Embodiment 1

[0028] figure 1 Shown is a flow chart of the ECG detection method provided by Embodiment 1 of the present invention. figure 2 Shown is the circuit principle block diagram of the ECG detector provided by Embodiment 1 of the present invention. image 3 Shown is a schematic diagram of the ECG detector provided by Embodiment 1 of the present invention. Figure 4 Shown is a schematic diagram of the use mode of the electrocardiogram detector provided by the present invention. Please also refer to Figure 1 to Figure 4 .

[0029]The basic process of the electrocardiographic detection method is: acquiring the electrocardiographic signal of the subject (such as step S101 ), and extracting the characteristic parameters of the acquired electrocardiographic signal (such as step S102 ). Matching the extracted characteristic parameters with the standard ECG signal parameters in the preset templates in the template library (such as step S103 ). Then, judge whether the matching is succe...

Embodiment 2

[0049] Such as Figure 5 with Image 6 As shown, this embodiment is basically the same as Embodiment 1 and its variations, except that the number of ECG measuring electrodes 1 and impedance measuring electrodes 71 is three. Two of the ECG measurement electrodes 1 are used to extract ECG signals, and the third ECG measurement electrode 1 is electrically connected to the compensation module 113 . The other end of the compensation module 113 is electrically connected to the feedback end of the ECG amplifier 112, and a common-mode negative feedback is established between the feedback end of the ECG amplifier 112 and the input end of the ECG signal, so as to offset power frequency interference to the greatest extent and improve detection accuracy. In this embodiment, the compensation module 113 is composed of a plurality of feedback resistors and operational amplifiers. The third electrocardiographic measurement electrode 1 can be arranged on the leg of the subject. However, the...

Abstract

The invention provides an ECG detection method and a detector. The ECG detection method includes the steps that an ECG signal of a tested person is acquired; the characteristic parameter of the acquired ECG signal is extracted; the extracted characteristic parameter is matched with a standard ECG signal parameter in a preset template in a template library; whether the extracted characteristic parameter is successfully matched with the standard ECG signal parameter in the preset template in the template library or not is judged; if yes, reliability calculation is started; if not, the acquired ECG signal serves as a new preset template to be updated into the template library. The problem that because a traditional ECG detector can not judge the credibility of the ECG signal, a doctor can not give effective diagnosis judgment, and seriously, wrong judgment even happens is avoided.

Description

technical field [0001] The invention relates to the field of medical electronic equipment, and in particular to an electrocardiogram detection method and a detection instrument. Background technique [0002] Arrhythmias are associated with most cardiovascular diseases. For the diagnosis of arrhythmia, the common way in the hospital is to use an electrocardiogram machine or a holter system. [0003] The electrocardiogram machine can accurately record the ECG waveform in a short period of time, but due to the uncertainty of heart disease, this method obviously has great limitations, and it is likely that it cannot measure abnormal waveforms. The holter system can continuously record the dynamic ECG information when the patient wears the handset for a long time (about 24 hours), and then transmit it through the network or the patient directly takes it to the hospital host system to complete the analysis. However, the real-time performance of this method is poor, and the sub-m...
