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...
The cardiac conduction system is designed with some very specific considerations as to the speed of conduction from the SA node to the apex of the heart. Knowing the conduction delay between the various segments within the cardiac conduction system, estimate the conduction speed through each portion...
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...
Within the most upregulated response pathways, we also explored signaling responses previously implicated in the modulation of cardiac conduction. The Notch signaling pathway, which plays an important role in conduction system development31,32,33, was present at both timepoints (Fig. 5a). Furthermore...

The heart has specialized conduction pathways in both the atria and the ventricles that enable the rapid conduction of excitation impulses (i.e. depolarizations) from the SA node throughout the myocardium. These specialized conduction pathways conduct the depolarizations from the SA node to the atri...
conduction system, complex geometric structures, and heterogeneouscellular electrophysiologyin diseased and healthy rabbit hearts to the initiation and maintenance ofventricular arrhythmia. Finally, it will provide an overview on the contributions of rabbit ventricular modeling on understanding the mechanisms ...
In the heart, the ventricular conduction system propagates the electrical impulses that coordinate ventricular chamber contraction. The QRS interval on an electrocardiogram (ECG) is used clinically to quantify duration of ventricular depolarization in the heart. Prolonged QRS duration is an independent pre...
The Bundle of His passes the electrical impulse to the infranodal conduction system through the cardiac skeleton. The fibrous skeleton of the heart is a supportive and functional structure formed by fibrous rings of high-density connective tissue (annulus fibrosus) surrounding the two atrioventricular ...
