Abstract

A novel portable and wireless biomedical monitoring system featuring on demand wireless data transmission of ECG signals and time-frequency HRV analysis for personal and home healthcare applications is presented in this work. In order to provide comfort and convenience to patients, the device's size, power consumption and portability are of first priority. The ECG processor based on previous hardware design [1] acquires three-channel ECG biomedical raw data through an analog front-end (AFE) circuit, and it measures the time between successive heart beats on lead II as RR intervals for HRV analysis. Functions such as QRS complex peak detection, RR intervals calculation, and time-frequency analysis of HRV have also been developed in hardware. A real-time HRV analysis processor is realized by employing a Lomb periodogram for time-frequency power spectral density (PSD) analysis of the heart rate. The proposed ECG monitoring system has been implemented in Field-Programmable Gate Arrays (FPGA) and it features high integration density, portability, wireless transmission and low cost.

一种新型的基于fpga的心电处理器无线生物医学监护系统

本文介绍了一种新型便携式无线生物医学监测系统，该系统具有随需应变的心电信号无线数据传输和时频心率波动分析功能，适用于个人和家庭医疗保健应用。为了给患者提供舒适和方便，设备的尺寸、功耗和便携性是重中之重。基于先前硬件设计的心电处理器[1]通过模拟前端(AFE)电路获取三通道心电生物医学原始数据，并测量导联II连续心跳间隔时间作为RR间隔，用于HRV分析。硬件上还开发了QRS复峰检测、RR区间计算和HRV时频分析等功能。采用Lomb周期图对心率进行时频功率谱密度(PSD)分析，实现了实时HRV分析处理器。该心电监护系统采用现场可编程门阵列(FPGA)实现，具有集成度高、便携、无线传输、成本低等特点。
