Detecting and Quantifying T-Wave Alternans: The PhysioNet/Computing in Cardiology Challenge 2008 1.0.0

File: <base>/about-records.txt (3,948 bytes)
The table below indicates reference ranks and sources for each record in the
T-Wave Alternans Challenge Database (twadb).

Column 1 is the name of the record within the twadb.

Column 2 is the reference rank derived from the ranks assigned by challenge
entries.  High ranks correspond to records with larger amounts of TWA.
(Thus the record judged to contain the most TWA has a rank of 100, etc.)

Column 3 specifies the data collection from which each record originates,
which is one of:
      inc    St. Petersburg Institute of Cardiological Technics 12-lead
      	      Arrhythmia Database
      lts    Long-Term ST Database
      nsr    MIT-BIH Normal Sinus Rhythm Database
      ptb    PTB Diagnostic ECG Database (patients)
      ptbc   PTB Diagnostic ECG Database (healthy subjects)
      sdd    Sudden Cardiac Death Holter Database
      syn    synthesized ECGs with TWA
      sync   synthesized ECGs without TWA

Column 4 is the name of the original record from which the twadb record was
