The complexity of electrocardiogram (ECG) signal may reflect the physiological function and healthy status of the heart … and area, to characterize the nonlinear complexity of ECG signal. These indicators express the nonlinear superposition of … in exploring the complexity of this time series. We then studied the ECG mass exponent spectra taken from the cohorts of …

(ECG) signals taken from healthy adult subjects have been found to characterize multifractality. In this paper, multiscale … heart electrical activities. We then investigated the multifractal singularity spectrum area of synchronous 12-lead ECG … statistical results suggest the arithmetical mean value of the area of the 12 leads ECG signals is obviously small for myocardial …

We investigate ECG recordings of healthy subjects (H subjects) and those with heart failure (HF subjects) based on a … new measure derived from the shape of the ECG signal during each heart beat. From this measure we construct sequences …
