Histological study of the atrioventricular node and bundle in the heart of ovine fetus
This study was conducted on the atrioventricular node (AVN) and atrioventricular bundle (AVB) of fivefour-month-old ovine fetuses. The histological structure of these components was studied by routinehistological techniques and use of specific staining methods. The AVN was caudally located adjacent to theroot of the aorta. It was almost spherical in shape and consisted of twisty cells. The node...
متن کاملComputer three-dimensional reconstruction of the atrioventricular node.
Because of its complexity, the atrioventricular node (AVN), remains 1 of the least understood regions of the heart. The aim of the study was to construct a detailed anatomic model of the AVN and relate it to AVN function. The electric activity of a rabbit AVN preparation was imaged using voltage-dependent dye. The preparation was then fixed and sectioned. Sixty-five sections at 60- to 340-micro...
متن کاملThe role of Na+-K+-ATPase in the basic and rate-dependent properties of isolated perfused rabbit Atrioventricular Node
Introduction: Ouabaine is a well-known atrioventricular (AV) node depressant agent, but its effects on functional properties of the AV node have not been cleared. The aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the AV node. Methods: Selective stimulation protocols were used to quantify independently electrophysiological prop...
متن کاملMesothelioma of the atrioventricular node.
A patient with Mobitz type 2 heart block caused by a mesothelioma of the atrioventricular node died of a subarachnoid haemorrhage at the age of 33 two years after implantation of a permanent pacemaker. Mesothelioma of the atrioventricular node is rare, and reported cases have all been diagnosed post mortem. Mesothelioma of the atrioventricular node should be considered in the differential diagn...
متن کاملA Sluggish Atrioventricular Node
A 37 year old male with a history of peptic ulcer disease presented to the emergency room with nausea and vomiting. He reported two recent episodes of syncope, but denied other associated symptoms including palpitations, hematemesis, melena, chest pain, or dyspnea. He reported recent use of marijuana, but denied use of cocaine or methamphetamines. The patient reported similar symptoms in 2006 w...
