This study introduces a novel signal analysis technique derived from nonlinear dynamical systems theory. It converts signals into geometrical trajectories to detect and quantify electrical alternans.

Area of Science:

  • Nonlinear dynamical systems theory
  • Signal analysis
  • Biomedical engineering

Background:

  • Electrical alternans are a significant indicator of cardiac instability.
  • Traditional signal analysis methods may not fully capture the complex dynamics of electrical alternans.

Purpose of the Study:

  • To introduce and discuss a novel signal analysis technique for detecting and quantifying electrical alternans.
  • To explore the application of nonlinear dynamical systems theory to biomedical signal processing.

Main Methods:

  • Reconstruction of a state space from signal data.
  • Representation of the signal as a geometrical trajectory within the state space.
  • Application of dynamical systems concepts to analyze trajectory properties.
