I mplantable cardioverter-defibrillators (ICDs) are well documented to save lives in many patient groups for primary and secondary prevention; however, although the ICD is highly effective at preventing sudden death, everyone will die eventually, whether of underlying heart disease or other terminal illness such as malignancy. As the population of patients living with ICDs expanded, case report...

oil prices may be having a direct and indirect effect through the exchange rate on the price of agricultural commodities. in this paper, the impact of world oil prices and exchange rate shocks on prices of specific agricultural commodities including wheat, corn, soybeans and sunflowers in iran is discussed. for this purpose, vector autoregressive model with monthly data over the period 2010-199...

in this research, potential effects of oil and monetary policy shocks on economic growth of iran are examined and share of each of them on economic growth are calculated during 1974-2006 period and potential mutual effects of those shocks by using the vector auto regressive (var) model are analysed. results of this research show that oil shocks significantly affected the economic growth in iran...

introduction: the aim of this study was to evaluate the efficacy of combined intratympanic and systemic steroid therapy compared with systemic steroid therapy alone in idiopathic sudden sensorineural hearing loss (issnhl) patients with poor prognostic factors.     materials and methods: seventy-seven patients with sudden sensorineural hearing loss (ssnhl) who had at least one poor prognostic fa...

BACKGROUND In US clinical practice, many patients who undergo placement of an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death receive dual-chamber devices. The superiority of dual-chamber over single-chamber devices in reducing the risk of inappropriate ICD shocks in clinical practice has not been established. The objective of this study was to compar...

Measurement tools for high speed air flow are sought both in industry and academia. Particular interest is shown in air flows that exhibit aerodynamic shocks. Shocks are accompanied by sudden changes in density, pressure, and temperature. Optical detection and characterization of such shocks can be difficult because the medium is normally transparent air. A variety of techniques to analyze thes...

BACKGROUND Brugada syndrome is an arrhythmogenic disease characterized by an increased risk of sudden cardiac death (SCD) by ventricular fibrillation. At present, an implantable cardioverter-defibrillator (ICD) is the recommended therapy in high-risk patients. This multicenter study reports the outcome of a large series of patients implanted with an ICD for Brugada syndrome. METHODS AND RESUL...

The purpose of this study was to predict implantable cardioverter defibrillator (ICD) shocks using demographic and clinical characteristics in the first year after implantation for secondary prevention of cardiac arrest. A prospective design was used to follow 168 first-time ICD recipients over 12 months. Demographic and clinical data were obtained from medical records at the time of ICD insert...
