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...
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...
Cell-Type-Specific Electrophysiology In article number 2103564, Namsun Chou, Il-Joo Cho, and co-workers develop a multimodal multi-shank fluorescence neural probe system. The enables combined electro-optical recordings for cell-type-specific electrophysiology from multiple deep-brain regions at high spatiotemporal resolution. system gives new experimental paradigm to enable the precise investig...
هدف: این مطالعه به منظور بررسی میزان فراوانی بیماری lebers congenital amaurosis در تست های الکتروفیزیولوژیک در کودکان در پلی کلینیک قدس سال 90-89 انجام شده است. روش مطالعه: در این مطالعه مقطعی، 50 فرد بدون وجود سابقه اختلال بینایی و تشنج وارد مطالعه شدند شامل 25 نفر مبتلا به lebers congenital amaurosis و 25 نفر که سالم و بعنوان گروه شاهد بودند. دو گروه تحت erg و vep و eog قرار گرفتند و نتایج ب...
background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...
An investigation into the technical and commercial feasibility of computer-based interactive simulation of the human heart was conducted. An experimental research application was developed and served as a proof of concept for the simulation models during the research phase. The follow-on development phase will be directed towards a pre-production prototype of a virtual heart organ. The prototyp...
