ATRIOVENTRICULAR BLOCK
Cardiac fibrosis, responsible for an atrioventricular block. Inert fibrous tissues appear in the cardiac wall ; they are true isulators, that prevent the conduction of cardiac inflow. This fibrosis is primarily due to a decrease or verily a blockage of the electrical conduction between the atria and the ventricles ; the transmission of inflow is no longer made, or badly, between the sinus node (at the top of the right atrium, in yellow) and the atrioventricular node (between the right atrium and the right ventricle). It is the atrioventricular block. The fibrosis is responsible for 50 % of cases of atrioventricular blocks. This image is part of a series concerning anatomy, pathologies and cardiac treatments.
