Use of machine learning and Poincaré density grid in the diagnosis of sinus node dysfunction caused by sinoatrial conduction block in dogs [PDF]
Journal of Veterinary Internal MedicineBackground Sinus node dysfunction because of abnormal impulse generation or sinoatrial conduction block causes bradycardia that can be difficult to differentiate from high parasympathetic/low sympathetic modulation (HP/LSM).

RyR2(R4496C) Expression Induces Sinoatrial Node Dysfunction [PDF]
Biophysical Journal, 2011 Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) is an arrhythmogenic disease characterized by stress-triggered syncope and sudden death. While ventricular tachycardia appears only during stress conditions, CPVT patients manifest basal sino-atrial node (SAN) dysfunction, but the underlying mechanism remains unknown.

The genetic basis for inherited forms of sinoatrial dysfunction and atrioventricular node dysfunction [PDF]
Journal of Interventional Cardiac Electrophysiology, 2015 The sinoatrial node (SAN) and the atrioventricular node (AVN) are the anatomical and functional regions of the heart which play critical roles in the generation and conduction of the electrical impulse. Their functions are ensured by peculiar structural cytological properties and specific collections of ion channels.

Mitochondrial dysfunction is a key link involved in the pathogenesis of sick sinus syndrome: a review [PDF]
Frontiers in Cardiovascular MedicineSick sinus syndrome (SSS) is a grave medical condition that can precipitate sudden death. The pathogenesis of SSS remains incompletely understood. Existing research postulates that the fundamental mechanism involves increased fibrosis of the sinoatrial ...

Staged operation to fontan increases the incidence of sinoatrial node dysfunction [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 1996 Morbidity and mortality of total cavopulmonary connection (modified Fontan procedure) may be decreased in many patients with single ventricle in whom the risk of surgery is high by performing the operations in a staged fashion. Each operative intervention, however, exposes the sinoatrial node region to risk of injury, and a multistaged approach may ...

Changes in Ion Channel Gene Expression Underlying Heart Failure-Induced Sinoatrial Node Dysfunction [PDF]
Circulation: Heart Failure, 2011 Background— Heart failure (HF) causes a decline in the function of the pacemaker of the heart—the sinoatrial node (SAN). The aim of the study was to investigate HF-induced changes in the expression of the ion channels and related proteins underlying the pacemaker activity of the SAN.

Sinus Node Dysfunction and Atrial Fibrillation Associatedwith Isolated Sinoatrial Node Artery Ectasia [PDF]
Electronic Journal of General Medicine, 2013 A 74 year-old female patient was admitted to emergency service with a complaints of dizziness and shortness of breath. Complete atrioventricular block was observed and patient was followed up two days with transient transvenous cardiac pacemaker. Afterthat, atrial fibrillation (AF) was progressed and then, coronary angiography was scheduled.
