Assessment of the depth of anesthesia based on symbolic dynamics of the EEG
(2010)
Conference lecture
Open AccessMethodologies based on symbolic dynamics have successfully demonstrated to reflect the nonlinear behavior of biological signals. In the present study, symbolic dynamics was applied to the electroencephalogram (EEG) in ... -
Caracterización de pacientes con diferentes niveles de riesgo cardiovascular mediante diagramas de Poincaré
(Editorial Universitat Politècnica de València, 2016)
Conference lecture
Open AccessEn este trabajo se propone caracterizar la dinámica no-lineal de los sistemas cardíaco, vascular y respiratorio a partir de los diagramas de Poincaré. Se han analizado 46 pacientes con cardiomiopatía isquémica (ICM) o ... -
Caracterización de pacientes isquémicos y dilatados a partir de las señales ECG y de presión sanguínea

Characterization and classification of patients with different levels of cardiac death risk by using Poincaré plot analysis
(2017)
Conference lecture
Open AccessCardiac death risk is still a big problem by an important part of the population, especially in elderly patients. In this study, we propose to characterize and analyze the cardiovascular and cardiorespiratory systems using ... -
Characterization of blood pressure signal considering low and high risk stratification in cardiomyopathy patients
(2013)
Conference report
Restricted access - publisher's policyIschemic and dilated cardiomyopathy are associated with disorders of myocardium. Using the blood pressure (BP) signal and the values of the ventricular ejection fraction, we obtained parameters for stratifying cardiomyopathy ... -
Characterization of patients with different ventricular ejection fractions using blood pressure signal analysis
(2013)
Conference report
Restricted access - publisher's policyIschemic and dilated cardiomyopathy are associated with disorders of myocardium. Using the blood pressure (BP) signal and the values of the ventricular ejection fraction, we obtained parameters for stratifying cardiomyopathy ... -
Cuantificación de la recurrencia en el estudio de la variabilidad del ritmo cardiaco y la duración del ciclo respiratorio en pacientes en proceso de extubación
(2011)
Conference report
Open AccessEl sistema nervioso autónomo regula el comportamiento de los sistemas cardiaco y respiratorio. Su evaluación durante la retirada de la ventilación mecánica puede proporcionar información sobre el comportamiento ... -
Detrended fluctuation analysis of heart rate by means of symbolic series
(2010)
Conference report
Open AccessDetrended fluctuation analysis (DFA) has been shown to be a useful tool for diagnosis of patients with cardiac diseases. The scaling exponents obtained with DFA are an indicator of power-law correlations in signal ... -
Diagnosis of ischemic heart disease with cardiogoniometry – Linear discriminant analysis versus support vector machines
(2008)
Conference report
Restricted access - publisher's policyThe Ischemic Heart Disease (IHD) is characterized by an insufficient supply with blood of the myocardium usually caused by an artherosclerotic disease of the coronary arteries (coronary artery disease CAD). The IHD and its ... -
Effect of acute myocardial ischemia on different high-frequency bandwidths and temporal regions of the QRS
(IEEE, 2011)
Conference lecture
Restricted access - publisher's policyThe purpose of this study was to describe the changes in high-frequency QRS (HF-QRS) components due to myocardial ischemia provoked by prolonged artery occlusion during percutaneous coronary interventions (PCI). ... -
Evaluation of acceleration and deceleration cardiac processes using phase-rectified signal averaging in healthy and idiopathic dilated cardiomyopathy subjects
(2015-02-01)
Article
Open AccessThe aim of the present study was to investigate the suitability of the Phase-Rectified Signal Averaging (PRSA) method for improved risk prediction in cardiac patients. Moreover, this technique, which separately evaluates ... -
Extraction of the respiration signal from the electrocardiogram
(2015)
Conference report

Heart rate variability characterized by refined multiscale entropy applied to cardiac death in ischemic cardiomyopathy patients
(2010)
Conference lecture
Restricted access - publisher's policyIn this work, Refined Multiscale Entropy (RMSE) was applied to characterize risk of cardiac death in ischemic cardiomyopathy patients, analyzing heart rate variability (HRV) by means of RR series during daytime and ... -
Higuchi's fractal complexity of RR and QT interval series during transient myocardial ischemia
(2013)
Conference report
Restricted access - publisher's policyMyocardial ischemia may lead to significant changes in autonomic control of heart rate (HR) affecting its variability and alter beat-to-beat ventricular repolarization periods. We hypothesized that transient myocardial ... -
Influence of respiration in the very low frequency modulation of QRS slopes and heart rate variability in cardiomyopathy patients
(2013)
Conference lecture
Restricted access - publisher's policyThis work investigates the very low frequency (VLF) modulation of QRS slopes and heart rate variability (HRV). Electrocardiogram (ECG) and respiratory flow signal were acquired from patients with dilated cardiomyopathy and ... -

Segmented Symbolic Dynamics for Risk Stratification in Patients with Ischemic Heart Failure, Cardiovascular Engineering and Technology
(Springer, 2010-12-30)
Article
Restricted access - publisher's policyChronic heart failure (CHF) is recognized as major and escalating public health problem. Approximately 69% of CHF patients suffer from cardiac death within 5 years after the initial diagnosis. Until now, no generally accepted ...
