Tachycardia Detection Issues
INACCURATE AUTOSTIMS AT FOLLOW-UP VISIT
Sometimes generator detection settings may miss detecting heart rate changes
that may be associated with a seizure. The following conditions may be
potential causes:
Heart rate changes
Exercise, physical activity, and normal
sleep can increase the heart rate and
cause the generator to falsely declare
an event.
Duty cycle
Because the generator can only
detect events during OFF time, the
OFF time aects accuracy. Shorter
OFF time means less chance for the
generator to detect events. Longer
OFF time, on the other hand, means
more chance for the generator to
detect events.
