AHA Database Sample Excluded Record

These files are not part of the AHA Database. They are derived from a sample given to us by the creators of the AHA Database. The original recording had been a candidate for inclusion in the database and was digitized and annotated using the same methods used for the AHA Database records. After the annotation process was complete, the recording was excluded from the AHA Database since it was found to contain ectopy of a higher grade than the class for which it had been chosen as a candidate.

The WFDB Software Package includes a set of converters that can translate between the formats used for the AHA database and the standard formats used for PhysioBank databases. These converters were used to prepare the files in this directory.

As for the records in the AHA Database, the data consist of a 3-hour recording of two ECG signals, for which the last 30 minutes are annotated beat-by-beat. From the original data, we have prepared record 0001, containing the entire 3-hour recording, and record 0201, containing the last 35 minutes only.

Further information about the AHA Database is available here.
