Primary oxalosis with pan-conduction cardiac disease: electrophysiologic and anatomic correlation.
A 27-year-old man with primary oxalosis and extensive visceral involvement was maintained on long-term chronic hemodialysis. He had an episode of presyncope associated with electrocardiographic findings of an erratic atrial rhythm, atrioventricular dissociation due to an accelerated junctional rhythm and right bundle branch block. Electrophysiologic studies showed irregular atrial depolarizatio...
متن کاملCardioembolic stroke in primary oxalosis with cardiac involvement.
Primary oxalosis is a rare disorder of oxalate metabolism, characterized by nephrocalcinosis, nephrolithiasis, and extrarenal deposition of calcium oxalate in several tissues, including the heart. We report the case of a 34-year-old man with sudden right hemiparesis and aphasia from the occlusion of the left middle cerebral artery. Clinical features and the results of laboratory investigations ...
متن کاملCardiac Conduction System: Delineation of Anatomic Landmarks With Multidetector CT
Major components of the cardiac conduction system including the sinoatrial node (SAN), atrioventricular node (AVN), the His Bundle, and the right and left bundle branches are too small to be directly visualized by multidetector CT (MDCT) given the limited spatial resolution of current scanners. However, the related anatomic landmarks and variants of this system a well as the areas with special ...
متن کاملElectrical conduction in canine pulmonary veins: electrophysiological and anatomic correlation.
BACKGROUND Paroxysmal atrial fibrillation in patients is often initiated by foci in the pulmonary veins. The mechanism of these initiating arrhythmias is unknown. The aim of this study was to determine electrophysiological characteristics of canine pulmonary veins that may predispose to initiating arrhythmias. METHODS AND RESULTS Extracellular recordings were obtained from the luminal side of...
متن کاملAnisotropic conduction in the triangle of Koch of mammalian hearts: electrophysiologic and anatomic correlations.
OBJECTIVES The purpose of this study was to characterize anisotropy in the triangle of Koch by relating electrophysiology with anatomy. BACKGROUND Atrioventricular (AV) node fast and slow pathway characteristics have been suggested to be due to nonuniform anisotropy in the triangle of Koch. METHODS During atrial pacing, we determined the electrical activity within the triangle of Koch by mu...
