Experimental demonstration of concealed AV conduction in the human heart.
as an accepted method of treatment of StokesAdams disease, it became feasible to produce in the human heart conditions prone to reveal the phenomenon of concealed conduction. Simple experimental procedures can be applied at the bedside without danger or discomfort to the patient and various disturbances of cardiac rhythm can be reproduced at will. Such observations, some of which shed new light...
متن کاملElectrophysiological demonstration of concealed conduction in the human atrium.
In the course of electrophysiological evaluation of six patients with sick sinus syndrome, two patients with chronic conduction system disease and four patients with paroxysmal supraventricular tachycardia or atrial flutter-fibrillation, the phenomenon of concealed conduction within the atrium (At) was repeatedly observed. One pair of intracardiac electrodes was used to deliver electrical stimu...
متن کاملNodal 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 ...

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...
