FAW: Arrhythmia Detection for Implantable Devices

本研究的目的是设计和开发应用于心内导联的信号分析和形态分析的新技术。在过去的两年里，实验室设计了六个新的计算效率高的检测方案，并通过短期的初步研究确定了可行性。需要进一步的工作来测试在存在正常(生理)心率加速的情况下检测方案的稳健性。此外，还将应用形态运算符(波形分析的一种非线性方法)来解决由药物的引入或移除引起的波形细微变化的问题。另一种新的方法，时频分析，也将被检查，以评估其性能与标准的时域方法。在所有情况下，目标都是在不损失灵敏度的情况下提高检测的特异性。

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.
