新落成的复杂生理信号研究资源是在美国国立卫生研究院国家研究资源中心的主持下创建的，旨在促进心血管和其他复杂生物医学信号研究的当前研究和新调查。资源有3个相互依赖的组件。PhysioBank是一个大型且不断增长的档案库，其中包含生理信号和相关数据的良好特征数字记录，供生物医学研究界使用。它目前包括多参数心肺，神经和其他生物医学信号的数据库，这些信号来自健康受试者和患有各种具有重大公共卫生影响的疾病的患者，包括危及生命的心律失常，充血性心力衰竭，睡眠呼吸暂停，神经系统疾病和衰老。PhysioToolkit是用于生理信号处理和分析的开源软件库，使用经典技术和基于统计物理学和非线性动力学的新方法检测生理学上重要的事件，信号的交互式显示和表征，新数据库的创建，生理信号和其他信号的模拟，分析方法的定量评估和比较，和非平稳过程的分析。PhysioNet是一个在线论坛，用于传播和交换记录的生物医学信号以及用于分析这些信号的开源软件。它为数据的合作分析和评估提出的新算法提供了便利。除了通过万维网（http：//www.example.com）提供免费的PhysioBank数据和PhysioToolkit软件的电子存取之外，PhysioNet还通过联机教程提供服务和培训，以帮助具有不同专业知识水平的用户。www.physionet.org
The newly inaugurated Research Resource for Complex Physiologic Signals, which was created under the auspices of the National Center for Research Resources of the National Institutes of Health, is intended to stimulate current research and new investigations in the study of cardiovascular and other complex biomedical signals. The resource has 3 interdependent components. PhysioBank is a large and growing archive of well-characterized digital recordings of physiological signals and related data for use by the biomedical research community. It currently includes databases of multiparameter cardiopulmonary, neural, and other biomedical signals from healthy subjects and from patients with a variety of conditions with major public health implications, including life-threatening arrhythmias,,congestive heart failure, sleep apnea, neurological disorders, and aging. PhysioToolkit is a library of open-source software for physiological signal processing and analysis, the detection of physiologically significant events using both classic techniques and novel methods based on statistical physics and nonlinear dynamics, the interactive display and characterization of signals, the creation of new databases, the simulation of physiological and other signals, the quantitative evaluation and comparison of analysis methods, and the analysis of nonstationary processes. PhysioNet is an on-line forum for the dissemination and exchange of recorded biomedical signals and open-source software for analyzing them. It provides facilities for the cooperative analysis of data and the evaluation of proposed new algorithms. In addition to providing free electronic access to PhysioBank data and PhysioToolkit software via the World Wide Web (http://www.physionet.org), PhysioNet offers services and training via on-line tutorials to assist users with varying levels of expertise.
