Abstract

The present invention discloses a method and a device for identifying electrocardiogram image feature points, and relates to the technical field of portable medical devices. The method comprises the steps of: obtaining original signals of electrocardiogram images; performing filtering processing for the original signals to obtain signals after filtering; based on the filtered signals, determininga feature point R; and determining other feature points based on the feature point R. The method and the device for identifying electrocardiogram image feature points mainly solve the problem that theQRS feature wave group diagnosis is difficult, are mainly used for a current portable wearable device, and a good diagnosis effect on various types of heart disorder.

Description

technical field [0001] The invention relates to the technical field of portable medical equipment, in particular to a method and device for identifying feature points of electrocardiogram images. Background technique [0002] The electrocardiogram is a curve formed by a series of physiological electrical activity processes generated by the self-discipline and conduction of cardiac muscle cells in the human heart. It is one of the most important tools for diagnosing heart diseases. It has been used clinically for more than a hundred years since it was discovered by Willem Einthoven in 1901 and has recorded clear physiological electrical curves from the body surface. More than one hundred years of clinical use history has made electrocardiogram a relatively mature technology, and the detection of electrocardiogram is accurate, the method is operable, and the harm to patients is small, making the detection of electrocardiogram an indispensable method for heart disease treatment...
