Demonstration of entrance block into the atrioventricular node of man.
نویسندگان
چکیده
was demonstrated in five patients by using programmed atrial stimulation and His bundle recordings. Entrance block into the A-V node occurred in a narrow range (28-33%) of the basic cycle length and concealed conduction occurred at coupling intervals longer than this range. It appears that entrance block of these early APBs is due to a "functional block" between the atrium and the A-V node. The concept of an entrance block into the A-V node is useful in explaining some forms of the supernormal phase of A-V conduction as well as in the interpretation of complex arrhythmias.

Introduction: Recent studies have shown acute cardioprotective effects of cyclosporine. The aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using extracellular field potential recordings of isolated atrioventricular-node (AV-node) of rabbit. Methods: This study was performed on isolated double-per...

Background: Cardiac conduction disorders are rare syndromes in neonates and children. According to the literature atrial septal defect, especially ostium secundum type, is associated with atrioventricular (AV) block. Wenckebach conduction heart block is very rare in a neonate; however, there is a dearth of research on the prevalence of this type of heart block regarding the neonates and pediatr...

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...

Introduction: Ouabaine is a well-known atrioventricular (AV) node depressant agent, but its effects on functional properties of the AV node have not been cleared. The aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the AV node. Methods: Selective stimulation protocols were used to quantify independently electrophysiological prop...
