A first step quantification by correlation techniques of the variability in some time intervals measured on the
Abstract:
The unevident variability during a 30-min period on intervals measured once every cardiac cycle was investigated by correlation techniques implemented on a digital computer, on normal healthy subjects from the "Politecnico/Ca' Granda VCG Database On Young Normal Subjects". Our most important conclusions are as follows: Generally each time series, related to the many interval values measured, shows that its variability is different from that of the R-R intervals. In particular Bazzett's formula, which provides the widely used "corrected QT interval", has to be amended.
