【摘要】 针对心律不齐、心肌缺血、早搏等心脏疾病的相关人群，设计了一款便携式心电监测设备，用于疾病的早期发现和预防。首先对一款型号为RT1025的前端心电信号采集芯片进行了研究，并针对肌电噪声、50 Hz工频干扰等常见噪声开发了去噪声无限冲激响应滤波算法，最后完成了心电数据采集和通信的程序设计。该设备工作状态稳定，数据采集和控制简单，为便携式心电采集设备的设计提供了参考依据，对于预防和实时监测心血管方面的疾病具有重要意义。更多还原

【Abstract】 A portable electrocardiogram(ECG) monitoring device is designed for people with arrhythmia, myocardial ischemia, premature beats, and other heart diseases, and it is used for disease detection and prevention. In this paper, the RT1025 front-end ECG signal acquisition chip is studied first, followed by the development of a denoising infinite impulse response filtering algorithm for common noise such as electromyogram noise and 50 Hz power frequency interference, and the completion of program design for ECG data acquisition and communication. This equipment is stable in working condition, simple in data acquisition and control, and serves as a model for the design of portable ECG acquisition equipment. It is also important for the prevention and real-time monitoring of cardiovascular diseases.更多还原
