Longitudinal dissociation within the posterior AV nodal input of the rabbit: a substrate for AV nodal reentry.
BACKGROUND Longitudinal dissociation of an anatomic pathway into 2 electrophysiologically distinct pathways has been hypothesized as a basis for localized AV nodal reentry and supraventricular arrhythmias. METHODS AND RESULTS Extracellular bipolar and intracellular microelectrodes were used to record activation in the superfused rabbit AV junction. A subset of rabbit hearts (n=19 of 72) demon...
متن کاملAnalogy of electronic pacemaker and ventricular parasystole with observations on refractory period, supernormal phase, and synchronization.
THE INTRODUCTION of electronic (artificial) pacemakers in the management of patients with transient and permanent coin-plete heart block has met with outstanding success. Miniaturization has in turn given rise to small portable units and to smaller implantable onles. With the latter, the stimulus is standardized and in most types the rate (cycle) is preset and nonadjustable. As yet, there seems...
متن کاملInterference dissociation in the presence of dual atrioventricular nodal physiology
Introduction Dual atrioventricular nodal physiology (DAVNP) is present in 10% to 35% of the general population and is known to regress with aging. It usually manifests as a critical AH jump on electrophysiologic testing or on surface electrocardiography as a change in PR interval with subsequent tachycardia. Preferential choice of pathway engagement (slow vs fast) is dependent upon refractory p...
متن کاملAtrioventricular ring reentry in embryonic mouse hearts.
BACKGROUND During development, AV conduction switches from base-to-apex to apex-to-base conduction after emergence of the conduction system. We hypothesize that after this transition, the bulk of the AV ring, although no longer required for AV conduction, remains transiently able to conduct, providing a potential arrhythmia substrate. We studied AV conduction during this transition and its sens...
متن کاملDiagnostic dilemma with a narrow QRS regular rhythm at normal rates in a patient with corrected transposition of great arteries.
A 35 year old male, known case of corrected transposition of great arteries presented with exertional dyspnea and recurrent pre-syncope. 12 lead electrocardiogram revealed a regular rhythm at 75 beats per minute, P waves occurring on the upstroke of T waves and apparent 1:1 P-QRS relationship. The possibilities to be considered - complete AV block with junctional escape, junctional rhythm with ...
