Aberrant Ventricular Conduction Types and Concealed Conduction
Aberrant ventricular conduction definition: It is a term applied to alterations in QRS contour of supraventricular beats resulting from impulse transmition during periods of physiologic refractoriness and/or depressed conductivity. The supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused wi...
متن کاملExperimental production of aberrant ventricular conduction in man.
SUMMARY Aberrant ventricular conduction (AbC) was produced in 17 of 18 subjects, including six normal persons, by the introduction of electric stimuli via a transvenous catheter situated in the right atrium. Analysis of electrophysiological determinants indicated that AbC was favored by a long cycle preceding the short cycle which terminated in the aberrant complex, a short R to stimulus coupli...
متن کاملAberrant Ventricular Conduction
Escape beats recorded in clinical electrocardiograms sometimes differ in contour and QRS duration from conducted beats, and this in spite of their having a relatively short cycle length. This suggests a location of the subsidiary pacemaker above the bifurcation of the common A-V bundle. While this, unlike other types of aberrant ventricular conduction, cannot be explained on a functional basis,...
