1. GENERAL DESCRIPTION
REPLY DR is a DDDR-type dual-chamber rate-responsive
pacemaker.
It is equipped with a physiological sensor (minute ventilation) and an
accelerometer to allow adaptation of pacing to suit the patient's
activity.
REPLY DR provides a range of highly effective therapeutic functions:
Prevention of atrial arrhythmias
Protection of ventricles against atrial arrhythmias (Fallback Mode
Switching)
Preservation of atrioventricular conduction (SafeR mode and
Dplus mode)
Preservation of circadian cardiac rhythm (Rest rate)
Prevention of vasovagal syncope (acceleration)
Automatic adjustment of amplitude of ventricular pacing (Auto-
threshold)
Automatic adjustment of atrial and ventricular sensitivity
(Autosensing)
Protection against Pacemaker-Mediated Tachycardia (Anti-PMT)
2. INDICATIONS
Pacing indications are provided by the American College of
Cardiology and the American Heart Association (see "ACC/AHA/HRS
2008 Guidelines for Device-Based Therapy of Cardiac Rhythm
Abnormalities", J Am Coll Cardiol 2008 May 27;51(21):e1-62).
