Thus the WFDB library is considerably more than an ECG database interface. Among these multi-parameter databases are the MIT- BIH Polysomnographic Database, the MGH/Marquette Foundation Waveform Database, and the MIMIC Database. The WFDB library has evolved to support the development of numerous other databases that include signals such as blood pressure, respiration, oxygen saturation, EEG, as well as ECGs. The WFDB library is sufficiently general, however, to be useful for dealing with any similar collection of digitized signals, which may or may not be annotated. In February 1990, the predefined annotation set was expanded to accommodate the needs of the European ST-T Database (ESC DB). These functions were originally designed for use with databases of electrocardiograms, including the MIT-BIH Arrhythmia Database (MIT DB) and the AHA Database for the Evaluation of Ventricular Arrhythmia Detectors (AHA DB).

Records The databases for which the WFDB library was designed consist of a small number of records, each of which is quite large (typically a megabyte or more). These concepts include records signals, samples, and time and annotations. There are a few important concepts that should be well understood before going further. A standard set of such programs is included in the WFDB Software Package, and is described in the WFDB Applications Guide other documents describe the databases themselves, and existing programs that use them (see Appendix E , page 121, for information about obtaining these and related items).

For example, record names in the MIT DB are three-digit numbers, those in the AHA DB are four-digit numbers, and those in the ESC DB are four-digit numbers prefixed by the letter e. Records are identified by record names of up to 20 characters (the limit is MAXRNL, defined in ). These databases are therefore qualitatively different from those for which conventional database management software is written.
