In this episode, it is explored that the possibility that ECG records belong to class of multifractal process for which a a lot of scaling exponents are necessary to characterize their scaling forms. There are many recent studies which confirmed that the healthy heartbeat shows regular cardiac beat based on Homeostasis principals since physiologically, our physique system tries to reduce soul rate variability (HRV). We use the BIDMC Congestive Heart Failure database containing long term ECG recordings from 11 brothers, aged 22 to 71, and 4 wives, aged 54 to 63 with harsh congestive heart failure and the MIT-BIH Arrhythmia database that holds 48 half-hour excerpts of two-channel ambulatory ECG records, obtained from 47 cases studied by the BIH Arrhythmia Laboratory middle from two points 1975 and 1979. We compare these two chronic soul diseases with the control folk in the MIT-BIH Normal Sinus Rhythm database that includes 18 long-term ECG records of 5 men, aged 26 to 45, and 13 mothers, aged 20 to 50 without important arrhythmia. The vibration analysis in the way that power ghostly densities (PSD) analysis has been acted for differentiating the time order. Multifractal spectrum analysis has judged the multifractal dynamics of pulse interval signals to distinguish between subjects with severe heart attack and normal signals with arrhythmia. The fractal complicatedness of each heart beat is determined utilizing the Higuchi algorithm, and the signals are therefore contrasted over various opportunity intervals [1]. According to our analysis, when multifractal study and scaling exponent were secondhand as a classifier, the three classes were well separated. In addition, multifractal study revealed that we have a narrow range of exponents for arrhythmia and congestive heart failure issues and as a result, a clear loss of multifractality for bureaucracy. We continue the analysis of pulse interval time succession by estimating the capacity law scaling exponents for active subjects and compare bureaucracy with scaling exponents of victims with heart attack and arrhythmia. Then we apply multifractal analysis to study the multifractal makeup and complex dynamics of these three groups of signals. Our findings support a comprehensive framework for demonstrative and classifying different subjects with cardiac disease to a degree arrhythmia and congestive heart failure and differentiate bureaucracy with normal crowd without heart disease that is crucial in judgment the best diagnostic and ruling strategy in fight against chronic myocardial infarction.
