摘要:
心脏电活动和机械活动的同步监测是全面评估心功能的关键。本研究设计一种可同步采集心电信号和胸部机械振动信号的穿戴式监测设备，以单片机为核心，利用心电采集芯片检测心电信号，利用加速度传感器同步采集心脏在体表的机械搏动信号。信号采集后，通过上位机分析软件识别心电和机械信号特征点，估算心功能指标。实验结果发现所估算的心功能指标与超声心动图获得参数具有较强的相关性，表明基于心电信号和机械信号同步传感的穿戴式监测方法可用于高风险心血管疾病患者的日常心功能监测。
Abstract:
Abstract: The simultaneous monitoring of the electrical and mechanical activities of the heart is critical to the comprehensive assessment of cardiac function. A wearable monitor that can synchronously collect electrocardiogram (ECG) signals and chest mechanical vibration signals is designed, with a single-chip microcomputer as the core, using ECG acquisition chip to detect ECG signals, and accelerometers to synchronously collect seismocardiogram (SCG) signals. After signal acquisition, the ECG and SCG signal characteristic points are recognized using the host computer analysis software for cardiac function estimation. The experimental results show that the estimated cardiac function indicators have strong correlations with the echocardiogram parameters, indicating that the wearable monitor based on synchronous sensing of ECG and SCG signals can be used for daily cardiac function monitoring in patients with high-risk cardiovascular diseases.
