Abstract
The aim of this project was to investigate if the autonomic cardiacmodulation is reflected in the morphology of individual QRS complexes.ECG recordings from 20 healthy subjects and 18 subjects diagnosedwith CRPS type I during a tilt table test were analysed. Furthermore,ECG recordings from 11 healthy subjects with capsaicin inducedpain were analysed. Two features were extracted from eachQRS complex; the steepest ascending slope of the QRS complex,and the scale where a wavelet adapted to each subject had the largestcorrelation with the QRS complex. The outcome was compared tothe mean NN interval and standard deviation of the NN intervals(SDNN).
