Avd Paced/Sensed Offset; Rate Response - sorin REPLY DR Manual De Implante

i AVD Paced/Sensed Offset
An AVD Paced/Sensed Offset is a period added to the AV delay after
atrial pacing.
Programming requirement: In Dplus mode, the AV delay plus the AVD
paced/sensed offset between atrial and ventricular pacing cannot exceed
350 ms. In the other pacing modes, the AV delay plus the AVD
paced/sensed offset between atrial and ventricular pacing cannot exceed
300 ms.

7.5. RATE RESPONSE

The Rate Response function makes it possible to adjust the pacing
rate based on the patient's physical activity.
Sensors used: The pacemaker is equipped with two sensors which
prevent rate increases due to artefact through cross-checking of
information.. 1. Minute ventilation (MV): this is calculated based on the
measurement of transthoracic impedance by standard (unipolar
or bipolar) intracardiac leads. It is used to obtain a physiological response
proportional to the degree of exertion during periods in which the patient
is active. 2. An accelerometer (G), which measures changes in the
patient's anteroposterior acceleration: a rapid response may thus be
obtained at the start of exertion and the end of exertion can be detected
immediately.
Examples: 1. Automatic rate response ("RR Auto" option). The pacing
rate is constantly adapted to the patient's physical activity. 2. Manual rate
response ("RR Fixed" option). In that case, manual programming of the
patients physical activity determines the pacing rate applied, based on the
sensor signal. 3. Rate response during fallback mode switching
(SafeR/DDIR, DDD/DDIR and Dplus/DDIR modes). Rate response is
inactive if the patient is in sinus rhythm. It becomes active when atrial
arrhythmia is sensed.
