EffectivCRT During AF Algorithm Cardiac Device Features

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 3 beats per minute, from 77 to 80 BPM (p < 0.001).
  • Patients with baseline (< 80%) paced received the greatest benefit.
Graphic shows results from study highlighting that EffectivCRT™ During AF increases effective CRT delivery during AF by up to 15%.

HOW DOES THE EFFECTIVCRT DURING AF ALGORITHM WORK?

Image of how EffectivCRT™ During AF works. If a paced beat is ineffective (or a sensed event), EffectivCRT™ During AF increases the pacing rate. If a paced beat is effective, EffectivCRT™ During AF decreases the pacing rate.
