Over 100 fifteen-minute two-lead ECG recordings (many excerpted from other databases), with onset, peak, and end markers for P, QRS, T, and (where present) U waves of from 30 to 50 selected beats in each recording.
Each of the 105 records consists of a (text) header file, a (binary) signal file, and up to 9 (binary) annotation files, identified by suffix:
|.hea||header file, describing signal file contents and format|
|.atr||reference beat annotations from original database (not available in all cases)|
|.man||reference beat annotations for selected beats only|
|.q1c||manually determined waveform boundary measurements for selected beats (annotator 1 only -- second pass)|
|.q2c||manually determined waveform boundary measurements for selected beats (annotator 2 only -- second pass; available for only 11 records)|
|.qt1||manually determined waveform boundary measurements for selected beats (annotator 1 only -- first pass)|
|.qt2||manually determined waveform boundary measurements for selected beats (annotator 2 only -- first pass; available for only 11 records)|
|.pu||automatically determined waveform boundary measurements for all beats (based on both signals)|
|.pu0||automatically determined waveform boundary measurements for all beats (based on signal 0 only)|
|.pu1||automatically determined waveform boundary measurements for all beats (based on signal 1 only)|
