cardiac skeleton

The cardiac skeleton establishes electrically impermeable boundaries to autonomic influence within the heart.

In normal anatomy the AV node is the only electrical conduit from the atria to the ventricles through the cardiac skeleton.

Given no aberrant channels, the atrial and ventricular Purkinje fibers are distinctly shielded from each other by collagen or the cardiac skeleton.

It also associated with hypertensive heart disease, aortic valvular disease, cardiomyopathies, and degenerative fibrotic disease of the cardiac skeleton.

The cardiac skeleton consists of four dense bands of dense connective tissue that encircle the bases of the pulmonary trunk, aorta, and heart valves.

The four collagenous valve rings, the central body of the heart and the extended cardiac skeleton of the heart are histologically and uniquely bound to cardiac muscle.

The cardiac skeleton, sometimes called the fibrous skeleton of the heart, is the structure of dense connective tissue in the heart that separates the atria from the ventricles.
