Heart failure is a severe medical condition with an important worldwide incidence that occurs when the heart is unable to efficiently pump the patient's blood throughout the body. The monitoring of edema in the lower limbs is one of the most efficient ways to control the evolution of the condition. Impedance spectroscopy has been proposed as an efficient technique to monitor body volume in patients with heart failure. It is necessary to research new wearable devices for remote patient monitoring, which can be easily worn by patients in a continuous way. In this work, we design and implement new wearable textile electrodes for the monitoring of edema evolution in patients with heart failure. Impedance spectroscopy measurements were carried out in 5 healthy controls and 2 patients with heart failure using our wearable electrodes for 3 days. The results show the appropriateness of impedance spectroscopy and our wearable electrodes to monitor body volume evolution. Impedance spectroscopy is shown to be an efficient marker of the presence of edema in heart failure patients. Initial patient positive feedback was obtained for the use of the wearable device.
心力衰竭是一种严重的医学病症，在全球范围内发病率很高，当心脏无法有效地将患者的血液泵送到全身时，就会发生心力衰竭。监测下肢水肿是控制病情发展的最有效方法之一。阻抗谱已被提议作为监测心力衰竭患者体内容量的有效技术。有必要研究新的可穿戴设备来进行远程患者监测，这些设备可以让患者方便地连续佩戴。在这项工作中，我们设计并实现了新的可穿戴纺织电极，用于监测心力衰竭患者的水肿演变。使用我们的可穿戴电极对 5 名健康对照者和 2 名心力衰竭患者进行了 3 天的阻抗谱测量。结果表明，阻抗谱和我们的可穿戴电极非常适合监测体内容量的演变。阻抗谱被证明是心力衰竭患者水肿存在的有效标志物。患者对可穿戴设备的使用给予了初步的积极反馈。
