Functional and morphological organization of the guinea-pig sinoatrial node compared with the rabbit sinoatrial node

, 1985
The primary pacemaker, i.e. the group of pacemaker cells discharging the sinoatrial node comprises less than 1000 cells in the guinea-pig and about 5000 cells in the rabbit.

Desmin is essential for the structure and function of the sinoatrial node; implications for increased arrhythmogenesis

, 2020
The sinoatrial node exhibits high amounts of desmin and desmoplakin, in structures we call “lateral intercalated discs”, connecting side by side adjacent cardiomyocytes. These structures are diminished in desmin deficient mouse model.

The pacemaker cell of the sinoatrial node of the rabbit

, 1978
Rabbit sinoatrial nodes were isolated and studied in an attempt to determine the cell of origin of the true pacemaker potential. Cells of the sinoatrial node of the rabbit giving rise to the characteristic true pacemaker potential were iontophoretically

The electrophysiological effects of Tongyang Huoxue granules on the ignition phase during hypoxia/reoxygenation injury in sinoatrial node cells

Frontiers in Physiology
IntroductionThis study was undertaken to explore the potential therapeutic effects of Tongyang Huoxue Granules (TYHX) on sinoatrial node (SAN) dysfunction, a cardiac disorder characterized by impaired impulse generation or conduction.

Preoperative secundum atrial septal defect with coexisting sinus node and atrioventricular node dysfunction.

, 1982
Sinus node dysfunction in patients after repair of the secundum atrial septal defect has been ascribed to surgical damage. We studied 15 consecutive patients with secundum atrial septal defect before operative intervention.

Coupling between two Resonant model sinoatrial node cells.

, 2019
A: Parameters of the action potential of sinoatrial node cell. MDP is a maximal diastolic potential, Vmax is the maximum potential, and VTh is the threshold potential. B: State controller of the Resonant model of a sinoatrial node cell.

Does Long-Term Sport Practice Facilitate the Development of Idiopathic Bradycardia Requiring Early Pacemaker Implantation During the Course of Life?

Journal of Cardiovascular Development and Disease
Background: Sinus bradycardia and first-/second-degree atrioventricular (AV) block in athletes are traditionally considered secondary to increased vagal tone and therefore reversible.

Atrial fibrillation, sinoatrial and atrioventricular node dysfunction in a mouse model of heart failure with preserved ejection fraction

Experimental Physiology
Millions of people are affected by atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF), two disorders frequently found simultaneously. However, the interrelationship between these intertwined disorders is poorly understood,
