Volume I is in use by over 90% of implantable cardiac device manufacturers and researchers worldwide, including the US Food and Drug Administration.   This volume is the reference standard for implantable device testing. It contains a wide variety of arrhythmia, including ventricular tachycardia, ventricular fibrillation, atrial fibrillation, and others. 

Volume IIis a follow-up to Volume I, and is available only to those who have licensed Volume I.  Again, a wide variety of arrhythmia is represented, both Ventricular and Atrial.

Volume IV is the first of our pure atrial fibrillation volumes, and contains passages of extremely long duration.  This database is necessary for the testing of the new generation atrial fibrillation management devices, such as pacemakers and implantable drug-pumps.

Volume V is the second of our pure atrial fibrillation volumes, and contains passages of extremely long duration.  This database is necessary for the testing of the new generation atrial fibrillation management devices, such as pacemakers and implantable drug-pumps.
