Systems and methods are described for adjusting the operation of
implantable stimulation devices used to provide medical monitoring and
treatment. Several hierarchical algorithms are described which operate
according to conditionally obtaining a patient response to an alert
signal. In one such strategy semi-automatic therapy adjustment occurs by
automatically issuing patient alert messages when selected operations are
to occur, and using a patient's response to the alert message that is
provided within a selected time limit in order to contingently adjust
therapy. Methods are also described for resolving conflicts which may
occur when time information and sensed data information each indicate
different patient states are occurring. Although treatment of neural and
cardiac disorders is emphasized, the techniques can be applied to the
monitoring and treatment of any medical disorder with an implanted
device.
