Method and apparatus for assessing autonomic function
First Claim
1. A method for assessing autonomic function comprising the steps of:
- obtaining first physiologic data of a patient wherein the first physiologic data is derived from one or more non-provocative studies;
obtaining second physiologic data of the patient wherein the second physiological data is derived from one or more provocative studies; and
utilizing the first and second physiological data in an assessment tool for assessing the patient'"'"'s autonomic function.

Abstract
The invention analyzes relationships between factors, within a patient population, to identify autonomic dysfunction patterns. Patient test results are then compared with the identified patterns to determine the patient'"'"'s autonomic function. The invention can continually amend the patient population with new test results to create increasingly accurate normative data sets from which a patient'"'"'s autonomic function can be more accurately assessed. The invention may apply this concept in an application service provider model. An embodiment of the invention may use a novel method of identifying ECG R-waves. The method locates R-waves by searching for maximum slope values, in signals, that exceed threshold values. Another embodiment of the invention entails utilizing data from a non-provocative HRV test and a provocative HRV test in an assessment tool to assess a patient'"'"'s autonomic function.

16. A system for assessing autonomic performance comprising:
-
one or more memory units operable for storing one or more computer products for assessing autonomic performance; and
one or more processors coupled to the one or more memory units, wherein the one or more processors execute the one or more computer products for performing the steps of;
obtaining first physiologic data of a patient wherein the first physiologic data is derived from one or more non-provocative studies;
obtaining second physiologic data of the patient wherein the second physiological data is derived from one or more provocative studies; and
utilizing the first and second physiological data in an assessment tool for assessing the patient'"'"'s autonomic function. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 47)

28. A method for assessing autonomic function comprising:
-
obtaining first physiologic data of a patient wherein the first physiologic data is derived from one or more non-provocative studies;
deriving first HRV data from the first physiologic data;
obtaining second physiologic data of the patient wherein the second physiological data is derived from one or more provocative studies;
deriving second HRV data from the second physiologic data; and
inputting the first and second HRV data into a discriminant equation to provide an autonomic ranking that is indicative of an autonomic function of the patient;
wherein the discriminant equation discriminates between a first group of patients with a first state of autonomic function and a second group of patients with a second state of autonomic function. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)

obtaining first physiologic data of a patient wherein the first physiologic data is derived from one or more non-provocative studies;
obtaining second physiologic data of the patient wherein the second physiological data is derived from one or more provocative studies;
inputting the first and second physiologic data into a discriminant equation which discriminates between a first group of patients with a first state of autonomic function and a second group of patients with a second state of autonomic function; and
generating an autonomic ranking that is indicative of an autonomic function of the patient from the first and second physiologic data input into the discriminant equation. - View Dependent Claims (37, 38, 39, 40)

first data, second data, combinations thereof and derivations thereof;
wherein the first data is derived from one or more non-provocative studies; and
wherein the second data is derived from one or more provocative studies; and
