Virtuoso™ ICDs

Virtuoso Dual Chamber ICD: [DR ICD]1
with Atrial Therapies and Diagnostics

  • 35 Joules, delivered
  • 8.2 seconds BOS*, 9.8 seconds RRT**
  • Longevity 6.9 years2
  • 37 cc, 68g
  • Size: H x W x Da - 64 x 51 x 15mm
  • Enhanced PR Logic® Dual Chamber Detection maintains high sensitivity for ventricular tachyarrhythmias while improving discrimination for supraventricular tachycardias. Offers 95.2% accuracy Positive Predictive Value (PPV) in delivered therapies.3
  • Enhanced PR Logic Dual Chamber Detection with modified Sinus Tach Rule rejects over one-third more SVTs compared to the original PR Logic with no user programming.***4
  • Programmable with the Medtronic CareLink® programmer.

Virtuoso Single Chamber ICD: [VR ICD]1

  • 35 Joules, delivered
  • 8.2 seconds BOS*, 10 seconds RRT**
  • Longevity 8.0 years5
  • 37 cc, 68g
  • Size: H x W x Da - 64 x 51 x 15mm
  • Wavelet Dynamic Discrimination Criterion is an electrogram morphology algorithm with simple on-off programming.
  • In the WAVE study, Wavelet Discrimination Criterion reduced inappropriate therapy by 78.2% based on 100% spontaneous arrhythmias.****6
  • Programmable with the Medtronic CareLink® programmer.
