Abstract :
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 AID 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 1000 Hz for each lead with a high resolution of 16-bit and the data transmitting speed for the 2.4 GHz RF transceiver and the USB bus are 250 kbps and 12 Mbps. 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.
