Household cardiac monitoring system based on electrocardio and cardiac sound analysis

Abstract

Provided is a household cardiac monitoring system based on electrocardio and cardiac sound analysis. The system comprises a portable electrocardio and cardiac sound meter and its disposable application; the disposable application comprises a paster with a viscose layer; the paster is provided with a cardiac sound probe and multiple electrocardio electrodes; the cardiac sound probe and the electrocardio electrodes are exposed from the viscose layer; electrocardiogram and phonocardiogram are input to the electrocardio and cardiac sound meter; a same timeline is used for the real-time synchronously acquired electrocardiogram and phonocardiogram and the user's heart rate is obtained from the electrocardiogram; identifying electrocardio characteristics in the electrocardiogram and locating phonocardiogram using the electrocardio characteristics and finding cardiac sound characteristics; when R wave and first cardiac sound S1 do not appear correspondingly , or T wave and second cardiac soundS2 do not appear correspondingly, or the first cardiac sound S1 is abnormal or the second cardiac sound S2 is abnormal, then outputting cardiac abnormality alarm. The invention has the advantages ofbeing able to simultaneously monitor the electrocardio and the cardiac sound signals, and locating the cardiac sound characteristics by the electrocardiographic characteristics, thereby facilitating the user to monitor the heart state at home.

Description

technical field [0001] The invention relates to a home heart monitoring system. Background technique [0002] In the human heart, the sinoatrial node automatically and rhythmically generates current, and the current is transmitted to various parts of the heart in the order of conduction tissue, thereby causing the contraction and relaxation of cardiomyocytes. The excitement from the sinoatrial node is transmitted to the atria and ventricles in a certain way and process, causing the excitement of the whole heart. Therefore, the direction, route, sequence and time of the electrical changes occurring during the excitation of each part of the heart are regular. This bioelectrical change is reflected to the body surface through the conduction resistance value and body fluid around the heart, so that all parts of the body undergo regular electrical changes in each cardiac cycle. The electrical change curve of the heart recorded by placing the guide motor on a designated part of ...

AI Technical Summary

Problems solved by technology

[0004] There have been many attempts at home and abroad on the joint monitoring of heart sounds and ECG, but the previous cardiac function detectors were limited to the traditional digitization of cardiac auscultation, and did not fully utilize the clinical application value of heart sounds, nor did they integrate heart sounds Correlation with ECG by physiological relationship for analysis of heart function

[0005] Moreover, the existing electrocardiogram and phonocardiogram still remain at the stage of manual reading, and the information of the electrocardiogram or phonocardiogram must be analyzed only by relying on the experience of doctors. Interpretation of the electrocardiogram to determine whether there is a heart disease or a hidden danger of the disease; it is not conducive to the self-monitoring of heart disease patients at home

[0006] The portable electrocardiograph that appears now can only monitor the ECG, but cannot monitor the heart sound, and the electrocardiometer only outputs the electrocardiogram, but does not send out whether the heart is abnormal. It still depends on professionals to interpret the electrocardiogram.
