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 capability, and can realize the detection of T wave alternans.
