The approach to supraventricular tachycardia (SVT) diagnosis can be complex because it involves synthesizing baseline electrophysiologic features, features of the SVT, and the response(s) to pacing maneuvers. In this two-part review, we will mainly explore the latter while recognizing that neither of the former can be ignored, for they provide the context in which diagnostic pacing maneuvers mu...
Autoantibodies are infrequently detected in the sera of patients with the demyelinating form of Guillain-Barré syndrome most commonly encountered in the Western world, despite abundant circumstantial evidence suggesting their existence. We hypothesised that antibody specificities reliant on the cis interactions of neighbouring membrane glycolipids could explain this discrepancy, and would not h...
introduction: the aim of the present study was to determine direct effects of no modulation on protective electrophysiological properties of atrioventricular node (av node) in the experimental model of af in rabbit. methods: isolated perfused rabbit av nodal preparations were used in two groups. in the first group (n=7), lname (50μm) was applied. in the second group (n=12), different concentrat...
introduction: developmental changes in atrioventricular nodal conduction time and refractoriness have been shown in several studies. prevalence of atrioventricular nodal reentrant tachycardia (avnrt) is clearly age-dependent. the purpose of this study was to determine developmental changes of basic and frequency-dependent electrophysiological properties of the atrioventricular node (av-node) in...
Cardiac arrhythmias are among the leading causes of mortality. They often arise from alterations in electrophysiological properties cardiac cells and their underlying ionic mechanisms. It is therefore critical to further unravel pathophysiology basis human electrophysiology health disease. In first part this review, current knowledge on differences ion channel expression processes that determin...
Hyperkalemia is a common clinical condition among heart failure patients especially if there coexisting older age, potassium-sparing medication, and renal insufficiency. Close follow-up titration of renin-angiotensin-aldosterone system inhibitors are essential to prevent the development hyperkalemia. It can also cause significant abnormalities in with cardiac implantable electronic devices (CIE...
