Non-contact ECG System for Unobtrusive Long-Term Monitoring

描述（由申请人提供）：拟议研究的目的是展示一种用于长期监测心电图（ECG）的创新无创系统。在许多患者中，心律失常和心电图改变是无症状的或短暂的，因此可能未被发现或诊断。然而，使用当前技术的长期心电图研究具有侵入性，用户依从性低，并且通常仅限于使用植入式设备的高危患者。在提出的系统中，新型非接触式生物电极传感器集成到可以放置在椅子或床上的垫中。该制度的主要特点是它很少或根本不需要主体的服从。该程序将演示系统的信号质量，并通过比较pad的测量结果与传统ECG电极的测量结果来量化系统的性能。由于先前缺乏合适的技术，在家庭环境中延长心电图监测所提供的新可能性尚未被量化，甚至在初步水平上进行评估。这项研究将为长期心脏监测提供一种新的能力，可用于监测患者，以便早期发现心脏病或跟踪患者心脏病的进展。公共卫生相关性：该项目的目的是生产一种具有嵌入式传感技术的垫子，可以产生心电图（ECG）数据。这个垫子可以让受试者坐在椅子上或躺在床上，同时进行心脏监测。这将提供比当前技术允许的更舒适和更长期的测量，并适用于心律失常和充血性心力衰竭患者的监测。

DESCRIPTION (provided by applicant): The aim of the proposed research is to demonstrate an innovative noninvasive system for long-term monitoring of the electrocardiogram (ECG). In many patients, arrhythmias and changes in the ECG are asymptomatic or transient, and therefore may remain undetected or undiagnosed. However, long-term ECG studies using current technology is invasive, suffers from low user compliance, and is typically confined to high at-risk patients using implantable devices. In the proposed system, novel non-contact bioelectrode sensors are integrated into a pad that can be placed on a chair or bed. The primary feature of the system is that it requires little or no compliance from the subject. This program will demonstrate the system's signal quality and quantify the performance of the system by comparing measurements from the pad with measurements from conventional ECG electrodes. The new possibilities afforded by prolonged ECG monitoring in a home setting are yet to be quantified or even assessed at a preliminary level owing to the prior lack of suitable technology. This research will provide a new capability for long term cardiac monitoring that can be used for monitoring patients for the early detection of cardiac disease or to track the progression of heart disease in sick patients. PUBLIC HEALTH RELEVANCE: The aim of this program is to produce a pad with embedded sensing technology that can produce electrocardiogram (ECG) data. This pad would allow subjects to sit in a chair or lie on a bed while heart monitoring is being conducted. This would provide a more comfortable and longer-term measurement than current technology allows, and have applicability for monitoring of arrhythmia and congestive heart failure patients.
