USE OF CARDIAC PARAMETERS IN METHODS AND SYSTEMS FOR TREATING A CHRONIC MEDICAL CONDITION
First Claim
1. A method of treating a chronic medical condition in a patient, comprising:
- determining a time of beat sequence of the patient'"'"'s heart;
determining a regulatory system parameter based on said time of beat sequence, wherein said parameter is indicative of a stress level of the patient'"'"'s regulatory adaptation systems;
comparing said determined regulatory system parameter with a threshold regulatory system parameter value; and
applying an electrical signal to a neural structure of the patient to treat the chronic medical condition if said determined regulatory system parameter exceeds said threshold regulatory system parameter value.

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.

7. A method of treating a chronic medical condition in a patient, comprising:
-
determining a time of beat sequence of the patient'"'"'s heart; determining a heart rate variability (HRV) parameter based on said time of beat sequence, wherein said HRV parameter is associated with a parasympathetic function of the patient; comparing said determined HRV parameter with a threshold HRV parameter value; and applying an electrical signal to a neural structure to treat the chronic medical condition if said determined HRV parameter exceeds said threshold HRV value. - View Dependent Claims (8, 9)

10. A medical device for treating a chronic medical condition in a patient, comprising:
-
a sensing module for sensing data relating to a time of beat sequence of the patient'"'"'s heart; a heart beat data processing module to process the data relating to the time of beat sequence; a heart parameter module adapted to determine at least one heart parameter selected from a heart rate variability (HRV) parameter associated with a parasympathetic function of the patient and a regulatory system parameter indicative of a stress level of the patient'"'"'s regulatory adaptation systems, wherein said heart parameter module is also adapted to determine said at least one heart parameter based upon the processed data relating to the time of beat sequence of the patient'"'"'s heart; a comparator adapted to compare the at least one heart parameter determined by said heart parameter module with a threshold heart parameter value; and an electrical signal module adapted to generate and apply an electrical signal to a neural structure to treat the chronic medical condition in the patient based upon the comparison of the determined heart parameter value and the threshold heart parameter value. - View Dependent Claims (11, 12, 13, 14, 15)

16. A computer readable program storage device encoded with instructions that, when executed by a computer, performs a method of providing a therapy to a patient having a chronic medical condition, the method comprising:
-
determining a time of beat sequence of the patient'"'"'s heart; determining a first index of regulatory activity systems (IARS) value associated with the patient based upon the time of beat sequence; comparing the first IARS value to a first threshold IARS value; and providing a therapy to the patient in response to a determination that the first IARS value exceeds the first threshold IARS value. - View Dependent Claims (17, 18, 19, 20, 21)

22. A computer readable program storage device encoded with instructions that, when executed by a computer, performs a method of providing a therapy to a patient having a chronic medical condition, the method comprising:
-
determining a time of beat sequence of the patient'"'"'s heart; determining an HRV parameter indicative of parasympathetic activity from said time of beat sequence; comparing the determined HRV value to a threshold HRV value; and providing a therapy to the patient in response to a determination that the HRV value is below the threshold HRV value.

-
a sensing module for sensing data relating to a time of beat sequence of the patient'"'"'s heart; a heart beat data processing module adapted to process the data relating to the time of beat sequence; a regulatory activity module adapted to determine an index of regulatory activity systems (IARS) value associated with the patient based upon the data relating to the time of beat sequence of the patient'"'"'s heart, wherein the IARS value is indicative of level of stress upon the regulatory system of the patient; and a communication module adapted to provide the IARS value to at least one of a patient or a healthcare provider; and wherein the medical device is adapted to provide a treatment to the patient in response to a determination that the IARS value indicates a chronic condition in the patient. - View Dependent Claims (24, 25, 26, 27, 28)
