Embodiment Construction

[0034] specific implementation

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] The high-frequency wave of ventricular repolarization is a high-frequency microvolt-level cardiac electrophysiological signal that occurs during ventricular repolarization (S-T-U segment) newly discovered by the applicant. figure 1 It is a typical high-frequency wave of ventricular repolarization. figure 1 In the middle, the upper part is the reference ECG, and the lower part is the high-frequency wave of ventricular repolarization.

[0037] Use dual electrodes from both wrists of the human body (such as figure 2 As shown) to detect the ventricular repolarization high-frequency wave signal, obtain the original signal containing the ventricular repolarization high-frequency wave signal and interference signal through the electrodes on the wrists or arms of both hands, after amplification and analog-to-digital conversion, the in...

Abstract

The invention discloses a ventricular repolarization high-frequency wave double-limb electrode detecting device. An interface circuit is adopted to suppress influence of common mode current; a band-pass filter is adopted to remove noise of instruments; small-wave-range Wiener filtering is adopted, electromyographical interference is removed effectively, and finally extraction of ventricular repolarization high-frequency waves is realized; and the device can obtain original signals containing the ventricular repolarization high-frequency waves and interference signals from two wrists of a patient, after being amplified and realizing digital to analog conversion, the original signals are stored into a memory card via a micro-controller, then data in the memory card are read into a computer, and then ventricular repolarization high-frequency wave signals can be obtained via after the data are processed via software. The ventricular repolarization high-frequency wave double-limb electrode detecting device has the advantages of portability and low power consumption, and can realize long-term dynamic detection.

Description

technical field [0001] The invention relates to the technical field of a ventricular repolarization high-frequency wave detection instrument, in particular to a double-limb electrode detection device for a ventricular repolarization high-frequency wave. Background technique [0002] Sudden death refers to sudden, rapid and unexpected natural death, which accounts for 15% to 32% of human deaths. The definition of sudden death time has not yet been unified. my country adopts the regulations of the World Health Organization (WHO), that is, 1 hour, which is also the time limit accepted by most countries. Sudden Cardiac Death (Sudden Cardiac Death) usually refers to sudden death caused unexpectedly by cardiac causes. According to the latest research report of the American Heart Association, the American College of Cardiology and the American Heart Rhythm Association, according to the tenth revision of the International Classification of Diseases: Sudden cardiac death refers to s...
