✦ Synopsis
The unevident variability during a 30-rain 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: (1) Generally each time series, related to the many interval values measured, shows that its variability is different from that of the R-R intervals. (2) In particular Bazzett's formula, which provides the widely used "corrected QT interval", has to be amended.
