SINUS NODE Figure 3-9 SINUS NODE Top: The node (outlined) can be readily identified histologically by the abundant collagen and the sinus nodal artery running through the middle of it (black asterisk). Bottom: Nodal myocytes are accompanied by abundant collagen. (Both: Masson trichrome.) More about this image found in SINUS NODE Top: The node (outlined) can be readily identified histological...

CARDIAC SARCOIDOSIS: CONDUCTION SYSTEM INVOLVEMENT Figure 22-26 CARDIAC SARCOIDOSIS: CONDUCTION SYSTEM INVOLVEMENT Cardiac sarcoidosis frequently has a predilection for the cardiac conduction system. The associated fibrosis is seen here in the region of the sinoatrial (SA) node. The SA nodal More about this image found in CARDIAC SARCOIDOSIS: CONDUCTION SYSTEM INVOLVEMENT Cardiac sarcoidosis fre...

ATRIOVENTRICULAR (AV) NODE Figure 3-10 ATRIOVENTRICULAR (AV) NODE Top: The node (outlined) lies along the central fibrous body (right fibrous trigone) in the AV septum. Several small vessels are within the AV node. Bottom: Nodal myocytes are intertwined and show cross-striations.
