Target patterns and pacemakers in reaction-diffusion systems

open access: yes, 2003
Pattern formation in systems far from thermal equilibrium is a fascinating phenomenon. Reaction-diffusion systems are an important type of system where pattern formation is observed.

Intracardiac turbines suitable for catheter-based implantation - an approach to power battery- and leadless cardiac pacemakers?

open access: yes, 2020
OBJECTIVE Cardiac pacemakers are powered by batteries, which become exhausted after a few years. This is a problem in particular for leadless pacemakers since they are difficult to explant.

Same‐Day Discharge After Transcatheter Aortic Valve Implantation: Who, When, and How?

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The burden of severe aortic stenosis requiring treatment is growing due to ageing populations. This places increased demands on health resources due to the growing number of transcatheter aortic valve implantation (TAVI) procedures and hospital bed occupancy.

Bioinspired Flexible and Stretchable Coil Structure from Ti3C2Tx MXene/AgNPs‐Functionalized Piezoelectric Nanofibers for Enhanced Energy Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ti3C2Tx MXene and Ag nanoparticles are embedded into piezoelectric nanofibers to form a stretchable, self‐powered coil that converts mechanical deformation into electrical energy. The device enables controllable power output during stretching and release while maintaining a compact and lightweight architecture, making it suitable for miniaturized ...

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

INFECTION ASSOCIATED WITH THE IMPLANTATION OF CARDIOVASCULAR IMPLANTABLE ELECTRONIC DEVICES

open access: yesАрхивъ внутренней медицины, 2017
Data on the frequency, nature, risk factors and diagnosis of infectious complications (IC) in patients with cardioimplanted electronic devices (CED) — artificial rhythm drivers, cardiodefibrillators, devices for cardiosynchronizing therapy — often ...

Differential sensitivity of cardiac pacemakers to exogenous adenosine in vivo

open access: yes, 1990
Adenosine exerts pronounced depressant effects on cardiac pacemakers. Previous studies in vitro have indicated that different pacemakers exhibit variable sensitivity to adenosine: ventricular greater than junctional greater than sinus node pacemakers ...
