A practical method for calculating Lyapunov exponents from small data sets

Source: Physionet

Detecting the presence of chaos in a dynamical system is an important problem that is solved by measuring the largest Lyapunov exponent. Lyapunov exponents quantify the exponential divergence of initially close state-space trajectories and estimate …

ECG-Derived Respiration

Source: Physionet

The ECG-Derived Respiration (EDR) technique is an approach to obtain a respiration signal from an ECG.. It is based on the observation that the positions of ECG electrodes on the chest surface move relative to the heart, and transthoracic impedance …
