【摘要】：随着心血管疾病患病人数的迅速增长,实时监测心脏健康的需求也与日俱增。而传统心电监护设备因导联数众多、缺乏便携性,无法满足患者需求,因此研究更智能、更便捷的可穿戴心电监护设备十分必要。目前,单导联可穿戴心电监测设备因为导联数少、体积小、便携舒适等特点,在人体心电信号的监测领域逐渐成为热点。然而对于其检测位置、该位置单导联心电信号可靠性以及医疗辅助诊断价值还没有明确的说明。本论文设计了一套穿戴式4电极方形心电监测系统,进行多通道单导联心电信号检测;相应地提出了一种分层网格分布测试评估方法,进行心电信号的采集和评估,最终确定了最佳的单导联心电信号检测位置。此外,本文自制了一套单导联心电监测系统,对最佳测量位置处的单导联心电信号进行了临床研究。结果表明,实验确定的最佳测量位置处的心电信号特征明显。临床试验结果也表明,该位置处的心电信号包含的心率、QRS波群宽度以及P波宽度等特征与标准心电监护仪基本一致。因此本文确定的最佳测量位置处的单导联心电信号具备一定的医疗诊断价值。
[Abstract]:With the rapid increase in the number of cardiovascular diseases, the need for real-time monitoring of heart health is increasing. The traditional ECG monitoring equipment is lack of portability and can not meet the needs of patients, so it is necessary to study more intelligent and convenient wearable ECG monitoring equipment. At present, single lead wearable ECG monitoring equipment has become a hot spot in the field of human ECG monitoring because of its small number of leads, small volume, portable comfort and so on. However, the reliability of single lead ECG signal and the value of medical auxiliary diagnosis are not clearly explained. In this paper, a wearable four-electrode square ECG monitoring system is designed to detect multi-channel single-lead ECG signals, and a hierarchical grid distribution testing and evaluation method is proposed to collect and evaluate ECG signals. Finally, the best detection position of single lead ECG signal is determined. In addition, a set of single lead ECG monitoring system is made in this paper, and the single lead ECG signal at the best measuring position is studied clinically. The results show that the electrocardiogram (ECG) characteristics at the best measuring position determined by the experiment are obvious. The clinical results also show that the ECG signals at this position contain the characteristics of heart rate, QRS wave group width and P wave width, which are basically consistent with the standard ECG monitor. Therefore, the single-lead ECG at the best measuring position is valuable for medical diagnosis.
