This paper introduces an ECG real time monitoring system based on LabVIEW.With Wavelet transformation,the original ECG signals are processed to increase the accuracy of R peak detection.The feature of real time in this system is ensured by the application of simplified algorithm.The result panel offers various types of HRV information in time domain,including numerical and graphical displays which make the data more intuitional and more convenient to obtain.The system runs well in lab and the result is acceptable.
