Capturing non-Gaussianity of RR interval distributions based on Gaussian scale mixture representation

The time interval between two consecutive R-peaks in an electrocardiography signal is called the RR interval (RRI), and its non-Gaussianity is a valuable marker for assessing cardiovascular disease risk. While RRI non-Gaussianity can be quantified by fitting probability distributions, the selection...
