Editorials Incessant ventricular tachycardia: a lost case or new hope? Ventricular tachycardia remains a difficult problem in spite of all the recent advances. Anti-arrhythmic drugs continue to fail in more and more trials, and it is unlikely that we will have effective (and safe) drugs based on new principles in the near future'' 1. In contrast, the results of implantable cardioverter/ defibri...

assessing the potential impacts of 21st-century climate change on species distributions and ecological processes requires climate scenarios with sufficient spatial resolution. in this study we projected future changes in maximum temperature and minimum temperature under cmip3 sres and cmip5 rcps scenarios with two station-based datasets (arazkoseh and nodeh) of the eastern golestan province. ch...

There are many treatment modalities available to acutely terminate incessant ventricular tachycardia with variable success rates, but some cases tend to prove refractory to all of them. We report a 59-year-old woman presenting with incessant ventricular tachycardia. Echocardiography revealed a large true apical aneurysm and severe left ventricular dysfunction. The arrhythmia was controlled in t...

It has been argued recently that the combination of risk aversion and an uncertainty distribution of future temperature change with a heavy upper tail invalidates mainstream economic analyses of climate change policy. A simple model is used to explore the effect of imposing an upper bound on future temperature change. The analysis shows that imposing even a high bound reverses the earlier argum...
