The unit of amplitude for samples.

An integer in the range of 1 to ACMAX (a constant defined in `<ecg/ecgcodes.h>') inclusive, which denotes an event type.

A name associated with an annotation file. On writable UNIX and Macintosh file systems, the annotation file name is constructed from the annotator name by appending a `.' and the record name. On [..]

In this guide, a program that uses the DB library to do something.

The counter value (q.v.) that corresponds to sample 0. The base counter value is read by getbasecount, and set by setbasecount (or by any of the functions that read `header' files). If not define [..]

The sample value that corresponds to the baseline (isoelectric level or physical zero level) in the signal. This quantity may drift during the record for a variety of reasons, in which case the baseli [..]

A file containing data used to build a calibration list (q.v.).

A read-only medium used for distribution of the MIT-BIH and ESC databases, among others. CD-ROMs are physically identical in appearance to audio compact disks. CD-ROM readers are available for most mi [..]

The difference between counter values (q.v.) that are separated by an interval of one second. The counter frequency is constant throughout any given record. It may be undefined, in which case it is tr [..]

Those files (annotation files, `header' files, signal files, and calibration files) that are accessed via the DB library.
