Comprehensive suite of physiologic features available in every Reply DR


Provides AAI pacing while continuously monitoring for AV block.

Ensures DDDR pacing when needed and switches back to AAI when possible.

SafeR is proven to be safe and effective for all patients with bradyarrhythmia.2,3

REPLY (for US) Kora3 1


DPlus, a dual-chamber pacing algorithm with AV search hysteresis, promotes intrinsic conduction without missing a beat.


WARAD (Window of Atrial Rate Acceleration Detection) enables patients to benefit from dual-chamber pacing while preventing inappropriate tracking of atrial tachycardias.


Identifies a sudden drop in cardiac rate for the treatment of vasovagal syndrome and carotid sinus syndrome.

Twin Trace

Twin Trace combines an accelerometer and a minute ventilation sensor to provide rate response closest to sinus rhythm.
