AdaptivCRT Algorithm Cardiac Device Features

Overview

The AdaptivCRT™ Algorithm Optimizes CRT Pacing Every Minute Whether AV Conduction Is Normal, Prolonged, or Blocked

It adapts to meet the constantly changing needs of CRT patients because it responds to what he or she is doing and automatically decides when and how to pace the heart. 

The AdaptivCRT Algorithm has two different modes:

  • AdaptivCRT LV Only Pacing occurs during normal AV conduction when the heart rate is less than or equal to 100 beats per minute. It also optimizes A-V timing and minimizes right ventricular (RV) pacing.
  • AdaptivCRT BiV Pacing occurs during prolonged/blocked AV conduction or when the heart rate is greater than 100 beats per minute. It also optimizes A-V and V-V timing.
