The study presents a method for quantification of the respiratory effect on the thoracic impedance signal. We used measurements with 18 simultaneously scanning impedance signal locations. Elimination of breathing is based on the assumption that the neck and limb impedance signal measures only the variability in systemic blood pressure and is not affected by respiration. The results show approximately...
The aim of this study was to evaluate and compare changes of arterial blood pressure, heart rate and thoracic impedance cardiography parameters during head-up tilt table test and to discuss possible negative-positive influence to diagnostic contribution. Results demonstrate that blood pressure parameters do not drop dramatically while tilting within healthy subjects. On the contrary, thoracic impedance...
