Entrainment of randomly coupled oscillator networks by a pacemaker [PDF]

, 2004
Entrainment by a pacemaker, representing an element with a higher frequency, is numerically investigated for several classes of random networks which consist of identical phase oscillators.

The relationship of myocardial collagen metabolism and reverse remodeling after cardiac resynchronization therapy [PDF]

Journal of Medical Biochemistry, 2016
Background: In the majority of patients with a wide QRS complex and heart failure resistant to optimal medical therapy, cardiac resynchronization therapy (CRT) leads to reverse ventricular remodeling and possibly to changes in cardiac collagen synthesis ...

How do changes in speed affect the perception of duration? [PDF]

, 2011
Six experiments investigated how changes in stimulus speed influence subjective duration. Participants saw rotating or translating shapes in three conditions: constant speed, accelerating motion, and decelerating motion.

Impact of Leadless Pacemaker Therapy on Cardiac and Atrioventricular Valve Function Through 12 Months of Follow-Up.

Circulation: Arrhythmia and Electrophysiology, 2019
BACKGROUND Endocardial pacemaker leads and right ventricular (RV) pacing are well-known causes of tricuspid valve, mitral valve, and cardiac dysfunction. Lead-related adverse consequences can potentially be mitigated by leadless pacemaker (LP) therapy by

Leadless pacemaker implant in patients with pre‐existing infections: Results from the Micra postapproval registry

Cardiovascular Electrophysiology, 2019
Leadless pacemakers may provide a safe and attractive pacing option to patients with cardiac implantable electronic device (CIED) infection. We describe the characteristics and outcomes of patients with a recent CIED infection undergoing Micra implant ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Left bundle branch area pacing optimized cardiac resynchronization – a promise of way better?

Cardiologia Hungarica
Conduction system pacing may revolutionize conventional pacemaker therapy. Both His- and left bundle branch area pacing (LBBAP) can prevent right ventricular pacing induced cardiomyopathy in bradycardia pacemaker indications, furtheron they might improve

Downregulated lncRNA RCPCD promotes differentiation of embryonic stem cells into cardiac pacemaker-like cells by suppressing HCN4 promoter methylation

Cell Death and Disease, 2021
Long non-coding RNA (lncRNA) is receiving increasing attention in embryonic stem cells (ESCs) research. However, the roles of lncRNA in the differentiation of ESCs into pacemaker-like cells are still unclear.

‘Twiddling’ of the pacemaker resulting in lead dislodgement [PDF]

, 2009
Twiddler’s syndrome is a rare condition in which patient manipulation of the pulse generator within its pocket may result in coiling of the lead and lead dislodgement, thereby causing pacemaker malfunction.
