Electrophysiologic studies have documented block distal to the atrioventricularnode in these patients.
2
Rhythm disturbances are common and include sinus node dysfunction, superconductor atrioventricularnode or heart block.
3
N-acetylprocainamide increased the functional refractory period of the atrioventricularnode, but to a lesser extent than procainamide.
4
Autopsy revealed a giant rheumatoid nodule located on the mitral valve and extending to the atrioventricularnode.
5
A recent anatomic study has revived interest in the inferior extensions of the compact atrioventricularnode in humans.
1
The heat-sensitive area is located over, or very close to, the compact AVnode.
2
Animals were studied with intact AVnode or following ablation to achieve ventricular rate control.
3
AV blocks that could be related to fibrosis of the AVnode were also observed.
4
In light-microscopical studies with peroxidase-conjugated secondary antibodies, heavy immunostaining was seen in SA and AVnodes.
5
Histology showed that the heat-sensitive area was located over, or close to, the compact AVnode.
Uso de a-v node em inglês
1
The ERP of the A-Vnode (seven cases) was prolonged in found and the FRP was increased in three.
2
In addition, the sinu-atrial conduction time, the conduction velocity within the right atrium, the A-Vnode and the His-Purkinje system can be measured.
3
Procainamide is known to depress conduction through the A-Vnode, and this property may facilitate the development of ventricular reciprocal beats or echoes.
