ICG (impedance cardiography) and ECG (electrocardiography) provide important indications about functioning of the heart and of overall cardiovascular system. Measuring ICG along with ECG using wearable devices will improve the quality of health monitoring, as ICG points to important hemodynamic parameters (such as time intervals, stroke volume, cardiac output, and their variability). In this work, various electrode locations (12 different setups) have been tested for possible joint ECG & ICG data acquisition (using the same electrodes) and signal quality has been evaluated for every setup. It is shown that, while typically ICG is acquired over the whole thorax, a wrist-based joint acquisition of ECG & ICG signals can achieve acceptable signal quality and therefore can be considered in wearable sensing.
ICG(阻抗心动描记法)和 ECG(心电图)提供了关于心脏和整体心血管系统功能的重要指标。使用可穿戴设备同时测量 ICG 和 ECG 将提高健康监测的质量,因为 ICG 指向重要的血液动力学参数(如时间间隔、心搏量、心输出量及其可变性)。在这项工作中,已经测试了各种电极位置(12 种不同的设置),以实现可能的联合 ECG 和 ICG 数据采集(使用相同的电极),并评估了每种设置的信号质量。结果表明,虽然通常 ICG 是在整个胸部采集的,但基于手腕的 ECG 和 ICG 信号的联合采集可以获得可接受的信号质量,因此可以在可穿戴式传感中考虑。
