Combined measurement of ECG, Breathing and Seismocardiograms (CEBS database)

The purpose of the database was twofold: (1) To check if slight errors in the detection of the RR time series when measuring it using two different leads are influenced by breathing. (2) To compare the RR time series obtained from the ECG and its surrogate measure obtained from the seismocardiogram or SCG (and to optimize beat detectors for SCG).

To construct the database, 20 presumed healthy volunteers were measured. Information of the subjects is summarized in the info.txt file. During the measurement, the subjects were asked to be very still in supine position on a comfortable conventional single bed and awake. After attachment of sensors, we recorded the basal state of the subjects by measuring during 5 minutes (records b001 to b020) After that, the subjects started to listening classical music during approximately 50 minutes (records m001 to m020) Finally, we monitored all subjects 5 minutes more after the music ended (records p001 to p020).
