Characteristics of the ad-hoc datasets used for the prediction of sudden cardiac death or malignant ventricular arrhythmias.
| Name | Subjects included in the database | No. recordings | Type | Frequency |
|---|---|---|---|---|
| Massachusetts Institute of Technology-Beth Israel Hospital SCD Holter database (SCDH)22 | Recordings of subjects before SCD or sustained VT onset as well as a few seconds later. 18 subjects (8 female, 13 female, 2 unknown) had underlying sinus rhythm (4 with intermittent pacing), 1 subject was continuously paced, and 4 subjects were diagnosed with atrial fibrillation. All subjects had a sustained ventricular and most had an actual cardiac arrest. | 23 (20 subjects with VF) subjects with 46 recordings (lead I and lead II for each subject) | 24-h ECG | 250 Hz |
| Massachusetts Institute of Technology-Beth Israel Hospital normal sinus rhythm database (NSRBD)22 | Subjects (5 male, 13 female) included in this database were found to have had no significant arrhythmias. Ages between 20 and 50 years old. | 18 subjects with 36 recordings (lead I and lead II for each subject) | 24-h ECG | 128 Hz |
| Malignant Ventricular Arrhythmia Database (VFDB)72 | Subjects who experienced episodes of sustained ventricular tachycardia, ventricular flutter, and ventricular fibrillation. No details on subject's sex. | 22 subjects with 22 recordings | 30-min ECG | 250 Hz |
| Creighton University ventricular tachyarrhythmia database (CUDB)22,73 | Subjects who experienced episodes of sustained ventricular tachycardia, ventricular flutter, and ventricular fibrillation, 5 records were from paced subjects. No details on subject's sex. | 35 subjects with 35 recordings | 8-min ECG | 250 Hz |
| AHA Database for Evaluation of Ventricular Arrhythmia Detectors (AHADB)22 | Subjects with no ventricular ectopy, isolated unifocal PVCs, isolated multifocal PVCs, ventricular bi- and trigemini, R-on-T PVCs, ventricular couplets, ventricular tachycardia, ventricular flutter/fibrillation. No details on subject's sex. | 80 subjects with 80 two-lead recordings | 3-h ECG (2-channel) | 250 Hz |
| Paroxysmal atrial fibrillation prediction challenge database (PAFDB)74 | Subjects who have paroxysmal atrial fibrillation and subjects with no documented AF. No details on subject's sex. | 48 subjects with 50 recordings | 30-min ECG | 128 Hz |
| Spontaneous Ventricular Tachyarrhythmia Database (MVTDB)22 | Subjects with an ICD who experienced an episode of ventricular tachycardia or ventricular fibrillation. No details on subject's sex. | 78 subjects with 135 pairs of RR intervals | EGMs | 1000 Hz |
| Fantasia22 | Twenty young (21–34 years old) and twenty elderly (68–85 years old) healthy subjects underwent 120 min of continuous supine resting while continuous ECG (20 male, 20 female subjects). | 40 individuals with 40 recordings | 120-min ECG | 250 Hz |
ECG = electrocardiography, EGM = intracardiac electrogram, PVC = premature ventricular complex, SCD = sudden cardiac death, VF = ventricular fibrillation.
