Identifying predictors of electrical storm in patients with implantable cardioverter-defibrillators (ICDs) could help identify those at risk and reduce the incidence of this emergency situation, which has a detrimental effect on mortality and morbidity in patients with ICDs. This retrospective study sought to determine the prevalence and predictors of(More)
BACKGROUND Hospitals are the most costly operational and really important units of health system because they consume about 50%-89% of total health resources. Therefore efficient use of resources could help in saving and reallocating the financial and physical resources. OBJECTIVES The aim of this study was to obtain an overview of hospitals' performance(More)
BACKGROUND Understanding the predictors of appropriate implantable cardioverter defibrillator (ICD) therapy could help to better identify candidates for ICD implantation. METHODS One hundred and sixty two patients with ICD (111 with coronary artery disease [CAD] and 51 with dilated cardiomyopathy [DCM]) were included in the study. Clinical,(More)
As Medical sciences become more advanced and grow each day, so do the challenges of medical education. To overcome the new obstacles which are an inseparable part of science evolution, it is necessary to renew and improve the educational system .Achieving this, requires individuals who are educated in the new methods of learning and therefore can lead(More)
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(More)
INTRODUCTION It has been found that the decision-making process in medicine is affected, to a large extent, by one's experience, individual mentality, previous models, and common habitual approaches, in addition to scientific principles. Evidence-based medicine is an approach attempting to reinforce scientific, systematic and critical thinking in physicians(More)
The aim of this study was to compare two surgery methods including radial shortening and radial shortening combined with vascularized bone graft for treatment of stage II or IIIa of Kienböck's disease. It is a randomized, controlled clinical trial, which was carried out in 2011-2013. Twenty-four patients were assigned equally to radial shortening group (A)(More)
ECG in sinus rhythm with ventricular preexcitation and changing QRS morphology was seen that was initially interpreted as the multiple accessory pathway from elsewhere. (Figure 1A). The following mechanisms are potentially involved in the electrogenesis of changing QRS morphology in WPW syndrome: 1) multiple accessory pathways 1 ; 2) simultaneous occurrence(More)
BACKGROUND There is a growing tendency toward application of human amniotic membrane (HAM) as a biologic substitute in various tissue injuries where a significant tissue loss is a matter of concern. In gastrointestinal injuries especially duodenal ones, some potential limitations in current surgical techniques contribute to not fully acceptable healing(More)
