The AF Suppression algorithm continually monitors intrinsic atrial rate, increasing the stimulation rate when the intrinsic rate increases, thereby providing atrial pacing at a rate just above the intrinsic sinus rate. It is designed to overdrive the intrinsic atrial rate to prevent the emergence of atrial tachyarrhythmias without unnecessary, continuous high-rate atrial stimulation. Unlike fixed overdrive systems, AF Suppression technology ensures that the stimulation rate is appropriate for patient activity (i.e., not unnecessarily high when the patient is at rest, yet sufficiently rapid when the patient is active).
The AF Suppression algorithm is the only clinically proven algorithm to suppress episodes of paroxysmal and persistent AF. Studies show a 25% decrease in symptomatic AF burden.1
