Abstract

The invention discloses a portable hand-held ECG monitor and a QRS wave detection method. The portable hand-held ECG monitor includes a hand-held structure; the hand-held structure is connected to an induction device through a signal processing module mounting body. The ECG monitor of the present invention is simple and convenient. It is feasible for the user to hold the ECG sensor with his left hand or right hand, and just stick it on the chest. There is no special requirement for the attachment position, and the sensor has high sensitivity. Even if the clothing is thick, it can generate the corresponding ECG waveform, which can be used directly without any preparation in advance; motion artifacts are eliminated, and the flexible sensing electrodes are used to fit the clothes better. The method of the present invention has less calculation amount and can be realized on a single-chip microcomputer; has strong real-time performance, and can quickly display the heart rate value of the ECG signal in real time; has good adaptability, and can well adapt to different individuals with different ECG amplitudes. It can accurately calculate the heart rate value under the condition of signal fluctuation caused by mobile ECG contact.

Description

technical field [0001] The invention relates to the field of ECG signal detection, in particular to a portable hand-held ECG monitor and a QRS wave detection method. Background technique [0002] Bioelectricity reflects the important information of various physiological states of the human body. The detection and recording of various bioelectricity of the human body has become the key basis for grasping the health of human organs. The activity of the heart causes the potential distribution on the surface of the human body to be different, thus generating electrocardiography. Electrocardiogram is an important means of detecting heart disease. The three most deadly diseases in China are stroke, coronary heart disease and chronic obstructive pulmonary disease, and heart disease accounts for two. [0003] In the traditional ECG measurement system, Ag / AgCl disposable electrode sheets or suction cups with conductive glue are usually used. The defect of this type is that it must b...
