Abstract
We present here a QT database designed jbr evaluation of algorithms that detect waveform boundaries in the EGG. The dataabase consists of 105 fifteen-minute excerpts of two- channel ECG Holter recordings, chosen to include a broad va- riety of QRS and ST- T morphologies. Waveform bounda,ries for a subset of beats in, these recordings have been manually determined by expert annotators using an interactive graphic disp1a.y to view both signals simultaneously and to insert the annotations. Examples of each m,orvhologg were inchded in this subset of uniaotated beats; at least 30 beats in each record, 3622 beats in all, were manually a:anotated in Ihe database. In 11 records, two indepen,dent sets of ennotations have been inchded, to a.llow inter-observer variability slwdies. The Q T Databnse is available on a CD-ROM in the format previously used for the MIT-BJH Arrhythmia Database ayad the Euro- pean ST-T Database, from which some of the recordings in the &T Database have been obtained.Keywords
