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.

描述（由申请人提供）：拟议研究的目的是证明一种创新的无创系统，用于对心电图（ECG）的长期监测。在许多患者中，心律不齐和心电图的变化是无症状或短暂的，因此可能仍未被发现或未被诊断。但是，使用当前技术的长期心电图研究具有侵入性，符合用户的依从性低，并且通常仅限于使用可植入设备的高危患者。在拟议的系统中，新型的非接触性生物电极传感器集成到可以放在椅子或床上的垫子中。该系统的主要特征是它几乎不需要该主题的合规性。该程序将通过将PAD的测量结果与常规的ECG电极进行比较，证明系统的信号质量并量化系统的性能。由于先前缺乏合适的技术，因此在家庭环境中长时间的心电图监测所提供的新可能性尚待量化甚至是初步评估。这项研究将为长期心脏监测提供新的能力，可用于监测患者早期发现心脏病或跟踪患病患者心脏病的进展。公共卫生相关性：该计划的目的是生产具有嵌入式感应技术的垫，可以产生心电图（ECG）数据。该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，更长期的测量，并适用于监测心律不齐和充血性心力衰竭患者。
