Second-generation atrial-based antitachycardia pacing (rATP) algorithms deliver targeted therapies based on atrial cycle length and regularity to mitigate atrial fibrillation burden.
Second-generation atrial-based antitachycardia pacing algorithms track rhythm transitions to deliver targeted therapies for mitigating atrial fibrillation burden.
Second-generation atrial-based antitachycardia pacing (rATP) represents a therapeutic avenue for mitigating atrial fibrillation (AF) burden in patients equipped with cardiac implantable electrical devices. When the rATP algorithm detects an AF episode, the device tracks rhythm transitions based on regions consisting of atrial cycle length (CL) and regularity. A maximum of 3 antitachycardia pacing therapies (eg, ramp or burst+) with various numbers of sequences can be delivered to each region with a CL in the 50-millisecond range for regular rhythms and 100- to 150-millisecond range for irregular rhythms.
