Preexcitation Syndromes - Heart Rhythm Center
due to delay of the premature impulse with the atrioventricular node (A-VN) (type I gap) or within the proximal HPS (type II gap). Gap phenomena are not ...
Wolff-Parkinson-White syndrome: Diagnostic and management ...In first-degree AV block, the electrical impulse is delayed on its journey from the sinus node to the ventricles. It is not, there- fore, a block at all but ... ECG differential diagnosis of narrow QRS complex tachycardia in ...Disorders in the AV node result in abnormal impulse pro- pagation and/or impulse formation. These are responsible for the generation of a set of arrhythmias ... Chapter 1: Electrophysiological patterning of the heartthis could occur only in LCP tissue, since the course of impulses taken within the AV node is otherwise the same during pacing and tachycardia.
