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 Arrhythmia Database.

Test report:
•
Recording Methods: t
he files were acquired via internet through the MIT-BIH
database and used via computer.
