Abstract

The present invention discloses an electrocardiogram signal warning device, comprising a control module, an electrocardiogram measuring module and a recording module electrically connected to the control module respectively, and an warning module connected to the control module by signal. The electrocardiogram measuring module measures the real-time electrocardiogram signal of the user, transmits the real-time electrocardiogram signal to the control module for consistency comparison with a reference electrocardiogram signal of the user, and when the degree of loss of consistency is greater than a preset allowable range, the warning module is made to issue a warning.

Description

ECG signal warning device

technical field

The invention relates to a monitoring method for electrocardiogram signals, in particular to an electrocardiogram signal warning device which can avoid false alarms.

Background technique

Arrhythmia is a common symptom of heart-related diseases. Currently, the detection of heart rhythm/electrocardiogram is mainly monitored by ECG detection devices. Signal processing technology can extract favorable ECG signals from ECG (electrocardiogram) signals. Parameters used to identify and interpret to facilitate classification of the user's cardiac state. For example, certain characteristics of the ECG signal may indicate a normal ECG signal, an abnormal ECG signal, or an ECG signal with arrhythmia.

Most of the existing ECG monitoring and warning devices are based on the relatively normal ECG signal design warning conditions in the ECG signal textbooks, which cannot meet the requirements of personalization and differentiation. The ECG shown in Figure 6 is regarded as relatively normal by traditional textbooks. electrocardiogram. Such an ECG monitoring and warning device can be applied to the general population, but it is not applicable to people with existing heart disease or those who need exercise rehabilitation due to heart disease. For example, Figures 7 to 8 are medically diagnosed as a right The waveform of the ECG with branch obstruction, a left bundle branch obstruction, is different from the typical normal waveform in medicine.

When the existing ECG monitoring and warning device is used for people with existing heart disease, because the ECG signal of the monitoring object itself is different from that of ordinary people, and the traditional heartbeat detection device only uses the traditional typical ECG signal as the judgment standard, it is easy to misunderstand. Sending an alarm, once there are many false alarms, the user either ignores the alarm or simply discards it.

SUMMARY OF THE INVENTION

Since the conventional ECG detection device is based on a typical ECG signal, it is easy to give a false alarm when it is used for a person with an existing heart disease. Therefore, the present invention utilizes the function of self-setting alarm reference to achieve the effect of avoiding false alarms.

In order to achieve the above object, the present invention provides an ECG signal warning device, comprising a control module, an ECG measurement module and a recording module respectively electrically connected to the control module, and a warning module signally connected to the control module, in:

The ECG measurement module measures a user's real-time ECG signal, and transmits the real-time ECG signal to the control module, the recording module stores a user's reference ECG signal, and the control module reads the reference ECG signal of the recording module ECG signal and execute a comparison procedure, the comparison procedure compares the consistency of the real-time ECG signal and the reference ECG signal, when the degree of inconsistency between the real-time ECG signal and the reference ECG signal is greater than a preset allowable The comparison program makes the control module control the warning module to issue warnings.

Further, the reference ECG signal of the user according to the present invention is the ECG signal obtained by the ECG measurement module measuring the user in a reference time period.

Further, the reference ECG signal of the user according to the present invention is an ECG signal obtained by measuring the user in a reference time period by an external ECG measuring device.

Furthermore, the comparison procedure of the present invention is to compare the consistency of the real-time ECG signal and the reference ECG signal displayed on the ECG in the envelope waveform, frequency domain or time domain.

Furthermore, the preset allowable range of the present invention is the number of times that a specific ECG signal occurs within a certain period of time compared to the reference ECG signal in the real-time ECG signal.

Preferably, the warning module of the present invention is signal-connected to the control module in a wireless manner.

When the present invention is used to monitor a user with an existing heart disease, the user's reference ECG signal will be stored in the recording module first. Although the reference ECG signal is not normal relative to the relatively normal ECG signal in the textbook, in the present invention During the execution process, the reference ECG signal will be used as the comparison basis for the control module to execute the comparison program. Then the ECG measurement module continuously measures the real-time ECG signal of the user, and compares the consistency between the real-time ECG signal and the reference ECG signal by executing the comparison program. The degree of signal loss of consistency is greater than a preset allowable range, and the comparison program uses a wireless or wired signal connection to make the control module control the remote or near-end warning module to issue a warning, indicating to the medical personnel and police the use of the abnormal situation of the user, or warn the user that the current heart rhythm is abnormal.

The advantages of the present invention are:

The control module executes the comparison procedure based on the user's baseline ECG signal as a comparison basis. When the user has a heart disease, the comparison basis is derived from the user's general heart rhythm, rather than using a textbook comparison. The normal ECG signal is used as a single comparison basis, so when using the present invention to monitor the heart rhythm of different users, individualization and differentiation can be satisfied for different people, so as to avoid continuous false alarms by the warning module, so as to effectively monitor users The effect of the heart rate condition makes the user willing to use the present invention as a means for monitoring the heart rate.
