Pacing Modes and Parameters

Cross Channel Blanking

After a stimulus has been delivered, sensing is sup-
pressed for 110 ms in the opposite channel to prevent
far-field sensing.

Interference interval

The interference interval is started by both atrial and
ventricular paced and sensed events.
The interval is reset by noise sensed in any channel
during the interval length of 80 ms, leading to asyn-
chronous pacing at the programmed rate while the
interference lasts.
For instance, in the operation mode DDD, an atrial
interference that does not affect the ventricular
channel leads to DVI pacing. Sensing of noise in the
ventricular channel leads to DAD pacing.
Interference in both channels results in D00 pacing.

Burst

The rate of the Burst rate atrium function can be
selected with the control dial (14) between 60 ppm and
1000 ppm.
This function is activated with two key buttons: First
the Select burst key button (16) must be pressed and
then, within two seconds, the Start burst key button
(12). The pulse delivery then lasts as long as the Start
burst key button is pressed. During this activation, the
ventricular channel will continue to pace at the pro-
grammed rate, (which can be adjusted during this
process). If an inhibiting operating mode has been
programmed, pacing will be inhibited in the ventricle.
WARNING! After a burst stimulation in the atrium, the ventricular
blanking interval can prevent sensing of intrinsic sig-
nals and lead to asynchronous pacing in the ventricle.
