Visia AF and Visia AF MRI
Implantable Cardioverter Defibrillators (ICDs) for Tachyarrhythmia Management
Single Chamber ICD + AF Diagnostics
Using the TruAF™ Detection Algorithm, Visia AF MRI™ and Visia AF™ are the only single chamber ICDs that can detect atrial fibrillation (AF) with a traditional lead. Ensure your patients get 1.5T and 3T MRI access with Visia AF MRI, when MR conditions for use are met.
The Need for AF Diagnostics in Single Chamber ICDs
- AF increases the risk of stroke by up to 5x1
- AF increases the risk of heart failure by 3x2
- 79-94% of AF episodes are asymptomatic3-8
- 68% of AT/AF episodes are missed with annual Holter monitoring8
- 27% of single chamber ICD patients may also develop new onset AF within the first 6 months post- implant9
TruAF Detection Algorithm
Atrial Fibrillation can conduct into the ventricle resulting in a variable heart rate, which can lead to variability in the timing of the R waves. The TruAF Detection Algorithm monitors R-R variability and looks for patterns, then determines if the variability and pattern are sufficient to meet the classification of AF.
