| 摘 要： | 实时动态心电图仪一直是临床广泛应用的医疗器械之一,为使对心电信号(ECG)的采集和初步处理比传统测量方法更加准确可靠,利用USB串行通信和计算机组成了高智能化心电监护仪;该设计以ATmega64及高速16位ADC(AD7677)为核心,利用双极性肢体导联采集微弱电压经放大,带通滤波,工频肌电陷波后通过模数ADC(AD7677)进行采样,而研制了一套高分辨心电信号采集电路,数据最终送入计算机进行处理;结果表明心电信号纯净并可实时显示。

| Abstract: | Telecardiology real-time monitoring apparatus has been widely used in clinical application.To enable to collect and process electrocardio(ECG) singap more reliablg and exacttg than traditional methods,using USB with PC to compose a intelligentized electrocardioscanner is reapized.This design mainly realizes ATmega64 and 16 bits high resolution ADC(AD7677) utilize Electrocardio leads to collect weak signal,amplifies the signal and by the band-pass filter,uses 35Hz50Hz notch circuit,samples with ADC(AD7677) to design a high-resolution acquisition circuit of ECG,finally processes by computer.The result shows that the circuit can receive real-time,pure electrocardio signal. |
