    • Overview

    A high percentage of BiV pacing is associated with improved cardiac resynchronization therapy (CRT) response.1 However, the presence of a pacing stimulus does not imply full capture.2,3 Traditional pacing counters only report the presence of a pacing stimulus, potentially leading to over-reporting of effective pacing.2,3

    You can now verify effective pacing with the EffectivCRT™ diagnostic.

    The EffectivCRT™ diagnostic uses a unipolar electrogram to evaluate morphology, looking for a negative deflection which implies when a paced beat is effective.4

    • This EGM strip shows six consecutive paced beats.
    • Traditional pacing counters would report this as 100% V pacing.
    • With the EffectivCRT™ diagnostic, it would report 100% V pacing, but 50% is effective pacing.
      • The first three beats are ineffective (positive deflection implies tissue is paced and not captured).
      • The last three beats are effective (negative deflection implies tissue is paced and captured).

    In 18% of patients, device-reported % V pacing overestimated effective CRT by 3%. Three out of 57 patients had virtually no effective pacing, whereas the % V pacing was > 90%, as demonstrated in the graph below.5

    Before the EffectivCRT™ diagnostic:
    Only see the quantity of pacing5

    With the EffectivCRT™ diagnostic:
    Also see the quality of pacing5

    You can use the data provided by the EffectivCRT™ diagnostic to identify ineffective pacing and will find it in these places:

    • Cardiac Compass™ trends
    • Quick Look™ II screen
    • Rate histogram report
    • EffectivCRT™ episodes
