Ballistocardiography with breathing disorderes

Tha dataset contains ballistocardiography signals together with ECG and calculated first Cartan curvature (files denoted as c#.csv, where # is the number corresponding with the measurement #.txt). We studied changes in the signals related with breath holding.

The BCG sensor dataset is obtained from twenty tested individuals. The schedule of measuring was in two types (V1 and V2) described in description. Every breath-holding was done for the time of the approximatelly 30 seconds. For measurement a force plate in the form of bed was used. The force plate had four tensometers embedded in its four legs. Each tensometer could measure the force in three orthogonal directions with a precision of up to 0.1 N. Therefore, 12 force signals were obtained. The ECG signal was measured simultaneously with the force measurement. All the signals were registered using a 24-bit AD converter with a sampling rate of 1 kHz. Measurement took place in laboratory at Faculty of Science, University of Hradec Králové, Czech republic.
