Repetitive Hysteresis

Repetitive hysteresis has been incorporated to promote
spontaneous cardiac rhythm and may reduce pulse generator
energy consumption.

N

OTE

:

 Repetitive and Scan Hysteresis are only available when
Hysteresis is selected on.
 There is one Standard Hysteresis interval which occurs
before the programmable number of Repetitive Hysteresis.

2.9.4.2 Scan 

Hysteresis

Scan hysteresis is expanded programmability of the Hysteresis
feature.  Scan hysteresis searches for an intrinsic cardiac rhythm,
which may exist just below the programmed lower rate (or sensor-
indicated rate).  Following 180 consecutive paced events, the
stimulation rate is temporarily decreased to the hysteresis rate for
a programmed number of beats.  If a cardiac rhythm is not
detected within the programmed number of beats at the
hysteresis rate, the stimulation rate returns back to the original
lower rate (or sensor-indicated rate).  Several programmable beat
intervals are available to allow a greater probability of detecting a
spontaneous rhythm.
