Problems solved by technology

According to actual monitoring requirements, the connection conditions of each ECG lead signal are different, and some lead signals are in a vacant state. Existing portable ECG devices often use a fixed-length data storage format. For vacant lead signals, a specific label is used. The data is filled, which greatly wastes the limited storage space; and all ECG data is stored in a large data block, without block storage, which is not conducive to data analysis, movement and storage

Embodiment Construction

[0024] based on the following Figure 1~3 Specific embodiments of the present invention will be described in detail.

[0025] The realization steps of the present invention are as follows:

[0026] Step 1. Collect signals from eight leads I, II, V1-V6 of ECG signals at fixed time intervals. In this embodiment, 5s is used as a time interval for recording, and this time interval can also be adjusted as required.

[0027] Step 2, encoding and storing the electrocardiographic signal collected each time as an information block, each information block includes an information header and subsequent data blocks;

[0028] Step 2.1, the information header stores the necessary information for parsing the data block, the necessary information includes the sampling frequency, the sampling accuracy of each signal channel, etc. In particular, the connection status of the eight lead signals is also stored;

[0029] Such as figure 1 As shown, it is a schematic diagram of connection state st...

Abstract

The invention discloses an electrocardiogram data storage method for multi-interconnection dynamic switching. The method is characterized by comprising the following steps of: 1, acquiring eight lead signals I, II, V1 to V6 in electrocardiogram signals at fixed time intervals; 2, coding and storing the electrocardiogram signals acquired every time to an information block, wherein each information block contains an information header and a subsequent data block; 2.1, storing and resolving the required information of the data block in the information header, and storing the link statuses of the eight lead signals; and 2.2, according to the link status of each lead signal stored in the step 2.1, only storing the data of the lead signals in the link statuses in a data block region without storing the data of other lead signals. The storage method not only occupies a small storage space, but also is convenient to resolve, move and store the data due to blocking storage.

Description

technical field [0001] The invention relates to an electrocardiographic data storage method, in particular to a multi-lead dynamic switching electrocardiographic data storage method. Background technique [0002] In the portable ECG device, because the signal recording time is long and the data volume is huge, the storage of ECG data has a particularly important position for the practicability of the device. According to actual monitoring requirements, the connection conditions of each ECG lead signal are different, and some lead signals are in a vacant state. Existing portable ECG devices often use a fixed-length data storage format. For vacant lead signals, a specific label is used. The data is filled, which greatly wastes the limited storage space; and all the ECG data are stored in a large data block without block storage, which is not conducive to data analysis, movement and storage. Contents of the invention [0003] The invention provides a multi-lead dynamic switc...
