The relation between SVEs/SVTs in 24 h and quartiles of NT-proBNP/TnT. The numbers of SVEs and SVTs were transformed by lg(n + 1). a SVEs/24 h and NT-proBNP quartiles. b SVTs/24 h and NT-proBNP quartiles. c SVEs/24 h and TnT quartiles. d SVTs/24 h and TnT quartiles. The boxes illustrate median, 25th and 75th percentiles. Vertical lines include the 10th and 90th percentiles. Abbreviations NT-proBNP N terminal pro B type natriuretic peptide, SVEs supraventricular extrasystoles, SVTs supraventricular tachycardias, TnT troponin T
