This is a collection of 100 six, seven, and eight-channel records, each 10 minutes long, to be used as a test 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 In each of these records, the final 30 seconds of one signal has been replaced by zeroes (i.e., a flat signal).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 other 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 test set, the missing samples from each record are included in the (text) files with the suffix .missing, which were not available to participants until after the conclusion of the Challenge.

For additional information, see the Challenge 2010 home page.
