The aim of the study was to develop a three-dimensional (3D) anatomically-detailed model of the rabbit right atrium containing the sinoatrial and atrioventricular nodes to study the electrophysiology of the nodes. A model was generated based on 3D images

Cellular and molecular landscape of mammalian sinoatrial node revealed by single-cell RNA sequencing
The spontaneous bioelectrical activity of pacemaker cells in sinoatrial node (SAN) triggers the heartbeats. Here, the authors perform single-cell RNA sequencing in the mouse SAN and identify molecular and cellular features of the SAN conserved in rabbit ...

Mathematical Models of Cardiac Pacemaking Function
Over the past half century, there has been intense and fruitful interaction between experimental and computational investigations of cardiac function. This interaction has, for example, led to deep understanding of cardiac excitation-contraction coupling;

Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Tachy-bradycardia syndrome (TBS) has been reported rarely in the fetus. We present here an unusual dominant involvement of sinoatrial node in a fetus presenting with TBS of anti-Sjögren'syndrome-related antigen A (SS-A) and antigen B (SS-B ...

Abstract The integration of modern systemic therapies with radiotherapy (RT) represents a promising strategy in breast cancer management, enhancing both locoregional control and systemic disease outcomes. This expert consensus from the Institut Curie Breast Radiotherapy Group focuses exclusively on modern systemic agents, synthesizing current evidence ...

Summary: Sinoatrial node (SAN) disease mechanisms are poorly understood, and therapeutic options are limited. Natriuretic peptide(s) (NP) are cardioprotective hormones whose effects can be mediated partly by the NP receptor C (NPR-C). We investigated the

Modulated parasystole originating in the sinoatrial node. [PDF]
A computer model of "modulated sinus parasystole" was devised in which two sinus pacemakers interacted electrotonically, entraining each other's periodicity according to their beat-to-beat phasic relationships. Depending on the preestablished rules, the model gave rise to various rhythm patterns that were similar to those recorded in patients with ...

Abstract Objectives Pediatric intestinal pseudo‐obstruction (PIPO) is a rare, heterogeneous, and severe gut motility disorder. In 2014, Chetaille et al. described chronic atrial and intestinal dysrhythmia (CAID) syndrome associated with a recessive SGO1 mutation (p.Lys23Glu) linking it to both intestinal pseudo‐obstruction and cardiac dysrhythmia. This
