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:
