Apparatus and method of processing a subject-specific value based on beat-to-beat information
First Claim
1. An apparatus comprising:
- a memory anda processor to process a subject-specific value of a parameter corresponding to a subject based on input beat-to-beat information corresponding to said subject, the subject-specific value determined based on a quotient of first and second factor values, the first and second factor values determined based on a two-dimensional representation of said beat-to-beat information on a coordinate system including a first axis and a second axis, the first factor value determined based on points within a first axis-interval of said first axis, and the second factor value determined based on points within a second axis-interval of said second axis,wherein said subject-specific value is configured to be compared to at least one predefined reference value corresponding to at least one medical condition, and wherein a relationship between the subject-specific value and the reference value is to represent a risk of said subject to suffer from said medical condition.

Abstract
A system for measuring heart rate variability (HRV) comprising 3 sub-systems: a data collection sub-system, a data analysis sub-system, and an output sub-system. A patient is connected to a heart monitoring device such as an ECG and the data collection sub-system records the patients heart beats, and an ECG chart is produced from which the patient'"'"'s HRV value is derived by the data analysis sub-system. The present invention obtains the HRV value through calculation of a new parameter called relative density (RD). In accordance with the inventive method, data points are generated from the peak interval data of measured heart beats and the HRV relative density parameter (RD) is calculated by correlation between two subsets of data points.
