What Is Cardiac Action Potential? What is Electrical Stimulation? What is the Sinus Node? What Is an Atrial Natriuretic Factor? What is Cardiac Rhythm Management? What is a Recovery Heart Rate? Discussion Comments WiseGeek, in your inbox
Abnormalities of ventricular action potential cause malignant cardiac arrhythmias and sudden cardiac death. Here, we aim to identify microRNAs that regulate the human cardiac action potential and ask whether their manipulation allows for therapeutic modu
We model electrophysiology by the evolution of the transmembrane potentialvin the left ventricle via themonodomain equation49. We denote the electrophysiology problem in compact form as $$\begin{aligned} {\mathscr {E}} (v; \varvec{w}, \varvec{z}, \varvec{d}^{\textrm{s}}) = 0 \; \...

Within the SA node, action potential propagation is unusually slow owing to the expression of a low conductance gap junction, Cx45, at the expense of Cx43, which is prevalent throughout the chamber myocardium6. The pacemaker cells are uniquely shaped, with elongated morphology and disorganized ...
B The graph displays the mean cellular compositions of cardiomyocytes, fibroblasts, and endothelial cells across 11 different batches of COs and HOs. C Representative z-stack image of HOs and COs using confocal microscopy (left). Staining for cTnT (green) and VE-cad (red) in 2D monolayer ...
graph580shows a decreasing change in intracardiac impedance during cardiac cycles. The decreasing change would be manifested in several of the mentioned intracardiac impedance parameters. For example, the change in Zmaxbetween cardiac cycles would be decreasing, the slope of the intracardiac impedance wav...
