  • nodal
  • Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (lexic.us)
  • Cells located in the AV node sit at a relatively higher resting membrane potential than surrounding atrial and ventricular myocytes, exhibit spontaneous depolarization during phase 4 of the action potential, and have slower phase 0 depolarization (mediated by calcium influx in nodal tissue) than that seen in ventricular tissue (mediated by sodium influx).

  • Interestingly, the AV node-specific gene repertoire consisted of multiple neurotrophic factors not yet appreciated to play a role in nodal development. (omicsdi.org)
  • We used a novel AV nodal myocardium-specific reporter mouse to gain insight into the gene programs determining the formation and phenotype of the developing AV node. (omicsdi.org)
  • In a randomized, observer-blind study, the effect of incremental doses of pindolol 0.001, 0.002, 0.003, and 0.004 mg/kg IV and propranolol 0.01, 0.02, 0.03, and 0.04 mg/kg IV on SA nodal recovery time (SNRT) and atrioventricular conduction interval (AH) was assessed in 20 patients (15 men and 5 women age range thirty to seventy-two, mean age fifty-three).

  • AVNRT
  • [ 3 ] Nakagawa and Jackman have described multiple atypical AVNRT circuits using rightward and leftward inferior extensions of the AV node. (medscape.com)
  • compact AV node
  • The slow pathway(s) approach the compact AV node from inferiorly and have a relatively longer conduction time and an ERP that typically is short when compared to fast pathway ERP. (medscape.com)
  • coronary
  • The pigs were placed under general anesthesia, and coronary/cardiac computed tomography simulation scans were performed to localize the AV node. (ahajournals.org)
  • transcription
  • These data present the first genome-wide transcription profiles of the AV node during development, providing valuable information concerning its molecular identity. (omicsdi.org)
