Characterization of refractory period extension by transcardiac shock.
BACKGROUND To better understand the refractory period extension (RPE) produced by transcardiac shocks and its possible role in defibrillation, we measured RPE under various experimental conditions. METHODS AND RESULTS Using ventricular pacing in pentobarbital-anesthetized dogs, we characterized RPE in relation to the anatomic site of pacing, the local voltage gradient (LVG) produced by the sh...
متن کاملVentricular refractory period extension caused by defibrillation shocks.
In pentobarbital-anesthetized dogs, transcardiac shocks of up to 30 J or pacing stimuli were delivered to myocardial tissue at different times in the electrical cycle. When delivered midway or later into electrical systole, shocks, but not pacing stimuli, greatly extended the refractory period as determined by left ventricular pacing. There was a positive correlation between both the shock ener...
متن کاملRefractory Celiac Disease
Refractory celiac disease (RCD) is when malabsorption symptoms and villous atrophy persist despite strict adherence to a gluten free diet (GFD) for more than 12 months and other causes of villous atrophy have been ruled out. RCD is considered a rare disease and almost exclusively occurs in adults. Persistent diarrhea, abdominal pain, weight loss are the most common symptoms in RCD. Also, anemi...
متن کاملFAILURE MECHANISMS OF REFRACTORY LININGS FOR NONFERROUS FLASH SMELTING FURNACES
Although the flash smelting technologies use different furnace designs, the refractory linings are exposed to very similar aggressive environments and, as a result, the corrosion analysis results on one type of furnace could be generally applied to other furnaces of similar high temperature processes. Particularities regarding the different chemistries of the pyrometallurgical process and opera...
متن کاملIntratympanic Injection of Dexamethasone and Electrocochleographic Data in Cases of Definite One Sided Refractory Meniere’s Disease
Introduction: Meniere’s disease (MD) is a disease of the inner ear that presents itself with repeated episodes of vertigo (96.2%), tinnitus (91.1%), and sensorineural hearing loss (87.7 %). In this article we sought to assess the effects of intratympanic (IT) injections of dexamethasone on definite cases of MD using electrocochleography (ECOG). Materials and Methods: In this hospital-based case...
