Optoelectronic Interfaces for Nongenetic Modulation of Excitable Tissues
Small Methods, EarlyView.This review summarizes recent advances in nongenetic optoelectronic technologies for the modulation of excitable biotissues, covering material selection, device design, and working principles, as well as characterization methods. Representative applications in in vitro and in vivo models of the cardiac, central, and peripheral nervous systems are ...

A case report of sinoatrial arrest caused by temporal lobe epilepsy in subclinical glioblastoma
BMC Cardiovascular Disorders, 2020 Background Atrial fibrillation with symptomatic bradycardia, higher grade atrioventricular block, and sinus node disease are all common indications for permanent pacemaker implantation.

Atrial and Sinoatrial Node Development in the Zebrafish Heart
Journal of Cardiovascular Development and Disease, 2021 Proper development and function of the vertebrate heart is vital for embryonic and postnatal life. Many congenital heart defects in humans are associated with disruption of genes that direct the formation or maintenance of atrial and pacemaker ...

Isorhythmic atrioventricular dissociation during anaesthesia in a cat
Veterinary Record Case Reports, EarlyView.Abstract A 10‐year‐old, male, neutered domestic shorthair cat with suspected hypertrophic cardiomyopathy was referred for cystotomy to remove uroliths present in its urinary bladder. Fifteen minutes after induction of general anaesthesia, atrioventricular dissociation was noted on the electrocardiogram with similar atrial and ventricular firing rates ...

Computer Three-Dimensional Reconstruction of the Sinoatrial Node [PDF]
Circulation, 2005 Background— There is an effort to build an anatomically and biophysically detailed virtual heart, and, although there are models for the atria and ventricles, there is no model for the sinoatrial node (SAN).

Volume kinetics of lactated Ringer's solution in adult horses
Equine Veterinary Journal, EarlyView.Abstract Background Fluid therapy in horses is primarily empirical. Evidence‐based quantification of the disposition of intravenous (IV) crystalloids used in clinical practice could enhance the effectiveness of fluid therapy. Objectives To determine the pharmacokinetics (i.e., volume kinetics: VK) and associated haemodynamic effects of IV lactated ...

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).

The morphologic development of the sinoatrial node in the mouse
The American Journal of Cardiology, 1970 Abstract A plastic embedding technique was employed on mouse embryos after fixation with a gluteraldehyde-paraformaldehyde mixture and preparation of large, 1 to 2 μ sections cut on a rotary microtome with steel knives. It was then possible to trace the sinoatrial node back to mouse embryos of 4 sol1 2 mm crown-rump length ( 10 1 2 days

The Calcium and Voltage Clocks in Sinoatrial Node Automaticity [PDF]
Korean Circulation Journal, 2009 Recent evidence indicates that the voltage (cyclic activation and deactivation of membrane ion channels) and Ca(2+) clocks (rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release) jointly regulate sinoatrial node (SAN) automaticity. Since the intact SAN is a heterogeneous structure that includes multiple different cell types interacting with each ...

Atrial Arrhythmias in Cardiac Sarcoidosis—Case Presentation and Systematic Review
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Sarcoidosis is a rare idiopathic, multiorgan disease with clinical cardiac involvement in approximately 5% of cases. Diagnosis and management of cardiac sarcoidosis (CS) have mainly focused on impaired LV function, ventricular arrhythmias, and atrio‐ventricular conduction disease.
