Intrinsic ATP Algorithm

Intrinsic ATP™ is the only automated and smart ventricular antitachycardia pacing (ATP) algorithm that provides individualized therapy in real time.

In a virtual modeling study, Intrinsic ATP’s termination rate was 17 percentage points higher than traditional ATP (burst) with no difference in acceleration rate.7

Streamlined Workflows & Heart Failure Management 

TriageHF Technology

TriageHF™¶ is a simplified, integrated heart failure risk assessment tool that alerts clinicians to clinically relevant changes in a patient’s status that may lead to a heart failure decompensation.

These values should not be interpreted as precise numbers. Individual patient results may vary based on their specific programming and experience.

With AdaptivCRT™ programmed to BiV and LV.

Energy delivered at connector block into a 50 Ω ± 1% load.


Energy stored at charge end on capacitor.


From ADVANCE III, using ATP during charging along with NID = 30/40 programming, ATP reduced shocked episodes by 52%.8

TriageHF is not an alarm. The TriageHF assessment does not replace heart failure assessments in standard clinical practice. Medical treatment should not be modified remotely based solely on the TriageHF assessment. Interpretation of the TriageHF assessment requires clinical judgement by a medical professional. The TriageHF assessment should be used in conjunction with professional guidelines for patient management decisions.


TriageHF requires clinic activation. Contact your local Medtronic sales representative for activation requirements
