- Title: Spectrum analysis of Heart Rate Variability (HRV)
- Description: This project is part of our ongoing research regarding estimation of high frequency heart rate variability (HF-HRV) or respiratory sinus arrhythma (RSA) that is used as a proxy of parasympathetic cardiac regulation. RSA refer to variations in heart rate that follow the respiratory cycle: when we inhale the heart beats faster and when we exhile heart beats slower. HF-HRV is commonly estimated in a frequency range between 0.12-0.40Hz, that is the range within we normally breathes. In this project we will use a classic "tilt" manouver to affect RSA. The tilt includes two conditions: supine position (laying down) and upright position. Genarally parasympathetic cardiac regulation, HF-HRV, is higher in supine position that in upright position. The aim is to study if modern robust spectral analysis methods (such as multitapers), better differentiates between the two conditions compared to traditional spectral analysis. Cross-spectral analysis between the HRV and the breathing signals can also be used as a refined technique for analyzing the HRV power. The project is a collaboration between Mathematical statistics and Occupational- and environmental medicine at Lund University. Relevant courses are stationary stochastic processes, time series analysis and signal processing.
