Sustained ventricular tachycardia (VT) is an important cause of morbidity and sudden death in patients with heart disease.1 Implantable cardioverter-defibrillators (ICDs) terminate VT episodes, reducing the risk of sudden death. Recurrent VT develops in 40% to 60% of patients who receive an ICD after an episode of spontaneous sustained VT. A first episode of VT occurs in 20% of patients within ...

in this paper, we examine influence oil shocks on macroeconomic variables and dutch disease phenomena when these variables encountered positive oil revenue shocks. statistical model which is copula approach is used to show when iran's macroeconomic variables encountered positive oil revenue casus dutch disease and oil revenue has non-symmetric influence on the growth economic. in another w...

introduction: natural and unexpected death that happens within less than one hour of first symptom occurrence is called sudden death. cardiovascular diseases are the main known reason of sudden death and more than 75% of sudden deaths in athletes are assigned to it. here we reported the autopsy results of all cases with sudden death following exercise that were referred to forensic center of te...

regular participation in intensive physical exercise is associated with electro-morphological changes in the heart.   this benign process is called athlete’s heart. athlete’s heart resembles few pathologic conditions in some aspects. so differentiation of these conditions is very important which otherwise may lead to a catastrophic event such as sudden death. the most common causes of sudden de...

Financial frictions are a central element of most of the models that the literature on emerging markets crises has proposed for explaining the Sudden Stop phenomenon. To date, few studies have aimed to examine the quantitative implications of these models and to integrate them with an equilibrium business cycle framework for emerging economies. This paper surveys these studies, viewing them as ...

OBJECTIVES The purpose of this study was to determine the mechanisms of sudden death (SD) in patients with ventricular tachyarrhythmias (ventricular tachycardia/ventricular fibrillation [VT/VF]) treated with an implantable cardioverter defibrillator (ICD). BACKGROUND Despite ICD therapy, some patients with VT/VF still die suddenly. Optimal ICD use requires determination of the mechanisms of t...

Based on the results of several large, randomized, clinical trials, implantable cardioverter defibrillators (ICDs) have become a ‘‘gold standard’’ therapy in prevention of sudden cardiac death. Under current guidelines, ICDs are implanted in patients who survived cardiac arrest or hemodynamically unstable ventricular tachycardia, as well as in primary prevention, mainly for those with ischemic ...

Sudden cardiac death (SCD) is a vital public health issue, accountable for almost 50% of all cardiovascular deaths. In the last three decades, SCD was leading cause 230000 to 350000 deaths per annum in United States. Ventricular arrhythmias account 25% 36% witnessed sudden arrests (SCA) at home and 38% 79% SCA public. The goals ventricular arrhythmia management include symptom relief, improving...
