Basic Rate during Mode Switching
It is possible to set a higher basic rate during mode switching, in order
to lessen undesirable hemodynamic conditions during mode switching.
This basic rate can be programmed to a higher value than the standard
basic rate, which leads to a slight increase of the cardiac output.
Programmable parameters:
Basic Rate during
Mode Switching
+5...(5)...+30 ppm
Note: In the CLS modes, the Closed Loop rate is slowly
reduced to the sensor rate during mode switching.
If no rate-adaptive mode has been set for mode
switching, the CLS rate is slowly reduced to the
basic rate for during mode switching.
2:1 Lock-in Management
Description
When high atrial rates occur (such as during atrial flutter) in
conjunction with a relatively large AV delay, every other P wave may
regularly fall in the atrial far-field blanking (FFB) period. In this case,
the implant only detects half of the preceding atrial rate.
