Experimental Physiology, EarlyView.Summary of the timeline of characterized events related to atrial fibrilation (AF) and diastolic dysfunction in a mouse heart failure with preserved ejection fraction (HFpEF) model. Three weeks after the initiation of the diet regimen with high fat diet (HFD) and Nω‐nitro‐l‐arginine methyl ester (l‐NAME) in drinking water to induce HFpEF, significantly

Is sodium current present in human sinoatrial node cells?
International Journal of Biological Sciences, 2009 Pacemaker activity of the sinoatrial node has been studied extensively in various animal species, but is virtually unexplored in man. As such, it is unknown whether the fast sodium current (INa) plays a role in the pacemaker activity of the human ...

Phase response characteristics of sinoatrial node cells
Computers in Biology and Medicine, 2007 In this work, the dynamic response of the sinoatrial node (SAN), the natural pacemaker of the heart, to short external stimuli is investigated using the Zhang et al. model. The model equations are solved twice for the central cell and for the peripheral cell.

Experimental Physiology, EarlyView.Abstract The leading cause of epilepsy‐related mortality is sudden unexpected death in epilepsy (SUDEP), resulting from seizure‐induced cardiorespiratory arrest by mechanisms that remain unresolved. Mutations in ion channel genes expressed in both brain and heart represent SUDEP risk factors because they can disrupt neural and cardiac rhythms ...

Acute Isolation of Cells from Murine Sino-atrial Node
Bio-Protocol, 2020 The cardiac conduction system allows the synchronized propagation of electrical activity through heart muscle. This is initiated by the spontaneous activity of the specialized pacemaker cells of the sino-atrial node (SAN).

Metabolic syndrome remodels electrical activity of the sinoatrial node and produces arrhythmias in rats. [PDF]
PLoS ONE, 2013 In the last ten years, the incidences of metabolic syndrome and supraventricular arrhythmias have greatly increased. The metabolic syndrome is a cluster of alterations, which include obesity, hypertension, hypertriglyceridemia, glucose intolerance and ...

Effects of the network structural properties on its controllability
, 2007 In a recent paper, it has been suggested that the controllability of a diffusively coupled complex network, subject to localized feedback loops at some of its vertices, can be assessed by means of a Master Stability Function approach, where the network ...

A new algorithm to diagnose atrial ectopic origin from multi lead ECG systems - insights from 3D virtual human atria and torso [PDF]
, 2015 Rapid atrial arrhythmias such as atrial fibrillation (AF) predispose to ventricular arrhythmias, sudden cardiac death and stroke. Identifying the origin of atrial ectopic activity from the electrocardiogram (ECG) can help to diagnose the early onset of ...

Glial cells in the heart: Implications for their roles in health and disease
The Journal of Physiology, EarlyView.Abstract figure legend Schematic representation of cardiac autonomic ganglia within epicardial fat pads (posterior heart surface shown), containing vagal postganglionic neuron cell bodies, associated fibres, and glia. These ganglia receive cholinergic input from vagal preganglionic neurons and adrenergic input from sympathetic postganglionic neurons ...
