Intrinsic ATP (iATP) Cardiac Device Features

Intrinsic ATP™ (iATP) is the only automated and smart ventricular antitachycardia pacing (ATP) algorithm that provides individualized therapy in real time. Available on Cobalt™ XT ICDs and CRT-Ds, iATP is the only ATP algorithm that learns and adapts to terminate ventricular tachycardia (VT).

Opportunity to Reduce Shocks with Intrinsic ATP

In a virtual modeling study, Intrinsic ATP’s termination rate was 22% higher than traditional ATP (burst) with no difference in acceleration rate.1
