Histological study of the atrioventricular node and bundle in the heart of ovine fetus
This study was conducted on the atrioventricular node (AVN) and atrioventricular bundle (AVB) of fivefour-month-old ovine fetuses. The histological structure of these components was studied by routinehistological techniques and use of specific staining methods. The AVN was caudally located adjacent to theroot of the aorta. It was almost spherical in shape and consisted of twisty cells. The node...

متن کاملSpread of activity through the atrioventricular node.
TRAXSMEMBRANE recording from single fibers of the atrioventricular (A-V) node of the rabbit heart has shown action potentials exhibiting rising phases with a much slower time course than those of plain heart muscle.' It has also been shown that the area in which such nodal potentials are recorded is not sharply delimited, regions being found at each side of the nodal area in which action potent...
متن کاملCryosurgical treatment of atrioventricular node
Paroxysmal supraventricular tachycardia most commonly arises from reentry within the atrioventricular (AV) node. Although ablation of the His bundle has gained popularity for treating patients with AV node reentrant tachycardia refractory to medical therapy, undesirable sequelae include complete heart block and the necessity for a permanent pacemaker. To obviate this limitation, we have develop...
