CONTEXT Recently, the implantable cardioverter-defibrillator (ICD) has been promoted for prevention of sudden death in hypertrophic cardiomyopathy (HCM). However, the effectiveness and appropriate selection of patients for this therapy is incompletely resolved. OBJECTIVE To study the relationship between clinical risk profile and incidence and efficacy of ICD intervention in HCM. DESIGN, SE...

The paddy production in Malaysia is characterised as small-scale agriculture, with modest plots of less than 2 ha and approximately 194,000 farmers employed. Majority these primarily rely on low-income agricultural production. This situation was exacerbated by the COVID-19 pandemic first quarter 2020, resulting a 3.11% reduction (17.03 million tonnes) overall output across Southeast Asia. Rural...

the real business cycle theory was applied to investigate the hypothesis of cyclical agreeable treatment of real wages, for men and women work force, in the iranian agricultural sector for the period of 1971-2006. on the basis of this theory, the impacts of supply side shocks (productivity and oil income shocks), are anticipated on the fluctuations of the real wages. the dominant effect of supp...

Implantable cardioverter-defibrillators (ICDs) have revolutionized the treatment of patients at risk for sudden cardiac death. In the nearly 3 decades since the first human ICD implant,1 millions of devices have been implanted worldwide and innumerable lives have been saved. Successful resuscitation of a potentially lethal ventricular arrhythmia by an ICD system depends on successful arrhythmia...

Rapid changes in technology can have a sudden and differential impact on cost components of variants within product lines such as computers, printers, digital cameras and cellular phones. How should retailers react to such changes? We address this issue by answering three questions. First, when the costs of specific product components change (perhaps, precipitously), how should retailers adapt ...

An increasing number of cardiac electrophysiologists are fortunate not to have endured the challenges of implanting monophasic waveform cardioverterdefibrillators (ICDs). With early technology, ICDs were routinely tested during the implantation procedure and then again before discharge, with a not-infrequent need for system revisions. With transvenous, high-output devices and biphasic shocks, t...

Ventricular arrhythmias are an important cause of cardiovascular morbidity and mortality, particularly in those with structural heart disease, inherited cardiomyopathies, and channelopathies. The goals of ventricular arrhythmia management include symptom relief, improving quality of life, reducing implantable cardioverter defibrillator shocks, preventing deterioration of left ventricular functi...

Sudden collapse of a compact object, or coalescence of a compact binary, can generate an unsteady relativistic wind that lasts for a few seconds. The wind is likely to carry a high magnetic field; and its Lorentz factor depends on the extent to which it is ’loaded’ with baryons. If the Lorentz factor is ∼ 100, internal dissipation and shocks in this wind produce a non-thermal gamma-ray burst, d...
