Aims: Atrial fibrillation/atrial flutter (AF/AFL) is a critical public health issue worldwide, and its epidemiological patterns have changed over the decades.This work aimed to assess the global trends of AF/AFL and attributable risks from 1990 to 2019.Methods and results: The present study utilized data from the Global Burden of Disease Study 2019
Supernormal Conduction and Suppression of Spatial Discord in Alternans of Cardiac Action Potentials
Spatially discordant alternans (DA) of action T Shirt potential durations (APD) is thought to be more pro-arrhythmic than concordant alternans.Super normal conduction (SNC) has been reported to suppress formation of DA.An increase in conduction velocity (CV) as activation rate increases, i.e.a negative CV restitution, is widely considered as hallma
A tower of hidden sectors: a general treatment and physics implications
Abstract An analysis of a tower of hidden sectors coupled to each other, with one of these hidden sectors coupled to the visible sector, is given and the implications of such couplings on physics in the visible sector are investigated.Thus the analysis considers n number of hidden sectors where the visible sector couples only Basketball to hidden s
