A 25-year-old man with idopathic atrial flutter and high grade atrioventricular (AV) block is described. Postcardioversion, sino-atrial (SA) and AV nodal dysrhythmias occurred. Treadmill exercise during atrial flutter increased AV conduction to 2:1, and normalized SA and AV nodal function following cardioversion. A neurogenic basis for these arrhythmias is hypothesized.

Previous cross-sectional research has shown that prelingually deaf children who use cochlear implants (CIs) show enhancement when speech is presented in an audiovisual (AV) format compared to auditory-alone (A-alone) and visual-alone (V-alone) formats. The purpose of the present study was to investigate the development of AV integration skills in this clinical population. We examined the AV sen...

Women with connective tissue diseases increase risks of obstetric complications during pregnancy. Especially, women who have anti-SSA/Ro and anti-SSB/La auto-antibodies increase the risk of developing fetal atrioventricular (AV) block. It is difficult to indentify fetal AV block in the early stage of the disease, which is consequently found after the establishment of complete AV block as the fo...

Syftet med det här arbetet har varit att utveckla en praktisk Man-In-The-Middle-attack mot trådlösa klienter på NetLogon-systemet vid Linköpings Universitet. Målsättningen har varit att attacken skall ske så transparent som möjligt ur offrets synvinkel. Attacken använder DNS-spoofing och en MITM-metod med förfalskade avsändaradresser genom packet injection. Vi har implementerat ett fungerande v...

No data are available for the direct effect of C-type natriuretic peptide (CNP) on atrioventricular (AV) conduction in mammalian hearts. Thus we studied the dromotropic effects of CNP-22 injected into the AV node artery in autonomically decentralized hearts in open-chest, anesthetized dogs. CNP decreased AV interval (AV conduction time) in a dose-dependent manner with increase in coronary arter...

In this paper we present a contextual representation model of audiovisual (AV) documents for AV information systems. In the rst part, we study AV medium, and show that AV intra-document context is always related to a user task seen as a general description task. We then present the AI-Strata model for AV description: audiovisual units (pieces of AV documents) are annotated with annotation eleme...

In the Essential Health Benefits, Actuarial Value, and Accreditation Notice of Proposed Rulemaking published in the Federal Register, HHS proposes the use of an AV Calculator to determine levels of coverage for non-grandfathered health insurance plans offered in the individual and small group markets, both inside and outside of the Affordable Insurance Exchanges (Exchanges). Section 1302(d)(2)(...

Complete atrioventricular (AV) block is defined as a dissociation of atrial and ventricular activities. Complete AV block that occurs during the perioperative period is difficult to reverse and usually requires implantation of a pacemaker. Propofol does not affect a normal AV conduction system but may act as a trigger for AV block. It can also potentiate vagal stimulation factors and reduce sym...

In atrioventricular (AV) block patients, AV synchrony can be restored by implanting DDD pacing systems if an individual optimization of the pacemaker AV delay is performed. If the latter is neglected and the AV delay is left at nominal settings, adverse hemodynamic effects may develop. Therefore, several methods were proposed to calculate or to estimate the individual hemodynamically optimal le...
