单导联心电信号采集与显示系统的设计

Design of Single Lead ECG Signal Acquisition and Display System

近年来心血管疾病的发病率正在逐年上升,医生对于心血管疾病的诊断仍然将测量心电图作为最主要的辅助检查手段,但是目前静态心电图仪器仅可以进行瞬时采样且仅能记录患者部分心电情况,对于潜伏性疾病较难以及时发现,而动态心电图仪器佩戴复杂且即时性差,故论文设计了一套基于FPGA的单导联心电采集与显示系统,并通过上位机对其采集的波形进行显示。经过测试验证,单导联心电采集与显示系统运行良好,能够有效地检测到生物电信号,佩戴方便且能够辅助医生提升诊断决策的效率,给医疗器械的研究提供了一种新的研究方向。

In recent years,the incidence of cardiovascular disease has been increasing year by year.Doctors still use ECG measurement as the main auxiliary examination method for the diagnosis of cardiovascular disease.However,at present,static ECG instruments can only perform instantaneous sampling and can only record part of the ECG of patients,it is difficult to detect latent diseases in time,and the dynamic ECG equipment is complicated to wear and has poor immediacy.Therefore,this paper designs a single-lead ECG acquisition and display system based on FPGA,and displays the collected waveforms through the host computer.After testing and verification,the single-lead ECG acquisition and display system works well,can effectively detect bioelectrical signals,is easy to wear,and can assist doctors to improve the efficiency of diagnosis and decision-making,providing a new research direction for medical device research.
