Acquisition and analysis system of the ECG signal based on LabVIEW

In view of characteristics of the ECG signal is very weak and strong background noise, and treated with hardware before enter the enlargement step to avoid noise signal amplification with the useful signal at the same time; QRS wave is basis of analyzing important characteristic of the ECG signal, and uses Matlab biorthogonal spline wavelet function to do wavelet transform with the signal, and detects R wave; A large number signals need tremendous storage space for storing, and thus need to compress the data with Matlab wavelet packet function; LabVIEW acts as the professional development environment of virtual monitoring and control equipment, has good man-machine interface, and easy to setup system and reconstruct system and make custom function.
