Noninvasive cardiac displacement monitoring system and method

Abstract

The invention relates to the technical field of biomedical engineering and information processing, in particular to a non-invasive cardiac discharge volume monitoring system and method. The monitoring system comprises an upper industrial personal computer and a lower embedded system; the lower embedded system comprises an electrocardiosignal detection module, a thoracic impedance detection module and an acceleration detection module; collected electrocardiosignals, thoracic impedance signals and motion state signals are sent to an upper industrial personal computer through a lower embedded system, the upper industrial personal computer sequentially conducts band-pass filtering, detrending and standardization processing on the electrocardiosignals and the thoracic impedance signals, and after ensemble empirical mode decomposition and canonical correlation analysis processing, important feature points of signal waveforms are obtained in combination with an algorithm, and hemodynamic parameters are calculated in combination with the established biological model; according to the invention, high-frequency and low-amplitude current of a human body is injected into hardware, so that measurement signals are prevented from being interfered by low-frequency noise from other electronic or physiological emitters; the defect that a traditional ICG model depends on human body-based impedance Z0 is overcome.

Description

Technical field [0001] The present invention relates to the field of biomedical engineering techniques and information processing, and in particular, there is a non-invasive cardiac monitoring system and method. Background [0002] Based on the cardiac discharge monitoring system of bioelectric impedance technology, it has a huge application value for cardiac severe rehabilitation. Its blood dynamics data reflects the indicators of cardiac pump blood, human organs and tissue oxygen metabolism, peripheral circulation resistance, etc., its clinical value is increasing Significantly, provide intuitive reference data for the diagnosis and treatment of cardiovascular clinical patients. Traditional creative blood flow monitoring technology such as Swan-Ganz and Picco although it is a gold standard, but its high price, there is a risk, time-consuming long, need special equipment and technical training, etc., many hospitals are difficult to buy the equipment, and they cannot Conduct the ...

AI Technical Summary

Problems solved by technology

At present, domestic static heart function product technology has begun to show, but cardiac function testing equipment such as exercise cardiac function tester and exercise ECG rely on imports, and the detection equipment is relatively expensive and difficult to operate. Places are difficult to be widely promoted, seriously restricting the development of cardiac rehabilitation services
