Example Embodiment

[0076] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0077] like figure 1 Shown, in one embodiment, a kind of detection method in dynamic electrocardiographic signal data, comprises the steps:

[0078] Step S110, preprocessing the original dynamic ECG signal data.

[0079] In this embodiment, the original dynamic ECG data will be obtained by continuously recording the wearer's ECG signal. The original dynamic ECG signal is preprocessed to filter baseline drift and power frequency interference, so that the baseline position of the filtered original dynamic ECG signal data is near 0.

[0080] Further, the preprocessing of the original dynamic ECG da...

Abstract

The invention provides a detecting method and device for dynamic electrocardio signal data. The method includes: preprocessing original dynamic electrocardio signal data; performing form conversion on the processed original dynamic electrocardio signal data; obtaining dynamic electrocardio signal data sections, with QRS composite waves, in the dynamic electrocardio signal data output after form conversion according to a first threshold and a second threshold, searching and positioning in the dynamic electrocardio signal data sections to obtain the QRS composite waves; updating the first threshold and the second threshold according to the original dynamic electrocardio signal data in preset time. The device comprises a preprocessing module, a form converting module and a searching module. By the method and device, artifact judgment, caused by using single threshold, in the dynamic electrocardio signal data.

Description

technical field [0001] The invention relates to signal processing technology, in particular to a detection method and device in dynamic electrocardiographic signal data. Background technique [0002] The wearer of the ECG acquisition device will record the ECG signal continuously for 24 hours or even longer in normal life to obtain the dynamic ECG signal data, and then process the dynamic ECG signal with the help of a computer. [0003] Since the wearer cannot be stationary, the ECG signal recording by the ECG acquisition device is often subject to various interferences, causing artifacts to exist in the dynamic ECG signal data. For example, when the wearer walks, climbs stairs, lifts heavy objects, or even sleeps, he will inevitably touch or pull the lead wires of the ECG acquisition device, and the resulting interference will cause artifacts that will bring ECG traces ups and downs, even obliterating normal ECG signals. [0004] Valuable ECG information is often included...
