Concealed conduction of premature ventricular complexes resulting in AV nodal block

.

Nodal recovery, dual pathway physiology, and concealed conduction determine complex AV dynamics in human atrial tachyarrhythmias.

The genesis of complex ventricular rhythms during atrial tachyarrhythmias in humans is not fully understood. To clarify the dynamics of atrioventricular (AV) conduction in response to a regular high-rate atrial activation, 29 episodes of spontaneous or pacing-induced atrial flutter (AFL), covering a wide range of atrial rates (cycle lengths from 145 to 270 ms), were analyzed in 10 patients. AV ...

Ventricular Response in Atrial Fibrillation. Role of Concealed Conduction in the Av Junction.

CONCEALED CONDUCTION in the atrioventricular (AV) junction in association with coordinated atrial activity is a well-recognized phenomenon,1-3 recently confirmed with new technics in animal experiments.4-6 Its operation in atrial fibrillation has received less attention, although it appears to offer the best explanation for the characteristic irregularity of the ventricular responses.7 11 It is...
