A review of signals used in sleep analysis.
Aoife Roebuck,Violeta Monasterio,Violeta Monasterio,Elnaz Gederi,Maxim Osipov,Joachim Behar,Atul Malhotra,Thomas Penzel,Gari D. Clifford +8 more
TL;DR: Both univariate and data fusion approaches (exploiting the diverse characteristics of the primary recorded signals) approaches are discussed, together with a comparison of automated methods for analysing sleep.
Sudden cardiac death and pump failure death prediction in chronic heart failure by combining ECG and clinical markers in an integrated risk model
Julia Ramirez,Michele Orini,Ana Mincholé,Violeta Monasterio,Iwona Cygankiewicz,Antonio Bayés de Luna,Juan Pablo Martinez,Pablo Laguna,Esther Pueyo +8 more
TL;DR: The inclusion of ECG markers capturing complementary pro-arrhythmic and pump failure mechanisms into risk models based only on standard clinical variables substantially improves prediction of SCD and PFD in CHF patients.
Comparative Evaluation of Methodologies for T-Wave Alternans Mapping in Electrograms
Michele Orini,Ben Hanson,Violeta Monasterio,Juan Pablo Martinez,Martin Hayward,Peter Taggart,Pier D. Lambiase +6 more
TL;DR: Application on epicardial mapping of the in vivo human heart shows that EGM-TWA has heterogeneous spatio-temporal distribution, while LLR was the most robust, providing better detection-rates in noisy conditions.

A Nonparametric Surrogate-Based Test of Significance for T-Wave Alternans Detection
TL;DR: The proposed surrogate method for rejecting noise was compared to the standard noise-rejection methods used with the spectral method and the modified moving average techniques, and resulted in a larger margin of separability between patient populations than when the SM or MMA were applied to the same data.
Prognostic value of average T-wave alternans and QT variability for cardiac events in MADIT-II patients.
Violeta Monasterio,Juan Pablo Martinez,Pablo Laguna,Scott McNitt,Slava Polonsky,Arthur J. Moss,Mark C. Haigney,Wojciech Zareba,Jean-Philippe Couderc +8 more
TL;DR: Increased TWA and QTV are independent predictors of appropriate ICD therapy in MADIT-II patients with elevated heart rate at baseline, and neither QTV nor TWA predicted SCD.
