Tuberous Sclerosis is a genetic condition characterized with multiple non-cancerous tumor growths throughout the body. While arrhythmias are commonly seen in these patients, predominance of appear to be irregular atrial and ventricular ectopy as most common manifestation. In our case we describe patient both organized ( typical flutter, atypical flutter ) monomorphic tachycardia. A pleasant 22 ...

We present a precise theoretical prediction for the decay width of the bound state of two electrons and a positron (a negative positronium ion), Γ(Ps−) = 2.087 085(12)/ns. We include O(α) effects of hard virtual photons as well as soft corrections to the wave function and the decay amplitude. An outcome of a large-scale variational calculation, this is the first result for second-order correcti...
