Nondestructive detection system and method of cardiac function

Abstract

The invention provides a nondestructive detection system and a nondestructive detection method of a cardiac function. The nondestructive detection system of the cardiac function mainly comprises a central control computer, and an electrocardiography signal acquisition module, a heart sound signal acquisition module and a thoracic impedance acquisition module which are in data communication with the central control computer to acquire an electrocardiography signal, a heart sound signal and a thoracic impedance signal respectively, wherein related physiological and pathological characteristic parameters are obtained from the electrocardiography signal, the heart sound signal and the thoracic impedance signal through comprehensive processing of the central control computer, and further related index parameters of the cardiac function are obtained and displayed in real time. The nondestructive detection system and the nondestructive detection method of the cardiac function have higher detection accuracy; the clinical applicability of the nondestructive detection system and the nondestructive detection method is improved; the technical blank that effective nondestructive detection related equipment of the cardiac function is not available yet at present in China; rich operation and remote functions can be realized by combining the conventional computer technology and network technology, and the nondestructive detection system and the nondestructive detection method have excellent application prospect.

Description

technical field [0001] The invention relates to the fields of biomedical engineering technology and information processing technology, in particular to a system and method for non-invasive detection of cardiac function. Background technique [0002] The monitoring of hemodynamic parameters reflecting cardiac power has been used clinically for many years. The monitoring of hemodynamic parameters can provide a lot of valuable parameter information, such as cardiac pump function index parameters, cardiac systolic function index parameters, cardiovascular function index parameters, etc. These heart function-related index parameters are important for medical and scientific research. have important clinical significance. With the development of clinical medicine, various hemodynamic detection methods have emerged as the times require. At present, the methods of hemodynamic testing are mainly divided into two categories: the first category is invasive testing methods, that is, tr...
