Connexin diversity in the heart: insights from transgenic mouse models
Cardiac conduction is mediated by gap junction channels that are formed by connexin (Cx) protein subunits. The connexin family of proteins consists of 24 members, varying in their biophysical properties and ability to combine with other connexins into ...

Anatomic-electrophysiological correlations concerning the pathways for atrioventricular conduction. [PDF]
The remarkable success of radiofrequency ablation in recent decades in curing atrioventricular nodal reentrant tachycardias has intensified efforts to provide a solid theoretical basis for understanding the mechanisms of atrioventricular transmission ...

Newly identified NO-sensor guanylyl cyclase/connexin 43 association is involved in cardiac electrical function [PDF]
Background: Guanylyl cyclase, a heme-containing alpha 1 beta 1 heterodimer (GC1), produces cGMP in response to Nitric oxide (NO) stimulation. The NO-GC1-cGMP pathway negatively regulates cardiomyocyte contractility and protects against cardiac ...

Emerging from the Darkness. Sudden Cardiac Death in Cardiac Amyloidosis
Cardiac amyloidosis (CA) manifests as infiltrative cardiomyopathy with a hypertrophic pattern, usually presenting with heart failure with a preserved ejection fraction. In addition, degenerative valvular heart disease, particularly severe aortic stenosis,

Numerical simulation of electrocardiograms for full cardiac cycles in healthy and pathological conditions [PDF]
This work is dedicated to the simulation of full cycles of the electrical activity of the heart and the corresponding body surface potential. The model is based on a realistic torso and heart anatomy, including ventricles and atria.

Erbb2 is required for cardiac atrial electrical activity during development.
The heart is the first organ required to function during embryonic development and is absolutely necessary for embryo survival. Cardiac activity is dependent on both the sinoatrial node (SAN), which is the pacemaker of heart's electrical activity, and ...

Syncytium calcium signaling and macrophage function in the heart
Macrophages are traditionally viewed as a key component of the immunity defense system. Recent studies have identified resident macrophages in multiple organs including the heart, in which the cells perform their crucial role on tissue repair after ...
