a. The programmed Normal Brady values will be used as the nominal values for Temporary B rady pacing.
b. Refer to the NASPE/BPEG codes below for an explanation of the programmable values. The identification code of the North
American Society of Pacing and Electrophysiology (NASPE) and the British Pacing and Electrophysiology Group (BPEG) is based
on the categories listed in the table.
c. The basic pulse period is equal to the pacing rate and the pulse interval (no hysteresis). Runaway protection circuitry inhibits
bradycardia pacing above 205 ppm. Magnet application does not affect pacing rate (test pulse interval).
d. Separately programmable for ATP/Post-Shock, Temporary Brady, and EP Test.
e. The minimum value of energy delivered at 5 V and 0.5 ms is 20 µJ with 200–500 Ω, and 12 µJ with 1000 Ω resistive load
at 37°C ± 1°C for BOL and Explant.
f. Values are not affected by temperature variation within the range 20°–43°C.
g. This parameter is used globally in Normal Brady pacing and Post-shock Brady pacing. Changing the value for Normal Brady will
change the value for Post-shock Brady.
h. This parameter is automatically set to at least 85 ms for Post-Shock Brady.
i. This parameter is automatically adjusted in Post-Shock Brady to allow appropriate sensing.
j. This parameter is disabled during Temporary Brady.
k. The programmable values for VR devices only include VVI(R), Off; Temporary: VVI, VOO, Off
l. The programmable values for VR devices only includes VOO and Inhibit Pacing and as such the nominal is VOO.
