The sinoatrial node receives action potentials from the Atrioventricular (AV) node.

The sinoatrial node (SA node) is the normal pacemaker for the heart. The SA node is located in the upper right atrium and close to the superior vena cava. Pacemaker sources other than the SA Node can be said to be abnormal pacemakers or one of the characteristics of cardiac arrhythmias/dysrhythmias on the EKG image. To carry out its function as a normal pacemaker for the heart, the SA Node is influenced by the autonomic nervous system, namely sympathetic and parasympathetic activity. There is an increase in the work of the SA Node (increased heart rate) and conversely, the presence of parasympathetic activity will decrease the work of the SA Node (decreased heart rate)

The AV Node is the second source of pacemakers after the SA Node. The size of the AV node is smaller than the SA node, located in the lower right atrium, to be precise, close to the tricuspid valve and also close to the coronary sinus ostium.
