Autopsy findings in cases of fatal COVID‐19 vaccine‐induced myocarditis
Abstract COVID‐19 vaccines have been linked to myocarditis, which, in some circumstances, can be fatal. This systematic review aims to investigate potential causal links between COVID‐19 vaccines and death from myocarditis using post‐mortem analysis.

ADENYLYL CYCLASE TYPE 9: REGULATION AND CARDIAC FUNCTION [PDF]
Abnormalities in cardiac stress signaling underlie a number of cardiovascular diseases (e.g. arrhythmias and heart failure). Cardiac stress signaling pathways normally integrate signals from the sympathetic nervous system to promote efficient contraction

Transcriptome analysis of mouse and human sinoatrial node cells reveals a conserved genetic program
The rate of contraction of the heart relies on proper development and function of the sinoatrial node, which consists of a small heterogeneous cell population, including Tbx3+ pacemaker cells. Here, we have isolated and characterized the Tbx3+ cells from

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 ...

Two Decades of Optogenetic Tools: A Retrospective and a Look Ahead
Optogenetics provides up to millisecond scale, cell type‐specific control of biology using light‐sensitive proteins. This review chronicles two decades of tool development, from microbial rhodopsins and photoactivated enzymes to allosteric switches, surveys broad applications in neuroscience, molecular and cell biology, cardiology, immunology, and ...

Heart rate (HR) and HR variability (HRV), predictors of over-all organism health, are widely believed to be driven by autonomic input to the sinoatrial node (SAN), with sympathetic input increasing HR and reducing HRV. However, variability in spontaneous

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

Effects of Cardiac Structural Remodelling During Heart Failure on Cardiac Excitation – Insights from a Heterogeneous 3D Model of the Rabbit Atria [PDF]
Heart failure is a leading cause of morbidity and mortality in the western world. One of the effects of heart failure is the structural remodelling of cardiac tissue, including tissue dilation and development of fibrosis.

Impact of functional studies on exome sequence variant interpretation in early-onset cardiac conduction system diseases [PDF]
Aims The genetic cause of cardiac conduction system disease (CCSD) has not been fully elucidated. Whole-exome sequencing (WES) can detect various genetic variants; however, the identification of pathogenic variants remains a challenge.

Computer Three-Dimensional Reconstruction of the Sinoatrial Node [PDF]
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).
