Retrograde concealed conduction in the atrioventricular node: differential manifestations related to level of intranodal penetration.

Although concealed conduction in the atrioventricular node (AVN) has been the focus of numerous experimental and clinical studies, little is known about the differential effects on AVN functional behavior of prior concealed retrograde impulse penetration alone vs prior anterograde or dual AVN activation. This study was undertaken specifically to investigate this aspect of human AVN physiology i...

Concealed retrograde conduction in complete atrioventricular block.

INCOMPLETE TRANSMISSION of impulses across the atrioventricular (A-V) junction has held a special fascination for many investigators.'14 Varied investigational techniques including venous pulse waves, standard electrocardiograms, and direct catheter electrode recordings from the cardiac chambers have been used to further the understanding of retrograde transmission of impulses into the A-V junc...

Concealed and supernormal atrioventricular conduction.

THE FAILURE of a cardiac impulse to traverse the entire atrioventricular (AV) conducting system is called concealed conduction. Electrocardiographically, the effects of concealed conduction are reflected in the conduction and/or formation of subsequent beats.1 The concept of concealed conduction can be applied to explain (1) post-extrasystolic prolongation of the P-R interval, (2) the irregular...
