WARNING!
There are three pacing modes available: S00, SSI, SST
as well as high-frequency pacing (Burst).
For disturbances caused by electromagnetic interference
(EMI), after certain limits are exceeded
Reocor S will switch to operating mode S00 for the
duration of the disturbance.
The pacemaker sends pulses with a constant rate. The
pulses are asynchronous, i.e. not synchronized with
the intrinsic heartbeats.
This mode functions when connected to the ventricle
as V00 and to the atrium as A00.
The pacemaker inhibits pulses when intracardiac
potentials are sensed. It sends pulses if no event is
sensed within one of the intervals corresponding to
the selected frequency.
This mode functions when connected to the ventricle
as VVI and when connected to the atrium as AAI.
The triggered pacing mode SST corresponds to the
pacing modes SSI with the following distinction: no
pulse inhibition takes place upon sensing of an event
outside of the refractory period, instead pulse delivery
is carried out immediately in the respective chamber.
The rate of the burst function can be selected with the
control dial (10) from 60 ppm to 1000 ppm.
This function is activated with two key buttons: First
the Select burst key button (11) must be pressed and
then, within two seconds, the Start burst key button
(8) must be pressed. The pulse delivery then lasts as
long as the Start burst key button is pressed.
After a burst stimulation in the atrium, the ventricular
blanking interval can prevent sensing of intrinsic signals
and lead to asynchronous pacing in the ventricle.
