2S nucleation, minimizing sulfur loss, and enhancing ...

Manganese‐Based Spinel Cathodes: A Promising Frontier for Solid‐State Lithium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Mn‐based spinel cathodes LiMn2O4 (LMO) and LiNi0.5Mn1.5O4 (LNMO), with the unique characteristics of low cost, structural stability, and 3D Li‐ion diffusion channels, have presented great potential in all‐solid‐state batteries. Here, a comprehensive understanding and valuable insights into the rational design and implications for the future development

Recent Studies in the Pre-Excitation Syndrome [PDF]

open access: yes, 1973
The Wolff-Parkinson-White syndrome has held an unusual fascination for cardiologists ever since its original description in 1930. Over 60 different theories have been postulated to describe the mechanism of pre-excitation.
