System and device for multi-scale analysis and representation of physiological data
First Claim
1. A method for analysis of physiological or health data in at least two levels of detail, said method comprising:
- analyzing a plurality of primary elements in said data in first scale, low level resolution to detect one-time changes in such primary elements and thereby identify abnormal or unstable primary elements;
comparing said primary elements with reference values for such primary elements, and representing deviation of primary elements from the reference values in a form understandable to a lay person;
analyzing at least some of the same said primary elements in said data in second scale, higher level resolution using mathematical decomposition to provide detailed characterization of serial changes in said abnormal or unstable primary elements; and
exchanging information between said analyzing in said first and second levels of resolution to improve at least one of said first and second analyses.

Abstract
System comprised of a medical device and method for analyzing physiological and health data and representing the most significant parameters at different levels of detail which are understandable to a lay person and a medical professional. Low, intermediate and high-resolution scales can exchange information between each other for improving the analyses; the scales can be defined according to the corresponding software and hardware resources. A low-resolution Scale I represents a small number of primary elements such as intervals between the heart beats, duration of electrocardiographic PQ, QRS, and QT-intervals, amplitudes of P-, Q-, R-, S-, and T-waves. This real-time analysis is implemented in a portable device that requires minimum computational resources. The set of primary elements and their search criteria can be adjusted using intermediate or high-resolution levels. At the intermediate-resolution Scale II, serial changes in each of the said elements can be determined using a mathematical decomposition into series of basis functions and their coefficients. This scale can be implemented using a specialized processor or a computer organizer. At the high-resolution Scale III, combined serial changes in all primary elements can be determined to provide complete information about the dynamics of the signal. This scale can be implemented using a powerful processor, a network of computers or the Internet. The system can be used for personal or group self-evaluation, emergency or routine ECG analysis, or continuous event, stress-test or bed-side monitoring.
