sinoatrial node (SA)
|
pacemaker, begins heartbate at right atrium

atrioventricular (AV) node
|
located at the base of the right atrium proximal to the interatrial septum
|
|
|

|
signal travels from AV node to this bundle in the interatrial septum, transmit the impulse to the Purkinje fibers in the right and left ventricles

|
heart pain - Atypical pain is a stabbing or burning pain that is variable in location and intensity, unrelated to exertion.
