Therapeutic Improvements; Safer Mode; Dplus Mode - sorin REPLY DR Manual De Implante

Warnings: Use the Rate Response function cautiously in cases of:
1. Severe coronary insufficiency. 2. Severe aortic stenosis. 3. Myocardial
function compromised by undue accelerations of the pacing rate.
Programming at implant: "Learn" and "RR Auto" should not be
programmed prior to implant so as not to distort autocalibration.
Surgical procedure: For safety reasons, it is preferable to
deprogram the Rate Response function before any surgical
procedure on the pacemaker patient.
Programming requirement: 1. The SafeR/DDIR, DDD/DDIR
and Dplus/DDIR modes (Rate response during fallback mode switching)
are accessible only if Fallback mode switching is programmed.
Note: To protect the patient from prolonged pacing at high rates, rate
responsive pacing is deactivated if the patient is paced at a rate higher
than 100 min-1 for a large number of cycles during any 24-hour period.

7.6. THERAPEUTIC IMPROVEMENTS

i SafeR mode
SafeR mode is intended to minimise unnecessary ventricular pacing.
The pacemaker functions in AAI mode, and temporarily switches to
DDD mode upon the occurrence of AVB III, AVB II, AVB I and Pause.
i Dplus mode
Dplus pacing mode preserves spontaneous atrioventricular conduction.
Operation: An AV monitoring period allows small variations in the
spontaneous atrioventricular delay. If no ventricular sensing occurs during
that period, the pacemaker converts to DDD mode until atrioventricular
conductions returns to normal. In DDD mode, the pacemaker uses the
AV delays calculated from the averaged PR intervals.
The Dplus-R mode is a Dplus mode with Rate Response.
