Embodiment Construction

[0104] The principle of the present invention is: the electrical signal sent by the sinoatrial node is transmitted to the right atrium and the left atrium, and the excitement of the atrium is shown as the P wave of the electrocardiogram. Right ventricle, ventricular excitation is manifested as R wave on ECG, and ventricular repolarization is manifested as T wave on ECG. Ventricular repolarization awaits the next activation of the sinoatrial node. In the same cardiac cycle, the ECG should have P waves, R waves and T waves.

[0105] The generation of S1 is related to the closure of mitral valve (T1) and tricuspid valve (M1), and the generation of S2 is caused by the closure of aortic valve (A2) and pulmonary valve (P2). During one cardiac cycle, the phonocardiogram should have S1 and S2. When the cardiac cycle of the electrocardiogram does not correspond to the cardiac cycle of the phonocardiogram, it is likely that the state of the heart is abnormal.

Abstract

The method for correcting the position of the heart sound sensor based on the multi-channel heart sound includes the following steps: synchronously collecting and recording the electrocardiogram and the multi-channel phonocardiogram. Find the heart sound features of each phonocardiogram according to the ECG characteristics, and identify whether the heart sound sensor is located in the correct auscultation area. The invention has the advantages of being able to identify whether each heart sound sensor is located in the correct heart sound auscultation area, and being suitable for monitoring the state of the heart at home.

Description

technical field [0001] The invention relates to an analysis method of an electrocardiogram and a phonocardiogram, in particular to an analysis method of an electrocardiogram and heart sound suitable for home-use electrocardiogram and heart sound monitoring. 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 ...
