Can we use verbal estimation to dissect the internal clock? Differentiating the effects of pacemaker rate, switch latencies, and judgment processes [PDF]

, 2010
Behavioural timing is frequently assumed to be based on the accumulation of pulses from a pacemaker. In humans, verbal estimation is often used to determine whether the effect of factors which influence subjective time become more pronounced at longer ...

Correlation of aortic valve annular plane assessment by on‐table three‐dimensional rotational angiography and preprocedural computed tomography

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1316-1322, December 1, 2022., 2022
Abstract Objectives To assess the correlation between the aortic valve annular plane (AVAP) obtained by preprocedural computed tomography (CT) with on‐table three‐dimensional rotational angiography (3DRA), in patients undergoing transcatheter aortic valve replacement (TAVR).

Extracting topological features from dynamical measures in networks of Kuramoto oscillators [PDF]

, 2012
The Kuramoto model for an ensemble of coupled oscillators provides a paradigmatic example of non-equilibrium transitions between an incoherent and a synchronized state.

Heteroclinic units acting as pacemakers: Entrained dynamics for cognitive processes [PDF]

arXiv, 2021
Heteroclinic dynamics is a suitable framework for describing transient and reproducible dynamics such as cognitive processes in the brain. We demonstrate how heteroclinic units can act as pacemakers to entrain larger sets of units from a resting state to hierarchical heteroclinic motion that is able to describe fast oscillations modulated by slow ...

Transient complete heart block following catheter ablation of a left lateral accessory pathway. [PDF]

, 2019
A 16-year-old female with symptomatic Wolff-Parkinson-White (WPW) syndrome underwent catheter ablation of a left-sided lateral accessory pathway. The accessory pathway was eliminated with the first ablation lesion; however, the patient immediately ...

A case of dual atrioventricular nodal nonreentrant tachycardia: An unusual cause of tachycardia-induced cardiomyopathy

Journal of Arrhythmia, 2015
We report on a 45-year-old female who developed cardiomyopathy due to incessant dual atrioventricular nodal nonreentrant tachycardia. Her condition was completely resolved by performing radiofrequency ablation of the slow pathway.

Reentrant Synchronization and Pattern Formation in Pacemaker-Entrained Kuramoto Oscillators [PDF]

Phys. Rev. E 74, 026203 (2006), 2006
We study phase entrainment of Kuramoto oscillators under different conditions on the interaction range and the natural frequencies. In the first part the oscillators are entrained by a pacemaker acting like an impurity or a defect. We analytically derive the entrainment frequency for arbitrary interaction range and the entrainment threshold for all-to ...

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 ...

QT and Tpeak‐Tend interval variability: Predictive electrical markers of hospital stay length and mortality in acute decompensated heart failure. Preliminary data

Clinical Cardiology, Volume 45, Issue 12, Page 1192-1198, December 2022., 2022
Abstract Background As previously reported, an increased repolarization temporal imbalance induces a higher risk of total/cardiovascular mortality. Hypothesis The aim of this study was to assess if the electrocardiographic short period markers of repolarization temporal dispersion could be predictive of the hospital stay length and mortality in ...
