Detection of obstructive sleep apnea can be performed through heart rate variability analysis, since fluctuations of oxygen saturation in blood cause variations in the heart rate. Such variations in heart rate can be assessed by means of time-frequency analysis implemented with time-frequency distributions belonging to Cohen's class. In this work, dynamic features are extracted from time frequency...
The aim of this study is to detect the ischemia-induced changes of heart rate variability (HRV) indices based on time-frequency analysis and to investigate the patterns of change when the duration of ischemia is concerned.
The cardiovascular diseases are the main cause of mortality in the industrialized world. The efforts to improve the diagnosis and the therapy in our days are highly developed. A noninvasive technique is the analysis of HRV (Heart Rate Variability) often from electrocardiography records (ECG) of 24 hours. HRV is the measurement of the interval between R peaks of two consecutive QRS complexes (RR intervals)...
