Aberrant ventricular conduction and ventricular ectopy.

Aberrant ventricular conduction and ventricular ectopy.

Differentiation between aberrant ventricular conduction and ventricular ectopy in atrial fibrillation using RR interval scattergram.

BACKGROUND Differentiation between aberrant ventricular conduction and ventricular ectopy during atrial fibrillation (AF) is of etiologic, prognostic, and therapeutic importance. We developed a noninvasive technique to diagnose aberrant ventricular conduction and ventricular ectopy in AF. METHODS AND RESULTS We studied the Holter ECGs of 34 patients with paroxysmal AF and 62 patients with chr...

Aberrant 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,...
