Reactive ATP Algorithm Cardiac Device Features

Overview

Atrial Fibrillation (AF) can spontaneously organize to slower and/or more organized atrial rhythms. The Reactive ATP^™ (rATP) algorithm delivers atrial antitachycardia pacing (ATP) to terminate an ongoing atrial fibrillation (AF) episode after a programmed interval or when the rhythm organizes and/or slows.

REACTIVE ATP reduces progression of AF
ACROSS PACEMAKERS, ICDS, AND CRT DEVICES²

• An analysis of 8,032 patients in the Medtronic CareLink™ database assessed the impact of rATP across pacemakers, ICDs, and CRT devices.
• Key finding: rATP was associated with a reduction in the progression of AF (≥ 1 day, ≥ 7 days, and ≥ 30 days) across all device types (p < 0.001).
• This retrospective analysis is the first to demonstrate rATP’s benefit across device types, and in areal-world setting.

Model components included group, age, sex, baseline AF, and device type. Frailty model results were consistent with those from Cox proportional hazard models (P< 0.0001 for all).

Turning on REACTIVE ATP

Follow these steps to turn Reactive ATP on in pacemaker, implantable cardioverter defibrillator (ICD), and cardiac resynchronization therapy (CRT) devices after lead maturation.

• AT/AF detection is nominally set to Monitor to ensure the atrial lead has matured (approximately one month after implant) before the therapy is enabled.
• Review the Clinician Manual for information on treating AT/AF episodes with ATP therapies and detailed instructions on the programming options for scheduling atrial therapy.
