The data in this directory have been contributed by Dr. Thomas Penzel of
Phillips-University, Marburg, Germany. See the
announcement of CinC Challenge
2000 for details on the competition for which these data have been assembled
here.
If you wish to download all of the files in this directory without selecting
each one individually, try using a utility for batch HTTP transfers such as
wget, available here in source form for all versions of UNIX and
as a precompiled binary for MS-Windows. Most Linux distributions include
wget. Once you have installed wget, retrieve these files
using
wget -r -np http://www.physionet.org/physiobank/database/apnea-ecg/
(or substitute the name of a nearby PhysioNet
mirror for www.physionet.org above). The files in this directory
occupy 583 megabytes.
The data consist of 70 records, divided into a learning set of 35
records (a01 through a20, b01 through b05,
and c01 through c10), and a test set of 35 records
(x01 through x35), all of which may be downloaded from this
page. Recordings vary in length from slightly less than 7 hours to nearly
10 hours each. Each recording includes a continuous digitized ECG signal,
a set of apnea annotations (derived by human experts on the basis of
simultaneously recorded respiration and related signals), and a set of
machine-generated QRS annotations (in which all beats regardless of type have
been labeled normal). In addition, eight recordings (a01 through
a04, b01, and c01 through c03) are
accompanied by four additional signals (Resp C and Resp A,
chest and abdominal respiratory effort signals obtained using inductance
plethysmography; Resp N, oronasal airflow measured using nasal
thermistors; and SpO2, oxygen saturation).
Several files are associated with each recording. The files with names of the
form rnn.dat contain the digitized ECGs (16 bits per sample,
least significant byte first in each pair, 100 samples per second, nominally
200 A/D units per millivolt). The .hea files are (text) header files
that specify the names and formats of the associated signal files; these header
files are needed by the software available from this site. The .apn
files are (binary) annotation files, containing an annotation for each minute
of each recording indicating the presence or absence of apnea at that time;
these are available for the 35 learning set recordings only. The qrs
files are machine-generated (binary) annotation files, made using sqrs125, and provided for the
convenience of those who do not wish to use their own QRS detectors. Please
note that the .qrs files are unaudited and contain errors. You may wish to correct these errors (if
you do, please send your corrections
to us). Otherwise, you may use these annotations in uncorrected form if
you wish to investigate methods of apnea detection that are robust with respect
to small numbers of QRS detection errors, or you may ignore these annotations
entirely and work directly from the signal files. Further information about
the annotation files, including interpretations of the annotation types (codes)
and details of how the .qrs files were created, are available here.
In April 2013, Chiu-wen Wu reported that training set control
records c05 and c06 come from the same original recording
(c05 begins 80 seconds later than c06). The slightly
different descriptions of these records
in additional-information.txt suggest
that c06 may have been a corrected version of c05.
The eight records that include respiration signals have several additional
files each. The four respiration-related signals are combined in a file named
rnnr.dat, which has its own header file
(rnnr.hea), as well as a header file named
rnner.hea, which (when used with software such as WAVE or
WVIEW) allows you to examine the ECG and the respiration signals
side-by-side.
Finally, if you are running Linux and have installed WAVE, you may click on the
.xws file associated with each record to view that record without
downloading it first. WAVE and the related
WFDB software package may be downloaded from this site.
