This database, from the Czech Technical University (CTU) in Prague and the University Hospital in Brno (UHB), contains 552 cardiotocography (CTG) recordings, which were carefully selected from 9164 recordings collected between 2010 and 2012 at UHB.

The CTG recordings start no more than 90 minutes before actual delivery, and each is at most 90 minutes long. Each CTG contains a fetal heart rate (FHR) time series and a uterine contraction (UC) signal, each sampled at 4 Hz.

The priority was to create as homogeneous a set as possible; thus only recordings fulfilling the following criteria were included:

Additional parameters were collected for all recordings, and are available in the (text) .hea files of the records:


PhysioNet thanks Václav Chudáček, Jiří Spilka, Miroslav Burša, Michal Huptych, and Lenka Lhotská at CTU, and Petr Janků and Lukáš Hruban at UHB, who created this data set, for making it freely available to the worldwide research community via PhysioBank. Special thanks to Václav Chudáček for coordinating the contribution and data transfer, and for his careful attention to ensure the quality of these records.

The creators of this database would like to thank Philips Healthcare for providing software for extraction and transformation of the CTG data from the OB TraceVue system to an open format.
