Use of cardiac parameters in methods and systems for treating a chronic medical condition
First Claim
1. A method of adapting treatment of a patient having a chronic medical condition during periods of heightened stress on regulatory adaptation systems of the patient, comprising:
- applying a first electrical signal to a neural structure of the patient to treat the chronic medical condition, the first electrical signal defined by a first set of signal parameter values;
determining a time of beat sequence of the patient'"'"'s heart;
determining a first index of activity of regulatory systems (IARS) value based on said time of beat sequence, the first IARS value indicative of a stress level of the regulatory adaptation systems of the patient;
comparing the first IARS value to a first IARS threshold; and
adjusting the first electrical signal to provide a second electrical signal to the neural structure of the patient in response to the first IARS value exceeding the first IARS threshold, the second electrical signal defined by a second set of signal parameter values, wherein at least one value of the second set of signal parameter values is different from a corresponding value in the first set of signal parameter values.

Abstract
Disclosed herein are methods, systems, and apparatus for treating a chronic medical condition in a patient. A time of beat sequence of the patient'"'"'s heart is determined. A regulatory system parameter is determined based on the time of beat sequence. The parameter is indicative of a stress level of the patient'"'"'s regulatory adaptation systems. The determined regulatory system parameter is compared with a threshold regulatory system parameter value. An electrical signal is applied to a neural structure of the patient to treat the chronic medical condition if the determined regulatory system parameter exceeds the threshold regulatory system parameter value.
