ECG analysis algorithm
Databases used for the VF/VT recognition algorithm tests:
• MIT-BIH Arrhythmia Database.
• MIT-BIH Atrial Fibrillation Database.
• MIT-BIH Supraventricular Arrhythmia Database.
• European Society of Cardiology.
• Creighton University.
Test report:
•
Recording methods:
the files were acquired via internet through the MIT-BIH
database and used via computer.
•
ECG rhythm sources:
MIT-BIH, on http://ecg.mit.edu/
•
Rhythm selection criteria:
rhythms were chosen according to notes present in
the MIT-BIH database.
•
Criteria and annotation methods:
the rhythms were recognized and annotated
in a separate file. Later they were recognized and compared for sensitivity and
specificity calculations.
