A model of the cardiac conduction system is considered. The model provides an insight into the electrical processes in the myocardium under normal and pathological conditions. The model takes into account the involvement of the atria in generating the sinus rhythm of the heart and the sinus rhythm...
In order to clarify the importance of the conduction system involvement in cases of sudden cardiac death, 35 autopsied hearts, obtained from the patients who died within one hour after the onset of a critical attack, were examined histopathologically and compared with 27 both age- and disease-...
Recently, several techniques have been developed in order to record non-invasively specialized conduction system (SCS) potentials in human. The current study was undertaken to assess a new type of high resolution electrocardiography (HRC) using the averaged signal of 128 successive cardiac beats (AC...
Cardiac arrhythmias and conduction disturbances are accompanied by structural remodelling of the specialised cardiomyocytes known collectively as the cardiac conduction system. Here, using contrast enhanced micro-computed tomography, we present, in attitudinally appropriate fashion, the first 3-dimensional repre...
(AV) node activity, and impose a time-of–day dependent susceptibility to ventricular arrhythmia. Critically, the balance of circadian inputs from the autonomic nervous system and cardiomyocyte clock to the SA and AV nodes differ, and this renders the cardiac conduction system sensitive to ...

Scars can create conduction blocks and have therefore been described as electrical insulators [[34], [35], [36]]. But is a fibrotic scar really non-conductive? Catheter ablation is a clinical intervention by which a tightly focused lesion is induced by a local energy delivery in order to ...
The aim of this paper is to introduce a new mathematical model that simulates myocardial blood perfusion that accounts for multiscale and multiphysics features. Our model incorporates cardiac electrophysiology, active and passive mechanics, hemodynamics,
spike-ins were added to the lysis buffer to obtain 1:20,000 dilutions of the final cDNA samples. Cells in IFCs were processed using the Fluidigm C1™ Single-Cell Auto Prep System. After single cells were primed into compartments, cell numbers (single or multiple cells) and the quality (...
