摘要
在动态心电图机的基础上,开发了一个与之配套使用的FPGA实验电路板,可以实时提取心电信号的波形,对心脏性猝死发出预警,弥补了现有的便携式心电图机(如Holter)难以实时分析诊断的不足。该系统可以结合VHDL与SOPC,在FPGA电路板上实现对心电数据的读取、解码、运算,并用串口将结果发送到PC端,用Matlab的GUI界面显示出来。经测试,该系统性能优良、功耗小、方便携带。
A FPGA-based portable ECG monitoring system is designed. The FPGA PCB is developed based on the ECG amplifier. The FPGA PCB can accomplish ECG waveform feature extraction and predict sudden cardiac death in real time, which overcomes the shortcoming of present portable ECG monitoring sys- tem（ e. g. Holter）, that is lack of real-time analysis ＆ diagnosis. This monitoring system combines VHDL and SOPC, receiving ECG waveform, decoding the waveform, extracting waveform feature and predicting abnor- mal ECG by outputting through the FPGA PCB. It sends the result to PC through serial port. The final result can be displayed on GUI interface by Matlab. The test shows that the system has a good performance with low power consumption and easy portability.
