Embodiment Construction

[0023]Fig. 2 is the heart rate variability analyzing device 20 of the present invention, and it mainly comprises a signal amplifier 21, an analog-to-digital converter 22, a computer 23, a digital input / output element 24, an electrocardiogram signal detector 25, a " Execute" button 26 and a casing 32. The casing 32 can be a rectangular three-dimensional structure whose length, width and height are respectively 11, 14 and 4.5 centimeters, and is used to accommodate the signal amplifier 21, the analog-to-digital converter 22, the computer 23 and the digital input / output element 24 and other major devices. The electrocardiogram detector 25 can be made up of three detection electrodes 251, one end of which is connected to the subject, and the other end passes through the casing 32 and is connected to the signal amplifier 21 for picking up the subject's electrocardiogram , and transmit it to the signal amplifier 21. After the electrocardiographic signal is amplified by the signal ...

Abstract

A method for analyzing the variability of cardiac rhythm includes such steps as picking up the cardioelectric signals of a person to be tested, A / D conversion, choosing wave peaks calculating the difference between the amplitude or duration ofw avepeak and reference, rejecting the wave peak signals whose difference is greater than a standard valve, sampling the qualified wave peaks, interpolating to become a series of wave peak signals, and spectral analysis. Its equipment is composed of a cardioelectric signal detector, an amplifier, an A / D converter, a computer and an I / O device connected to an 'execute' key.

Description

technical field [0001] The present invention relates to a heart rate variability analysis method and device, in particular to a programmable heart rate variability analysis method and device, so as to be used by various users. Background technique [0002] The sympathetic and parasympathetic nervous systems belong to the autonomic nervous system and are closely related to the daily operation of the human body. If the autonomic nervous system is out of balance, it may cause a variety of acute or chronic diseases, such as heart disease and high blood pressure, and even sudden death and other emergencies in severe cases. Even in generally healthy people, autonomic abnormalities are often accompanied by heart palpitations, dyspnea, gastrointestinal disturbances, and insomnia. Therefore, the health care of the autonomic nervous system is not only an important topic in the medical profession, but also a personal problem that everyone must face every day. The quality of autonomic...
