Descriptor nodo sinoatrial
Entry term(s) nodo SA
nodo sinoauricular
nódulo de Keith-Flack
nódulo sinoatrial
nódulo sinusal
Scope note: Pequeña masa de fibras musculares cardíacas modificadas que se localiza en el punto de unión de la VENA CAVA SUPERIOR con el atrio derecho. Probablemente los impulsos contráctiles se inician en este nódulo, se propagan por los atrios (ATRIO CARDÍACO) y posteriormente se transmiten, mediante el haz de His (HAZ ATRIOVENTRICULAR), hacia los ventrículos (VENTRÍCULO CARDÍACO).

RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D012849
Scope note: The small mass of modified cardiac muscle fibers located at the junction of the superior vena cava (VENA CAVA, SUPERIOR) and right atrium. Contraction impulses probably start in this node, spread over the atrium (HEART ATRIUM) and are then transmitted by the atrioventricular bundle (BUNDLE OF HIS) to the ventricle (HEART VENTRICLE).
