The purpose of dynamic play software kit has two, and the one, playback is afterwards done in the storage of cardiac monitoring data, can help the needs of doctor's diagnosis, the consultation of doctors and analysis.The second, incidental ecg database is the large-scale ecg database of our a typical medical record finishing, by this data base's dictionary effect, can help the doctor to do reference when diagnosis is judged doing greatly.Ecg database is made up of a series of file, these files are organized according to certain rules and mode according to each, deposit the different information of an association database separately, comprise the header file (hea file) of describing the ecg database file group, commentary file (atr file) and the ecg database signal data file (dat file) of describing the explanation of ecg database signal data file.
The hea file is that file is made up of the attribute of every data field signal data file, is file specification with the unit of going with the pure character text file of hea as file suffixes, the attribute of the file of every row with the space as separation.
The atr file is to be the file of the binary data format of file suffixes with atr, comprising for the commentary information of signal data file, the commentary information of signal data file is respective signal data file (dat file), describes the situation of each signal period of signal data file.These commentary information are the clear signal data according to the explanation of a series of code data structure correspondence, so need the inquiry synopsis could determine the detailed of commentary.
The dat file is to be the binary data file of filename suffix with dat, with binary mode storage ecg signal data, file according to certain data format (according in the atr file to the definition of data form) data are read and write, one group of sampled data is finished in each read-write, is stored in the specific data structure according to signal sequence.
Because sampling has certain frequency, so can determine the relative time of sampling according to the numerical order of sampling, sampling has certain numerical value, so can determine the voltage amplitude of sampled representation according to the numerical value of sampling, the data of comprehensive above two aspects can be determined the demonstration of signal data file
The target of dynamic electrocardiogram (ECG) data storehouse player is to use the C++Builder development language, makes full use of the advantage of Windows graphical interfaces, and the mode of playing is carried out dynamic play to the electrocardiogram (ECG) data database data to roll.Comprise and open file, preserve file, print screen, clear screen, time redirect, comment and show, select signal data to show, search functions such as abnormal data signaling point, user friendly operation.
