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.
Claims20
A system for measuring heart rate variability (HRV), the system comprising:
- a data generator to receive heartbeat information of a subject, the heartbeat information recorded by a data collector, said heartbeat information representing a series of heart beat intervals corresponding to said subject, said data generator is further to generate a plurality of data points based on the heartbeat information in the form of a two-dimensional representation having a coordinate system including a first axis and a second axis;
- a data analyzer to identify two subsets of data points from said plurality of data points, said two subsets including a first subset of data points within a first axis-interval of said first axis, and a second subset of data points within a second axis-interval of said second axis;
- a processor to calculate a subject-specific heart rate variability (HRV) relative density parameter (RD) value by dividing a first factor, which is based on said first subset of data points by a second factor, which is based on the second subset of data points;
- and
- an output device, to output the subject-specific HRV RD value.
A computer-based method for measuring heart rate variability (HRV), the method comprising:
- receiving, by a computing device, heartbeat information of a subject, the heartbeat information recorded by a data collector, said heartbeat information representing a series of heart beat intervals corresponding to said subject;
- generating, by said computing device, a plurality of data points based on the heartbeat information in the form of a two-dimensional representation having a coordinate system including a first axis and a second axis;
- identifying, by said computing device, two subsets of data points from said plurality of data points, said two subsets including a first subset of data points within a first axis-interval of said first axis, and a second subset of data points within a second axis-interval of said second axis;
- calculating, by said computing device, a subject-specific heart rate variability (HRV) relative density parameter (RD) value by dividing a first factor, which is based on said first subset of data points by a second factor, which is based on the second subset of data points;
- and
- outputting the subject-specific HRV RD value.
