Abstract：
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.
摘要：
心力衰竭是一种严重的医学疾病，具有重要的全球发病率，当心脏无法有效地将患者的血液泵到全身时发生。监测下肢水肿是控制病情发展的最有效方法之一。阻抗谱已被提出作为监测心力衰竭患者身体体积的有效技术。有必要研究用于远程患者监护的新型可穿戴设备,患者可以轻松地连续佩戴。在这项工作中,我们设计并实施了新型可穿戴纺织电极,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在5名健康对照和2名心力衰竭患者中进行阻抗谱测量3天。结果表明阻抗谱和我们的可穿戴电极监测身体体积演变的适当性。阻抗谱被证明是心力衰竭患者中水肿存在的有效标记。对于可穿戴设备的使用,获得初始患者正反馈。
