Selecting Output Parameters
Generally, a pacing voltage twice the chronic stimulation threshold voltage
for a given Pulse Width provides an adequate safety margin. For most
patients, pacing outputs are the major contributor to battery depletion. To
maximize battery longevity, select the lowest amplitudes and pulse widths
that provide at least a 2:1 voltage safety margin. When amplitudes greater
than 2.5 V are required during the maturation phase of the lead(s),
threshold(s) and output setting(s) should be carefully re-evaluated at the
first follow-up.
NOTES
Amplitudes of 5.0 V and 7.5 V substantially reduce expected battery
longevity. These amplitudes should be limited to short term uses such as
“Emergency” settings and electrophysiologic studies or long term uses for
specific indications such as exit block.
High output pacing at 7.5 V may affect ECG or electrogram (EGM)
waveform quality and potentially cause crosstalk or self-inhibition (see
“General Warnings and Precautions,” Section F in Part III).
“Longevity Projections,” Section C in Part III, shows longevity for all
Prodigy models under various pacing scenarios.
For Further Information
Refer to the “Modes and Parameters,” Section E in Part III, for Amplitude
and Pulse Width parameter settings.
