Abstract
Time of sets between changes in heart rate, blood pressure and breathing are important to understand when developing cardiovascular models. This study recorded six subjects breathing at 6 arid 12 breaths per minute, with and without breathing resistance. RR intervals and systolic pressure (SP) levels were extracted from ECG and Finapres signals; breathing was measured using magnetometers. Time ofsets were calculated from the position of peaks in the cross-correlated signals. ANUVAs showed signifcant effects with breathing resistance for the time offsets relative to the breathing signal. ANOVAs showed significant effects with breathing frequency for time offsets relarive to changes in SP levels.
