Analysis of QRS loop in the vectorcardiogram of patients with Chagas' disease
(2010)
Conference report
Open AccessIn the present work, we have studied the QRS loop in the Vectorcardiogram (VCG) of 95 chronic chagasic patients classified in different groups (I, II and III) according to their degree of myocardial damage. For comparison, ... -
An invasive and a noninvasive approach for the automatic differentiation of obstructive and central hypopneas
(2010-04-15)
Article
Open AccessThe automatic differentiation of obstructive and central respiratory events is a major challenge in the diagnosis of sleep-disordered breathing. Esophageal pressure (Pes) measurement is the gold-standard method to ... -
Assessment of inspiratory muscle activation using surface diaphragm mechanomyography and crural diaphragm electromyography
(2018)
Conference report
Restricted access - publisher's policyThe relationship between surface diaphragm mechanomyography (sMMGdi), as a noninvasive measure of inspiratory muscle mechanical activation, and crural diaphragm electromyography (oesEMGdi), as the invasive gold standard ... -
Assessment of respiratory flow cycle morphology in patients with chronic heart failure
(2017-02-01)
Article
Open AccessBreathing pattern as periodic breathing (PB) in chronic heart failure (CHF) is associated with poor prognosis and high mortality risk. This work investigates the significance of a number of time domain parameters for ... -
Assessment of respiratory muscle activity with surface electromyographic signals acquired by concentric ring electrodes
(2018)
Conference lecture
Restricted access - publisher's policyThe assessment of respiratory muscle activity by surface electromyography (sEMG) is a promising noninvasive technique for the diagnosis and monitoring of chronic obstructive pulmonary disease. The diaphragm is the ... -
Automatic differentiation of normal and continuous adventitious respiratory sounds using ensemble empirical mode decomposition and instantaneous frequency
(2016-03-01)
Article
Open AccessDifferentiating normal from adventitious respiratory sounds (RS) is a major challenge in the diagnosis of pulmonary diseases. Particularly, continuous adventitious sounds (CAS) are of clinical interest because they reflect ... -
Automatic differentiation of obstructive and central hypopneas with esophageal pressure measurement during sleep
(2009)
Conference report
Open AccessThe differentiation between obstructive and central respiratory events is one of the most recurrent tasks in the diagnosis of sleep disordered breathing. Esophageal pressure measurement is the gold-standard method to ... -
Automatic non-invasive differentiation of obstructive and central hypopneas with nasal airflow compared to esophageal pressure
(2010)
Conference report
Open AccessThe differentiation of obstructive and central respiratory events is a major challenge in the diagnosis of sleep disordered breathing. Esophageal pressure (Pes) measurement is the gold-standard method to identify these ... -
Breathing pattern characterization in chronic heart failure patients using the respiratory flow signal
(2010-07-08)
Article
Restricted access - publisher's policyThis study proposes a method for the characterization of respiratory patterns in chronic heart failure (CHF) patients with periodic breathing (PB) and nonperiodic breathing (nPB), using the flow signal. Autoregressive ... -
Cancellation of cardiac interference in diaphragm EMG signals using an estimate of ECG reference signal
(2014)
Conference report
Open AccessThe analysis of the electromyographic signal of the diaphragm muscle (EMGdi) can provide important information in order to evaluate the respiratory muscular function. However, EMGdi signals are usually contaminated by the ... -

Restricted access - publisher's policyA recursive least square (RLS) adaptive filtering algorithm for reduction of cardiac interference in diaphragmatic mecanomyographic (MMGdi) signals is addressed in this paper. MMGdi signals were acquired with a capacitive ... -
Cardiorespiratory phase synchronization in OSA subjects during wake and sleep states
(2015)
Conference report
Restricted access - publisher's policyCardiorespiratory Phase Synchronization (CRPS) is a manifestation of coupling between cardiac and respiratory systems complementary to Respiratory Sinus Arrhythmia. In this work, we investigated CRPS during wake and sleep ... -
Characterization of laplacian surface electromyographic signals during isometric contraction in biceps brachii
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference report
Restricted access - publisher's policySurface electromyography (sEMG) is a noninvasive technique for monitoring the electrical activity produced by the muscles. Usually, sEMG is performed by carrying out monopolar or bipolar recordings by means of conventional ... -
