This is a collection of 100 six, seven, and eight-channel records, each 10 minutes long, to be used as a training set for the PhysioNet/Computers in Cardiology Challenge 2010 (Mind the Gap). In each of these records, the final 30 seconds of one signal has been replaced by zeroes (i.e., a flat signal). As in the test sets of the Challenge, the problem to be solved is to reconstruct the missing data as accurately as possible, using all of the contextual information.

In this training set, the missing samples from each record are included in the (text) files with the suffix .missing. Challenge participants will need to create and submit files containing their reconstructions of missing samples in the test set records in the format of these text files in order to receive scores in the Challenge.

Records in this training set were renamed; their original names can be found in MAP.
