Multi-channel heart sound sensor position recognition and correction method

Abstract

The invention provides a heart sound sensor position identifying and correcting method for multi-channel heart sounds. The method comprises the following steps that an electrocardiograms and multi-channel phonocardiograms are synchronously collected and recorded, wherein the multi-channel phonocardiograms correspond to auscultation areas respectively; heart electricity characteristics of each cardiac cycle are identified, and according to the heart electricity characteristics, the heart sound characteristics of each channel of phonocardiogram are correspondingly found; the S1 intensities and the S2 intensities of the heart sound auscultation areas are obtained respectively, and for the same cardiac cycle, whether the phonocardiograms accurately correspond to the auscultation areas thereofor not is judged according to the S1 intensities and the S2 intensities. The heart sound sensor position identifying and correcting method has the advantages that heart electricity signals and multi-channel heat sound signals can be monitored at the same time, the heart function is preliminarily identified, and the method is suitable for home monitoring of the heart state.

Description

Technical field

[0001] The present invention relates to an analytical method of an electrocardiogram core diagram, particularly an electrocardiological heart sound analysis method suitable for home cardinal core sound monitors. Background technique

[0002] In the human heart, the sinus junction is automatically, there is a rhythmic production current, and the current is transmitted to the individual parts of the heart in the order of the conduction tissue, thereby causing shrinkage and diastolication of myocardial cells. The excitement from the sinus knot is transmitted to the atrium and ventricles in turn, causing the excitement of the entire heart in order to pass in a certain approach and process. Therefore, the direction, pathway, order and time of the electroinciors, the order, the order, and the time of the extension of the heart. This bioelectrical change reflects the body-resistant value and body fluid around the heart, so that the body is regularly changed in each of ea...
