Background. Adenosine is well known to depress atrioventricular (AV) nodal conduction, but the potential interactions between adenosine and functional AV nodal properties have not been explored. The purpose of the present study was to determine (1) whether exogenous adenosine modifies the ratedependent properties of the AV node, (2) to what extent such changes underlie the actions of adenosine ...

Using His bundle recordings and ventricular stimulation retrograde conduction was studied in 57 cases of complete AV block. VA conduction was observed in 13 patients. Of the 13, 12 had AV block distal to H, and during cardiac pacing 5 of them showed a retrograde His bundle potential. In all cases the AV node-His pathway was implicated in the transmission of the retrograde impulse. There was no ...

Film, video, and TV have become a predominant medium, but most audiovisual (AV) material being part of our cultural heritage is kept in archives without the possibility of appropriate access for the public. Although digitalization of AV objects in conjunction with AV analysis is making progress, content-based retrieval remains difficult because of the so called semantic gap. The Mediaglobe proj...

Determinants of nonfunctional arteriovenous (AV) access, including timing of AV access creation, have not been sufficiently described. We studied 29 945 patients who had predialysis AV access placement and were included in the French REIN registry from 2005 through 2013. AV access was considered nonfunctional when dialysis began with a catheter. We estimated crude and adjusted odds ratio (OR) w...

We give three applications of a recently-proven "Decomposition Lemma," which allows one to count preimages certain sets permutations under West's stack-sorting map $s$. first enumerate the permutation class $s^{-1}(\text{Av}(231,321))=\text{Av}(2341,3241,45231)$, finding new example an unbalanced Wilf equivalence. This result is equivalent enumeration sortable by ${\bf B}\circ s$, where B}$ bub...

449 Letter to the Editor I read with great interest the article by Głowiński et al.1 The study focused on the issue of whether arteriovenous (AV) fistula closure among recipients with successful kidney transplants had an effect on cardiac function. The authors concluded that AV fistula closure in kidney recipients with well-functioning renal grafts had no significant beneficial effect on the he...

BACKGROUND Use of rate adaptive atrioventricular (AV) delay remains controversial in patients with biventricular (Biv) pacing. We hypothesized that a shortened AV delay would provide optimal diastolic filling by allowing separation of early and late diastolic filling at increased heart rate (HR) in these patients. METHODS 34 patients (75 ± 11 yrs, 24 M, LVEF 34 ± 12%) with Biv and atrial paci...

This study examines how native language (L1) experience affects audio-visual (AV) perception of nonnative (L2) speech. Mandarin, Korean, and English perceivers were presented English CV syllables containing fricatives with 3 places of articulation: labiodentals nonexistent in Korean, interdentals nonexistent in Korean and Mandarin, and alveolars occurring in all L1s. The stimuli were presented ...

The increasing availability of digital music has created a demand for organizing and retrieving the music. Thus, a new multi-disciplinary research area called music information retrieval, MIR, has emerged. An important part of the content-based field of the research area is to extract musical features, such as tempo or modality, directly from the content, i.e. the audio. This thesis is an evalu...
