FAW: Arrhythmia Detection for Implantable Devices

本研究的目标是设计和开发新的技术 信号分析和形态学分析应用于 心内电极导线 在过去的两年里，六个新的 已经设计了计算上有效的检测方案， 实验室和可行性已经建立了初步的 在短段落中学习。 需要进一步的工作来测试 在正常情况下检测方案的鲁棒性 （生理学上的）心跳加速。 此外，本发明还提供了一种方法， 形态算子（一种非线性分析方法， 波形）将被应用于解决微妙的问题， 由于引入或移除 药剂。 另一种新的方法，时间-频率 分析，也将审查，以评估其性能与 标准时域方法。 在所有情况下，目标都是 增加检测特异性而不损失灵敏度。

The goal of this research is to design and develop new techniques of signal analysis and morphological analysis applied to intracardiac leads. Over the past two years, six new computationally efficient detection schemes have been designed in the laboratory and feasibility has been established by preliminary studies in short passages. Further work is necessary to test the robustness of the detection schemes in the presence of normal (physiologic) acceleration of heart rate. In addition, morphological operators (a non-linear method of analysis of waveforms) will be applied to address the problem of subtle waveform changes caused by the introduction or removal of pharmaceutic agents. Another new approach, time-frequency analysis, will also be examined to assess its performance versus standard time-domain methods. In all cases, the goal is to increase specificity of detection without loss of sensitivity.
