Design of High Frequency Ventricular Repolarization Wave Detection System Based on Wireless USB Communication
This paper focuses on the design and implementation of a beat-to-beat detecting system for High Frequency Ventricular Repolarization Wave (HFVRW) based on wireless USB communication. The HFVRW and reference ECG signals are amplified and sampled firstly, and then the A/D result is transmitted to the host PC through wireless circuit and USB interface. Data analysis and displaying will be done on the host PC at last. To detect faint HFVRW signal from noise and interference, this system is well designed with many characteristics, such as the common mode rejection ratio (CMRR) of the amplifier is greater than 80 dB, the sampling frequency is 1000Hz for each lead with a high resolution of 16-bit and the data transmitting speed for the 2.4GHz RF transceiver and the USB bus are 250kbps and 12Mbps. The experimentally results show that this system can reject noise effectively, transmit data high-speedily and process data real-timely, and so it meets the design requirement of HFVRW detection.
