Is [ The genetic relation of four ethnic populations in China 's Guizhou revealed by sequence variations of mtDNA D-loop ]?
Yi and Tujia population are very closely related, the reason may be that they either originate from a common ancestry or frequently undergo the gene exchanges and admixtures. The genetic relationship between Tujia and Gelao population is nearer, perhaps because they have settled in the adjacent regions. Dong and Yi population show the farthest genetic relationship, this is probably due to their different historical origins and geographic segregation.
Abnormal septal motion, assessed by the presence of SF, is a mechanism amenable to CRT correction. Its correction is associated with a higher likelihood of CRT response in HF patients with long-standing AF. This could improve the selection of candidates to CRT in a subgroup with particularly poor response and long-term prognosis.
