Single beat determination of intraventricular systolic dyssynchrony in paitents with atrial fibrillation and systolic dysfunction [PDF]

open access: yes, 2013
Background:: Atrial fibrillation (AF) is the most common clinically significant cardiac arrhythmia. However, diagnosis of intraventricular dyssynchrony in patients with AF is difficult due to beat-to-beat variation. Additionally, evaluation of mechanical

Following one's heart: cardiac rhythms gate central initiation of sympathetic reflexes [PDF]

open access: yes, 2009
Central nervous processing of environmental stimuli requires integration of sensory information with ongoing autonomic control of cardiovascular function.

Filament tension and phase-locked drift of meandering scroll waves [PDF]

open access: yes, 2011
Rotating scroll waves are self-organising patterns which are found in many oscillating or excitable systems. Here we show that quasi-periodic (meandering) scroll waves, which include the rotors that organise cardiac arrhythmias, exhibit filament tension ...

Plasma N-Terminal Pro-Brain Natriuretic Peptide as Prognostic Marker in Fatal Cardial Decompensation with Sunitinib Malate Therapy [PDF]

open access: yes, 2010
A 74-year-old man with metastatic renal cell carcinoma and a history of cardiac failure was treated with sunitinib malate. MUGA echocardiography could not detect a relevant change in the ejection fraction although the clinical situation of the patient ...

Patient-specific CFD simulation of intraventricular haemodynamics based on 3D ultrasound imaging [PDF]

open access: yes, 2016
Background: The goal of this paper is to present a computational fluid dynamic (CFD) model with moving boundaries to study the intraventricular flows in a patient-specific framework.

Segmentation of the left ventricle of the heart in 3-D+t MRI data using an optimized nonrigid temporal model [PDF]

open access: yes, 2008
Modern medical imaging modalities provide large amounts of information in both the spatial and temporal domains and the incorporation of this information in a coherent algorithmic framework is a significant challenge.

Distinct effects of inflammation on preconditioning and regeneration of the adult zebrafish heart [PDF]

open access: yes, 2016
The adult heart is able to activate cardioprotective programmes and modifies its architecture in response to physiological or pathological changes. While mammalian cardiac remodelling often involves hypertrophic expansion, the adult zebrafish heart ...

Risk stratifiers for arrhythmic and non-arrhythmic mortality after acute myocardial infarction [PDF]

open access: yes, 2018
Open Access. Publicado online: 2-Jul-2018The effective discrimination between patients at risk of Arrhythmic Mortality (AM) and Non-Arrhythmic Mortality (NAM) constitutes one of the important unmet clinical needs.

Cyclic changes of blood echogenicity in high-frequency ultrasound [PDF]

open access: yes, 1991
Ultrasound images from human arteries obtained in vivo with an intravascular 30 MHz ultrasound imaging device show that blood echogenicity changes during the cardiac cycle.

Interactions between cardiac activity and conscious somatosensory perception

open access: yes, 2019
Fluctuations in the heart's activity can modulate the access of external stimuli to consciousness. The link between perceptual awareness and cardiac signals has been investigated mainly in the visual and auditory domain. Here, we investigated whether the
