This database consists of 75 annotated recordings extracted from 32
Holter records. Each record is 30 minutes long and contains 12
standard leads, each sampled at 257 Hz, with gains varying from
250 to 1100 analog-to-digital converter units per millivolt. Gains for
each record are specified in its .hea file. The reference
annotation files contain over 175,000 beat annotations in all.
The original records were collected from patients undergoing tests for
coronary artery disease (17 men and 15 women, aged 18-80; mean age: 58).
None of the patients had pacemakers; most had ventricular ectopic beats.
In selecting records to be included in the database, preference was
given to subjects with ECGs consistent with ischemia, coronary artery
disease, conduction abnormalities, and arrhythmias; observations
of those selected included:
| Diagnosis | Patients |
|---|
| Acute MI | 2 |
| Transient ischemic attack (angina pectoris) | 5 |
| Prior MI | 4 |
| Coronary artery disease with hypertension |
7 (4 with ECGs consistent with left ventricular hypertrophy) |
| Sinus node dysfunction | 1 |
| Supraventricular ectopy | 18 |
| Atrial fibrillation or SVTA | 3 (2 with paroxysmal AF)
|
| WPW | 2 |
| AV block | 1 |
| Bundle branch block | 3 |
These diagnoses were confirmed by enzyme assays, coronary angiography,
electrophysiological study, and pressure monitoring where necessary.
For each record, the .hea file includes the patient's age, sex, diagnoses,
and a summary of features of the ECG. Each .hea file also includes a
patient number (1–32) that identifies the source recording; all records
with a given patient number were obtained from the same Holter recording.
For convenience, this information is also collected in the files
record-descriptions.txt and
files-patients-diagnoses.txt.
The annotations were produced by an automatic algorithm and then
corrected manually, following the
standard PhysioBank beat annotation
definitions. The algorithm generally places beat annotations in the middle
of the QRS complex (as determined from all 12 leads); the locations have not
been manually corrected, however, and there may be occasional misaligned
annotations as a result.
This database was contributed by the St. Petersburg Institute of
Cardiological Technics (Incart), St. Petersburg, Russia. The database was
initially developed by Viktor Tihonenko
(vmt@incart.ru) and Alexander
Khaustov (avk@incart.ru). Additional
verification was done by Sergey Ivanov and Alexei Rivin (Incart).
