1. AUTOTAGGING: Allows for the automated tagging of regions of interest on the mapping system (only available with EnSite X).

2. DISPERSION INDICATOR: Multipolar electrogram abnormality associated with the perpetuation of atrial fibrillation. Red: highly dispersed electrograms. Orange: dispersed electrograms. Blue: non-dispersed electrograms

3. MAPPING CATHETER: Steerable, multipolar electrode catheter. Allows for the recording of the heart’s local electrical activity.
4. BOOSTER MODE: May be activated during AT or slow AF to increase software sensitivity.

5. REFERENCE CYCLE LENGTH: Atrial cycle length estimated from real-time recordings obtained with the coronary sinus catheter.

6. MAPPING CYCLE LENGTH: Local cycle length estimated from real-time recordings obtained with the mapping catheter

Legal Mentions and References


The Volta AF-Xplorer™ system is a Medical Device manufactured by Volta Medical. This product is FDA cleared.


CAUTION: Federal (United States) law restricts this device to sale by or on the order of a physician. See Instructions for Use for full prescribing information, including indications, contraindications, warnings, precautions and adverse events. All safety considerations, cautions and warnings that apply to the general use of a medical system in an operating room, also apply while using Volta AF-Xplorer application. There are no known potential adverse events associated with the use of Volta AF-Xplorer.

Indications: The Volta AF-Xplorer assists operators in the real-time manual or automatic annotation of 3D anatomical and electrical maps of human atria for the presence of multipolar intra-cardiac atrial electrograms exhibiting spatiotemporal dispersion during atrial fibrillation or atrial tachycardia.

The clinical significance of utilizing the Volta AF-Xplorer software to help identify areas with intra-cardiac atrial electrograms exhibiting spatiotemporal dispersion for catheter ablation of atrial arrhythmias, such as atrial fibrillation, has not been established by clinical investigations.

Contraindications: The Volta AF-Xplorer has no specific contraindications.
