Abstract

In this study, we report features related between an electrocardiogram (ECG) and a blood pressure pulse wave measured by the fabricated wearable device. The device consists of MEMS 3-axis force sensors, an electrocardiograph, a signal processing board and a fixed band. This device measures blood pressure using force sensors that are placed on the surface of the skin over a blood vessel. During experimentation, blood pressure was varied by breath holding while simultaneously measuring the blood pressure pulse wave and the ECG. Furthermore, features derived from the blood pressure pulse wave, its differential waveforms, such as the acceleration pulse wave, and the ECG were compared. The correlation coefficient between the pulse pressure of the blood pressure pulse wave and the P wave amplitude of the ECG associated with hypertension was 0.976. Moreover, the correlation coefficient between the augmentation index of the blood pressure pulse wave and the ST segment elevation of the ECG, which is used for diagnosis of myocardial infarction, was 0.915.

摘要

在本研究中，我们报告了通过所制造的可穿戴设备测量的心电图（ECG）与血压脉搏波之间的相关特征。该设备由MEMS三轴力传感器、心电图仪、信号处理板和固定带组成。该设备使用放置在血管上方皮肤表面的力传感器来测量血压。在实验过程中，通过屏气改变血压，同时测量血压脉搏波和心电图。此外，还比较了从血压脉搏波及其微分波形（如加速度脉搏波）以及心电图中得出的特征。与高血压相关的血压脉搏波的脉压与心电图P波振幅之间的相关系数为0.976。此外，用于诊断心肌梗死的血压脉搏波的增强指数与心电图ST段抬高之间的相关系数为0.915。
