Medical - Medical: Cardiology
English term or phrase: sinus node
Definition from Medical University of South Carolina:
bundle of excitatory tissue found in the right atrium that functions as the pacemaker of the heart

Example sentence(s):
  • The autonomic nervous system, the same part of the nervous system as controls the blood pressure, controls the firing of the sinus node to trigger the start of the cardiac cycle. medterms.com
  • If the sinus node is not functioning normally -- due to damage from surgery, drugs, congenital heart defects or other causes -- the heartbeat may become very slow with a decrease in blood pressure. University of California
  • Extrinsic sinus mechanisms of sinus node dysfunction could be drug effects or due to autonomic influences. The important drugs which could suppress sinus node function are beta blockers, non-dihydropyridine calcium channel blockers (e.g. verapamil and diltiazem), digoxin, clonidine, methyl dopa, class IA, IC and III antiarrhythmic agents and lithium.

node sinusal


Definition from Diccionari Enciclopèdic de Medicina:
El node de Keith i Flack és un node de teixit especialitzat cardíac on s'originen els impulsos elèctrics del cor, situat a la regió del solc terminal. Proporciona tres fascicles, anomenats internodals, que el comuniquen amb el node d'Aschoff i Tawara: el fascicle posterior o de Thorel, el mitjà o de Wenckebach i l'anterior, proveït d'una branca (fascicle de Bachmann) que de l'aurícula dreta va a l'aurícula esquerra. Consta de cèl·lules P (on s'origina l'impuls elèctric cardíac), cèl·lules de transició (que el transmeten) i cèl·lules o fibres de Purkinje (que el propaguen). També és anomenat node sinusal o sinoauricular, aparell atriovector (o simplement atriovector).

Example sentence(s):
  • Així, el nostre cor disposa d’un marcapassos natural anomenat node sinusal que emet un senyal elèctric que es distribueix a través d’un sistema de conducció (circuit elèctric) que utilitza aquesta energia per generar la contracció del múscul cardíac. - CardioClinic Sant Cugat
