The sophisticated architecture of the rat atrioventricular node
… spontaneously generated in the sinoatrial (SA) node propagates through the atria to reach the atrioventricular (AV) node. As the only conduction pathway between the atria and ventricles, the AV node functions to delay and regulate action potential conduction between the atria and ventricles. …

The electrophysiology of the atrioventricular node in normal and failing rabbit hearts
… heart failure (CHF). Previous investigators have observed abnormal delay in atrioventricular (AV) conduction in a rabbit model of left ventricular dysfunction (LVD) due to apical myocardial infarction. In this model, AV conduction time increased with increasing pacing rates, suggesting the …

Radiofrequency ablation versus cryoablation in the treatment of atrioventricular nodal reentrant tachycardia
Atrioventricular nodal reentrant tachycardia (AVNRT) is an abnormal heart rhythm caused by aberrant electrical conduction within the AV node. AVNRT is the most common type of paroxysmal supraventricular tachycardia (PSVT), with approximately 50,000 new cases per year in the United States. Catheter …

Chronische Modulation des parasympathischen Nerventonus des Atrioventrikularknotens : Entwicklung eines Neurostimulators mit transvenöser Sondenimplantation zur ventrikulären Frequenzkontrolle bei Vorhofflimmern
… as hypotension or bradycardia. Previous studys have shown, that the inferior interatrial ganglionated plexus (IAGP) selectively innervates the AV node. Temporary electrical stimulation of this plexus elicits a reduction of ventricular heart rate in patients with atrial fibrillation.METHODS: In 10 …

A study of phase resetting, mutual entrainment, and modified ventricular parasystole using a model of coupled heart cells
… previous studies of cell interaction which have used simplified models of a general cardiac cell or oscillators characterized only by their phase transition curves the present work incorporates the more physiologically realistic cell models of the Hodgkin-Huxley type. Furthermore, this …

Herzschlaglängenfolgen während Taktatmung als Marker der kardiorespiratorischen Innervation
… between circle maps. We supposed patients after AV-node-modification (AVNM) to present a lower autonomic innervation level in 24h-holter-monitoring and Kullback information gain. 18 young (25 ± 4 years, 10m, 8f) and 14 old (58 ± 10 years, 7m, 7f) healthy probands underwent 24h-holter-monitoring …

Autonome Modulation von Sinusknoten, AV-Knoten und ventrikulärer Repolarisation von Patienten mit Herzinsuffizienz im Vergleich zu Gesunden
… autonome Modulation von Sinusknoten und AV-Knoten bestehen kann. Ziel dieser Arbeit war es, die autonome Modulation von Sinusknoten, AV-Knoten und ventrikulärer Repolarisation bei älteren Probanden und bei Herzinsuffizienten zu untersuchen. In dieser Arbeit wurde zunächst auch bei älteren …
