Cardiac skeleton

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Cardiac skeleton (sometimes called “fibrous skeleton of the heart”) refers to the structure of dense connective tissue in the heart that separates the atria from the ventricles.

It is not a “true” skeleton, but it does provide structure and support for the heart, as well as isolating the electric charges that go through the heart.
