The analysis is based on measurements of 11 patients with pacemaker. In each measurement, there are at least 4 abrupt changes of RR preset by the pacemaker. The QT/RR coupling was described by a 3 parameters transfer function (TRF) selected on the basis of a statistical analysis of performances of different TRF models. We found that our model is by far the best in its class: with more parameters (higher order models) the residuals remain almost the same while the extra parameters display variability much larger than that of our parameters. For all measurements, our TRF model describes more than 70 % of QT variability."@en . . "000253467000233" . "Vondra, Vlastimil" . . "418409" . "Jur\u00E1k, Pavel" . . "2007-08-23+02:00"^^ .
