This database includes 84 long-term ECG recordings of subjects with
paroxysmal or sustained atrial fibrillation (AF). Each record
contains two simultaneously recorded ECG signals digitized at 128 Hz
with 12-bit resolution over a 20 mV range; record durations vary but
are typically 24 to 25 hours. The qrs annotations were
produced by an automated QRS detector; all detected beats (including
occasional ventricular ectopic beats) were labelled N.
The AF Termination Challenge Database
consists of 80 one-minute excerpts of a subset of these records (those
numbered 00 through 75). As a guide to selecting the excerpts, "T"
annotations were inserted manually in the qrs annotation
files of this subset of the records, to mark spontaneous terminations
of AF episodes with durations of at least one minute.
The original recordings were collected and contributed to PhysioNet by
Steven Swiryn and his colleagues at Northwestern University. They
were digitized and automatically annotated at Boston's Beth Israel
Deaconess Medical Center. Steven Swiryn and George Moody annotated
the AF terminations.
