Embodiment Construction

[0070] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0071] The heart and autonomic nervous function assessment method based on the NLARI heart rate model provided by the embodiment of the present invention is:

[0072] Heart rate variability is modeled by a nonlinear autoregressive integration model describing a stochastic elastic system, and the heart and autonomic nerve-related functions are quantified through model parameters, and heart rate characteristic indicators and evaluation reference ranges are derived.

[0073] Further, the nonlinear autoregressive integration model of the stochastic elastic system is based on the noise-driven steady-state

[0074] and a stimulu...

Abstract

The invention discloses an NLARI heart rate module-based heart and an autonomic nerve function assessment method. Heart rate variation is modeled via a non-linearity autoregression integration model describing a random elastic system; and heart rate feature indexes and assessment reference range can be derived via parameter-quantization of relative functions of the heart and the autonomic nerve via the model. An assessment system formed by the heart rate feature indexes can be derived in internal-external environment of a cardiovascular system; cardiovascular system and autonomic nerve function assessment can be provided including myocardial metabolism and function, autonomic nerve system and humoral balancing adjusting functions, metabolism level and changes; and cardiogenic stroke death risk indexes can be also improved. Approximate algorithm or chip elements for frequency-domain analysis can be unnecessary, so the method is convenient and high-efficient; and the method integrates biological signal analysis technology and communication network technology, so the whole people health industry development can be promoted.

Description

technical field [0001] The invention belongs to the application field of physiological signal analysis technology in population health, and in particular relates to a heart and autonomic nerve function evaluation method based on an NLARI heart rate model. Background technique [0002] The strength of the cardiovascular system is an important symbol of human health, and an important indicator of human body function assessment and physical fitness evaluation. Using heart rate to evaluate the health of the heart and autonomic nervous system is very important for the effective prevention of cardiovascular diseases, the maintenance of human health and sports health care. has great significance. Studies have shown that reduced heart rate variability (HRV) may be an independent risk factor for death in heart disease patients. Sudden death is a worldwide health problem. In the United States alone, about 1,200 people die of sudden death every day, most of which are sudden cardiac de...
