Low-power consumption portable electrocardiograph monitor and control method thereof

Abstract

The invention relates to a low-power consumption portable electrocardiograph monitor and a control method thereof, which belongs to the field of medical appliances. The portable electrocardiograph monitor comprises an electrocardiosignal collection unit, an electrocardiosignal analysis and storage unit and an upper computer. The control method comprises the following steps of: step 1: carrying out digital filtering to collected signals by using a wavelet entropy optimal threshold denoising method; step 2: carrying out rejection of baseline drift to the signals processed by step 1 by using a morphological filtering method; and step 3: carrying out disease classification to the signals processed by step 2 by using a support vector machine algorithm. The invention has the advantage of high integrity, and has the characteristics of portability, compactness and economy.

Description

technical field

[0001] The invention belongs to the field of medical devices, and in particular relates to a low-power dynamic electrocardiogram monitor and a control method thereof. Background technique

[0002] According to an authoritative survey, cardiovascular disease has become one of the main causes of death in the world. Cardiovascular diseases account for about one-third of all deaths each year. Therefore, the discovery, prevention, treatment and rescue of abnormal ECG are of great significance for saving lives. Electrocardiogram (ECG) is recorded through the human body surface to reflect the bioelectrical changes accompanied by the generation, conduction and recovery of cardiac excitation in each cardiac cycle. As a measure of electrical activity that mainly reflects cardiac excitation, it has always been a research focus in the field of heart disease diagnosis. However, since the abnormality of the ECG signal is accidental, and the routine ECG acquisition proce...
