Source sentences:
text: The heart rate is established by the Sinoatrial Node (SAN) - the pacemaker of the cardiac muscle.
text: it begins with an action potential in the sinoatrial node (SA) transmitted through the conducting system and produces an action potential in the cardiac muscle cells (contractile cells).
text: These pacemakers are known as SA (sinoatrial node) and AV (atrioventricular node).
text: In healthy hearts, these cells are found in the right atrium and are called the sinoatrial node (SAN; see below for more details).
text: The electrical signal travels from the sinoatrial node (SAN), which stimulates the atria to contract, to the atrioventricular node (AVN) which slows down conduction of the action potential, from the atria to the ventricles.
text: At the entrance of the right atrium, sinus node (sinoatrial node [SAN]) myocytes generate the impulse to activate the atrial myocardium.
