Dynamics of conduction blocks in a model of paced cardiac tissue [PDF]

, 2005
We study numerically the dynamics of conduction blocks using a detailed electrophysiological model. We find that this dynamics depends critically on the size of the paced region.

Engineering a Human‐Sized Common Bile Duct Prototype with Regenerative Potential: In Vitro Evaluation of Mechanics, Function, Degradation, and Immune Modulation

Advanced Healthcare Materials, EarlyView.
This study presents a multiphasic bile duct construct composed of biocompatible materials and cells, featuring an inner layer that supports biliary epithelium growth, a middle layer providing mechanical strength, and an outer cell‐permissive layer designed to support future in vivo integration.

Universal Method of Compatibility Assessment for Novel Ablation Technologies With Different 3D Navigation Systems

Frontiers in Cardiovascular Medicine, 2022
BackgroundNew technologies for ablation procedures are often produced by different companies with no cross-compatibility out of the box. This is not a negligible clinical problem since those separately developed devices are often used together.

The effects of right ventricular apical pacing on left ventricular function. Stimulation of the right ventricular apex: should it still be the gold standard? [PDF]

, 2003
Current pacing practice is undergoing continuous and substantial changes. Initially pacing had an exclusively palliative role, since it was reserved for patients developing complete heart block or severe symptomatic bradycardia.

Cardiac arrhythmias and pacing [PDF]

Srce i krvni sudovi, 2012
In the last two years, a number of land-mark clinical trials have been published which further our understanding and clinical management of patients with atrial fibrillation (AF). Two of the major goals in the treatment of this condition include reducing pro-gression or recurrence of the arrhythmia and decrea-sing the risk of cardiovascular events ...

Long‐Term Outcomes of Pulmonary Vein Isolation in Patients With Brugada Syndrome and Paroxysmal Atrial Fibrillation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Pharmacological treatment of atrial fibrillation (AF) in the setting of Brugada syndrome (BrS) is challenging. In addition, patients with BrS with an implantable cardioverter‐defibrillator (ICD) might experience inappropriate shocks for fast ...

Devices for Prevention of Atrial Tachyarrhythmias [PDF]

, 2004
Atrial fibrillation (AF) is the most frequent sustained cardiac arrhythmia in clinical practice and, although its importance has been underestimated even in recent years, we are now becoming aware of its clinical transcendence1,2,3.

Single Nanocrown Electrodes for High‐Quality Intracellular Recording of Cardiomyocytes

Advanced Materials Interfaces, EarlyView.
Intracellular recording devices featuring 1‐, 3‐, 5‐, and 9‐nanocrown electrode arrays (NcEAs) per channel, along with alternative electrode geometries, are developed. Comparative analysis shows that single NcEAs provide high‐fidelity intracellular action potentials, while multi‐nanocrown and non‐vertical electrodes yield distorted signals, emphasizing
