|The sinoatrial node (SA node or SAN) is the impulse generating (pacemaker) tissue located in the right atrium of the heart, and determines the heart rate. It is a group of cells positioned on the wall of the right atrium, near the entrance of the superior vena cava and measures about 10mm x 3mm.|
|3 internodal tracts which extend from the SA node to the AV node. 1.Anterior inter nodal tract of Bachman 2.Middle inter nodal tract of Wenckebach 3.Posterior inter nodal tract of Thorel|
