Conclusion: After observing the effects of various detrending types to a signal some points became
clear..
In Frequency Domain
1-VLF band power decreases with increasing detrending order, amount of reduction in second and thirt
order is bigger then first order.
2-Power Percentage of VLF band decreases this causes the icrementation in Power Percentage of other
band frequencies
3-Power increases with smoothing priors’ term Lambda
In Time Domain
1-SDNN decreases with some amounts based on reduction amount Third order>Second Order > First
Order and, SDNN increases with Lambda of Smoothing Priority
2- SDTD HR decreases with some amounts based on reduction amount Third order>Second Order > First
Order and, SDNN increases with Lambda of Smoothing Priority
3-TINN increases with the order of Detrending,some samples have same TINN number in second and
thirt orders so it can be ignored,TINN increases with increasing Lambda,usually” amount of decresing”
increases with increasing Lambda
4-HRV triangular index Decreases ,”amount of decreasing” increases with “increasing”degree of
detrending,”decreasing” amount of lambda.
