In this paper, we introduced two novel parameters, the curvature and area of multifractal mass exponent spectrum. In addition, using the multiscale analysis method, we studied the mass exponent spectra of ECG signals taken from the cohorts of healthy, ischemia and myocardial infarction (MI) sufferer with different sampling frequencies and data points, expecting to acquire some valuable nonlinear eigenvalues...
Life is one of the most complex nonlinear systems and heart is the core of this lifecycle system. In this paper, multiscale analysis method was introduced to find the most effective parameters for expressing the complex nonlinear dynamic characteristics of heart electrical activities. After determining the appropriate scale factor, we investigated the multifractal singularity spectrum area of synchronous...
