Overview

The EffectivCRT™ during AF algorithm automatically changes the pacing rate to increase effective CRT delivery during AF by up to 15%.1

Our prospective, randomized, multicenter crossover study demonstrated the ability of the EffectivCRT™ during AF algorithm to increase effective pacing (N = 54).

Results showed:

  • EffectivCRT™ during AF increased effective pacing, from 81% to 88% (p < 0.001).
  • Heart rate increased by three beats per minute, from 77 to 80 bpm (p < 0.001).
  • Patients with baseline (< 80%) paced received the greatest benefit.

How does the EffectivCRT™ during AF algorithm work?

Maintain effective pacing in the presence of AF.

If a paced beat is ineffective (or a sensed event), EffectivCRT™ during capital AF increases the pacing rate.

If a paced beat is effective, EffectivCRT™ during AF decreases the pacing rate.
