This is the electrical conduction system of the heart.

They are also found in Purkinje fibersin the electrical conduction system of the heart.

He is best known for his research in the anatomy of the coronary arteries and the electrical conduction system of the heart.

Disorders affecting the cardiomyocytes that make up the electrical conduction system of the heart are called heart blocks.

It alters characteristics of the electrical conduction system of the heart, and so has the potential to affect the cardiac cycle.

"A test of the electrical conduction system of the heart (the system that generates the heart beat)."

In the electrical conduction system of the heart, calcium replaces sodium as the mineral that depolarizes the cell, proliferating the action potential.

A heart block can be a blockage at any level of the electrical conduction system of the heart (shown in the diagram on the right).

Progressive degeneration of the electrical conduction system of the heart can lead to third-degree heart block.

Binge drinking increases cardiovascular toxicity due to its adverse effects on the electrical conduction system of the heart and the process of atherothrombosis.

The 'cardiac action potential' is a specialized action potential in the heart, with unique properties necessary for function of the electrical conduction system of the heart.

Repair of most VSDs is complicated by the fact that the Electrical conduction system of the heart is in the immediate vicinity.

Such scarring can disrupt the electrical conduction system of the heart, and may also irritate surrounding viable ventricular myocytes making them more likely to depolarize spontaneously.

As noted above, the calcification process that occurs in aortic stenosis can progress to extend beyond the aortic valve and into the electrical conduction system of the heart.

While under anesthesia, patients with FOP may face problems, which include difficulties with intubation, restrictive pulmonary disease, and changes in the electrical conduction system of the heart.

Mahaim fibers are portions of the electrical conduction system of the heart which connect to the interventricular septum, though there is some disagreement about their exact insertion.

Lev's disease (or Lenegre-Lev syndrome) is an acquired complete heart block due to idiopathic fibrosis and calcification of the electrical conduction system of the heart.

An ectopic pacemaker can reside within a part of the electrical conduction system of the heart, or within the muscle cells of the atria or ventricles.

It indicates a failure of the electrical conduction system of the heart to stimulate the ventricles (which would lead to the absence of heartbeats, unless ventricular escape beats occur).

Main article: Electrical conduction system of the heart The heart's electrical activity begins in the sinoatrial node (the heart's natural pacemaker), which is situated on the upper right atrium.

This shortcut across the chamber of the ventricle seems to facilitate conduction time, allowing coordinated contraction of the anterior papillary muscle; (see electrical conduction system of the heart).

Tawara's branches - alternative name for the left and right bundle branches in the electrical conduction system of the heart (between the bundle of His and the Purkinje fibres)

Afterdepolarizations are abnormal depolarizations of cardiac myocytes that interrupt phase 2, phase 3, or phase 4 of the cardiac action potential in the electrical conduction system of the heart.

First-degree AV block, or PR prolongation, is a disease of the electrical conduction system of the heart in which the PR interval is lengthened beyond 0.20 seconds.

The normal electrical conduction system of the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to and stimulate the myocardium (muscle of the heart).
