Number S1 - This parameter defines the number of stimuli for an
ATP. For Burst + PES, a single extra stimulus with a separate
parameter setting is coupled.
Add S1 - This feature can be programmed with any Burst, Ramp,
or Burst + PES scheme. When “Add S1” is “ON,” the number of
S1 intervals is incremented by one on each successive ATP
therapy. The next S1-S1 interval is dependent on the initial start
interval (S1 decrement) and the programmed Scan Decrement (if
activated).
R-S1 Interval - The R-S1 programmable coupling interval occurs
at the beginning of each ATP. It defines the interval between the
last R-wave signal and the first stimulus (S1). The second
stimulus always follows the first one with the same interval.
S1 Decrement - The S1 decrement continuously reduces the
pulse intervals of the ATP from the second pulse onward.
S1-S2 Interval - The S1-S2 programmable coupling interval
occurs between the Burst sequence and the extra stimuli (PES). It
defines the interval between the first stimulus (S1) and the extra
stimuli (S2).
Scan Decrement - The Scan decrement continuously reduces
the starting pulse intervals of each Burst or Scan.
Minimum ATP Interval - The programmed minimum interval
prevents ATPs from being given with stimulation values less than
the minimum interval. When the ATP interval reaches the value of
the minimum interval with the S1 decrement or scan decrement, it
then assumes this value and remains constant.
2.8.2.1 ATP Help
ATP help is a useful tool to assist the physician in choosing and
confirming appropriate ATP programming. The “ATP Help” button
is displayed in each ATP therapy option. When the ATP help
button is pressed, a histogram of the chosen therapy scheme is
shown. The histogram displays the intervals for the programmed
ATP scheme. When rate adaptive intervals are programmed, the
displayed intervals are based on the programmed R-R average.
