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] A specific embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 3 .

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

[0026] Step 1. Collect ECG signals from eight leads I, II, V1-V6 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 ECG signals 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] As shown in Figure 1, it is a schematic diagram of the connection state storage of the eight lead si...

Abstract

The invention discloses an electrocardiogram data storage method for multi-lead dynamic switching. The method comprises the following steps: step 1, collecting eight lead signals including V1 to V6 of electrocardiosignals I and II at fixed time intervals; step 2, storing codes of electrocardiosignals collected into an information block, wherein each information block contains one information header and subsequent data blocks; step 2.1 storing necessary information of the data blocks in information headers and storing connection states of the eight lead signals; step 2.2 only storing data of the lead signals in the connection state in a data block region according to connection states of the lead signals stored in the step 2.1 without storing other lead signals. The electrocardiogram data storage method for multi-lead dynamic switching has the following beneficial effects: little storage space is occupied; a block storage method is utilized so as to facilitate analyzing, moving and storing data.

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...
