摘要
为了能够对心血管疾病患者实时监测心电信号,以便提供及时的救助,本文研究了一套远程心电监护系统的硬件设计,通过保护与输入缓冲电路、前置放大及右腿驱动电路、滤波电路、后置放大及电平抬升电路实现心电信号的放大、滤波。目前监护系统的设计已取得阶段性的成果,能够在强烈的噪声中,采集到准确的心电信号,尽可能地减小了失真。
In order to real-time monitoring of electrocardiogram （ECG） in patients with cardiovascular disease, so as to provide timely rescue, The hardware design of remote wireless electrocardiogram （ECG） monitoring system is designed in this paper, through the protection circuit with the input buffer, preamplifier and driven right leg circuit, filter circuits, the uplift of the amplification level circuit to realize ECG amplifying, filtering. The present monitoring system design has achieved initial results, can in the strong noise, to collect accurate ECG signal, as far as possible to reduce the distortion.
