Abstract (Swedish)
In this master thesis the correlation between heart rate variability and respiration is analysed in order to examine the possibility of finding differences between individuals under different levels of work related stress. A total number of 24 individuals, divided into groups under low stress, high stress and those formerly exhausted, had their heart rates and respirations recorded. Cross-spectral analysis of respiration and heart rate variability in the time-frequency domain was used to extract information of how the two signals correlate to each other. A set of different methods to create time-frequency representations were implemented and evaluated by applying them to simulated signals. The best performing methods were then applied to... (More)

A set of different methods to create time-frequency representations were implemented and evaluated by applying them to simulated signals. The best performing methods were then applied to the recorded data and the resulting cross-spectra were analysed.
A big difference could be seen in how well the time-frequency analysis managed to separate the three different groups compared (Less)
