This semester has been doing research on ECG information, all based on Mitbih arrhythmia database, so the contents of the Mit-bih repository.
1.mit-bih download of the repository:
DATABASE DOWNLOAD and related repositories: Introduction
2. Stored format:
The following screenshot is a total of 48 numbers for the library found on the official website.
There are three kinds of stored formats:
(1) [. ATR]: To note the file. Binary storage. Through this file, we can read about beat species, such as normal beat, rbbb beat, etc.
(2) [. dat]: The digital file, in accordance with the binary storage stored, stored signal. Save two numbers per three characters, one 12bits.
(3) [. Hea]: Head file, stored as ASCII code characters. You can use the browser to open directly, including some basic constants of the signal.
3. Reading of the ECG (1) Use the official web site tool to access
Database: Select the library, here we choose Mit-bih Arrhythmia Database
Record: Select symbol
Each message in Signals:mitbih arrhythmia contains two guides, so you need to select the path you want.
And then it's the choice of the numbers.
On the right is the tool box, and you can choose the function you want it to be.
(2) In the window below the interface to read: A. Use Cygwin to read and connect to the signal: http://physionet.org/physiotools/wfdb-windows-quick-start.shtml
Let's talk about simple installation steps and notes: The installation of Cygwin, Cygwin is a UNIX system in Windows. The Cygwin download connection can be found in the connection above, the 64-bit window can operate 32-bit and 64-bit Cygwin, while the 32-bit window Gion can run 32-bit Cygwin. In the case of a 64-bit Windows system, it is suggested that you install 32-bit Cygwin, and the installation speaks of "Since XView is a 32-bit toolkit, it's not possible to build a 64-bit WAVE, but It is possible to build and run a 32-bit WAVE with cygwin/32 on either 32-or 64-bit Windows. " Involving the use of Xview, Xview is a 32-bit toolkit. Cygwin's 32-bit and 64-bit can also be installed at the same time, and will be stored in the "Cygwin" and "Cygwin64" folders in the C tray after self-installation. In the Cygwin installation process, you need to select the kit you want to install, http://physionet.org/physiotools/cygwin/will have the toolkit you need to use the Wfdb library, and you can choose the package you need.
If you use Cygwin later to do other tools, missing a kit, and re-install the process, you can choose the toolkit you need and add it to the WFDB toolkit for convenience.
The rest of the installation steps are basically the same as the steps of the Linux installation toolkit.
Note that in the last step is the library connection, you need to search your C plate in the Cygwin folder "LIBWFDB.DLL.A" storage location, and sometimes not in the/use/bin/.
for the use of the Wfdb, you can check stated expiry refer files:http://download.csdn.net/detail/u010060391/8395183
http://download.csdn.net/detail/u010060391/8395187
B. Use MATLAB to read the connection: http://physionet.org/physiotools/matlab/wfdb-app-matlab/first is the installation of the toolbox, according to the connection on the instructions.
I also have the operation in MATLAB, basically there is also the Internet you can search for a lot of ECG MATLAB to read the program. The WFDB Toolkit is sufficient to provide a number of functions, including. ATR. dat files, which can be used more easily. In Linux, MacOS has a corresponding Wfdb library installed, can be found in http://physionet.org/physiotools/. There are other questions that you can continue to communicate.
Mit-bih and use of arrhythmia database
