Significats de av node en anglès

The heat-sensitive area is located over, or very close to, the compact AV node.

Animals were studied with intact AV node or following ablation to achieve ventricular rate control.

AV blocks that could be related to fibrosis of the AV node were also observed.

In light-microscopical studies with peroxidase-conjugated secondary antibodies, heavy immunostaining was seen in SA and AV nodes.

Histology showed that the heat-sensitive area was located over, or close to, the compact AV node.

Ablation of the AV node is effective with a double freeze-thaw cycle using a percutaneous catheter cryoablation system.

Following a total AV node ablation, patients were randomized to DDDR versus VDD pacing and followed for 1 year.

K2P2.1 expression in the left atrium, AV node, and ventricles was not affected by AF.

Conclusion: Our results indicate that autonomic control of the sinus and AV nodes is preserved following successful radiofrequency ablation of AVNRT.

The effects of posteroseptal radiofrequency current application are not necessarily mediated by changes in the autonomic input to the AV node.

We investigated whether successful ablation of AVNRT is associated with an alteration of autonomic input to the sinus and AV nodes.

Intraoperative electrophysiologic study localized the atrial insertion of type 1 pathways to the midpoint of Koch's triangle close to the AV node.

The observation suggests that the slow pathway in this patient found its anatomic substrate in the inferior extension of the compact AV node.

The objective of this study was to reconstruct the human compact AV node in relation to the landmarks of Koch's triangle, with emphas …

This is the first documentation of RF ablation interrupting an inferior extension of the compact AV node in a patient successfully ablated for AVNRT.
