Exclusive algorithms to manage AF and optimize CRT delivery​

  • Reactive ATP™ algorithm opportunistically attempts to terminate an AF episode when the rhythm organizes and/or slows.​
  • 36% relative reduction in AT/AF episodes ≥ 7 days with Reactive ATP™ Algorithm∆1​
  • AdaptivCRT™ Algorithm adapts to patients’ changing needs by optimizing CRT pacing minute-to-minute.​
    • 16% mortality in AdaptResponse at 5 years is the lowest of any radomized CRT trial, when accounting for NYHA class.2–9
    • 93% response rate overall at 6 months, highest of any CRT trial1,10–17​
    • High percent Adaptive LV pacing associated with 24% significant reduction in mortality/HF events2​
    • 41% lower rate of device change-outs for battery depletion through 8 years with AdaptivCRT™ algorithm​2

Streamlined heart failure management with CareAlert™ notifications

Time to a clinical decision was about seven times faster with the use of Medtronic CareAlert™ notifications compared to standard office follow-up.7

Clinical management alerts:

  • Atrial tachyarrhythmia / atrial fibrillation (AT/AF) daily burden enable 
  • Average ventricular rate during AT/AF 
  • Monitored ventricular tachyarrhythmia (VT) episode 
  • Ventricular pacing < 90%

Device management alerts: 

  • Low battery voltage recommended replacement time (RRT) 
  • Atrial pacing enable  
  • Right-ventricular (RV) pacing enable   
  • Left-ventricular (LV) pacing enable  
  • Atrial capture enable  
  • RV capture enable  
  • LV capture enable

† Comparing AdaptivCRT™ to echo-optimized BiV pacing in patients with normal AV conduction, percentage of patients improved in Packer clinical composite score (CCS) at 6-month follow-up. CCS is a composite measure of mortality, HF hospitalizations, and symptomatic changes.

‡ Patients who received AdaptivCRT™ were associated with a 29% relative reduction in all-cause mortality versus conventional CRT (after adjusting for other potential risk factors including age, gender, LVEF, NYHA class, QRS duration, AF, CAD, hypertension, AV block, and LBBB).

§ Most of the reduction in AF occurred in subgroups with prolonged AV conduction at baseline and with significant left atrial reverse remodeling.
