| Abstract: | In this paper,a T wave alternans detection system based on wireless and USB communication is presented.The ECG signal is amplified in the first step.The amplifier has a gain of 2000 and the CMRR is 80dB.Then the signal is sampled with a 12-bit AD converter.At last,the sample result is transmitted to the PC via wireless communication and USB bus. In the PC,the T wave alternans are detected using the spectral method.Results show that this system has high data transmission rate and real time data processing ca... |
