TLDR
The results obtained indicate that this computer aided classification system can be used as an additional diagnostic tool to effectively differentiate between the normal subjects and HTN and CAD affected patients.Abstract:
The hypertension (HTN) and coronary artery disease (CAD) are the major cardiovascular diseases existing globally. In the present work, the heart rate variability (HRV) of normal (NOR) subjects, HTN and CAD patients has been compared using linear and nonlinear features with different classifiers. The proposed work considers five minutes recordings of electrocardiogram (ECG) for processing of consecutive heartbeat (RR) interval tachogram, extracting the features from short term HRV data by linear and nonlinear methods, comparative analysis of HRV features and classification of controlled subjects from diseased patients like HTN and CAD using various classifiers. The analysis results indicate that all the three categories of data have distinguishable differences in entire set of features and classification results indicate that support vector machine (SVM) classifier achieves a classification accuracy of 96.67% and individual sensitivity values of 90%, 100% and 100% for NOR, HTN, and CAD classes respectively. The results obtained using the proposed methodology indicate that this computer aided classification system can be used as an additional diagnostic tool to effectively differentiate between the normal subjects and HTN and CAD affected patients.read more

TL;DR: The findings demonstrate that AI-based techniques have been increasingly applied for the detection of CAD since 2008 and demonstrate that the attribution of the relative importance of ML features for CAD diagnosis is different among countries.

Physiological time-series analysis using approximate entropy and sample entropy
TL;DR: A new and related complexity measure is developed, sample entropy (SampEn), and a comparison of ApEn and SampEn is compared by using them to analyze sets of random numbers with known probabilistic character, finding SampEn agreed with theory much more closely than ApEn over a broad range of conditions.

Approximate entropy as a measure of system complexity.
TL;DR: Analysis of a recently developed family of formulas and statistics, approximate entropy (ApEn), suggests that ApEn can classify complex systems, given at least 1000 data values in diverse settings that include both deterministic chaotic and stochastic processes.

TL;DR: HR variability remained a significant predictor of mortality after adjusting for clinical, demographic, other Holter features and ejection fraction, and a hypothesis to explain this finding is that decreased HR variability correlates with increased sympathetic or decreased vagal tone, which may predispose to ventricular fibrillation.

Probabilistic neural networks
TL;DR: A probabilistic neural network that can compute nonlinear decision boundaries which approach the Bayes optimal is formed, and a fourlayer neural network of the type proposed can map any input pattern to any number of classifications.
