The heart integrates neuroregulatory messages into specific bands of frequency, such that the overall amplitude spectrum of the cardiac output reflects the variations of the autonomic nervous system. This modulatory mechanism seems to be well adjusted to the unpredictability of the cardiac demand, maintaining a proper cardiac regulation. A longstanding(More)
Congestive heart failure (CHF) is a cardiac disease associated with the decreasing capacity of the cardiac output. It has been shown that the CHF is the main cause of the cardiac death around the world. Some works proposed to discriminate CHF subjects from healthy subjects using either electrocardiogram (ECG) or heart rate variability (HRV) from long-term(More)
Congestive heart failure (CHF) is a cardiac disease associated with the decreases in cardiac output. As a measure to predict sudden death, we propose a framework for discriminating CHF subjects from normal sinus rhythm (NSR). This framework relies on matching pursuit decomposition to derive a set of features, which are tested in a hybrid genetic algorithm(More)
