<h4>Aims</h4>The need for a readily available, inexpensive, non-invasive method for improved risk stratification of heart failure (HF) patients is paramount. Prior studies have proposed that distinct fluctuation patterns underlying the variability of physiological signals have unique prognostic value. We tested this hypothesis in an extensively phenotyped cohort of HF patients using EntropyX<sub>QT</sub>, a novel non-linear measure of cardiac repolarization dynamics.<h4>Methods and results</h4>I ...[more]
