The effect of respiration-induced heart movements on the ECG
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1989-06-01)
Article
Accés obertWe present a model describing the rotation of the cardiac vector as a possible mechanism resulting in the presence of respiratory information in the ECG. The way in which this information is revealed is analyzed and the ... -
The feasibility of transoesophageal bioimpedance measurements for the detection of heart graft rejection
(IOP PUBLISHING LTD, 2011-07)
Article
Accés restringit per política de l'editorialPrevious studies demonstrate that it is possible to evaluate a heart graft rejection condition using a bioimpedance technique by means of an intracavitary catheter. We propose to use a less invasive technique consisting ... -
The help4mood wearable sensor network for inconspicuous activity measurement
(2013-08)
Article
Accés restringit per política de l'editorialThe Help4Mood EU FP7 project (H4M) [1] proposes to significantly advance the state-ofthe-art in computerized support for people with Major Depression by monitoring mood, physical activity and voice characteristics while ... -
Total body water changes using segmental bioimpedance in healthy population with similar anthropometry
(Springer Verlag, 2009)
Comunicació de congrés
Accés obertElectrical bioimpedance was measured in 7 body segments, and also with the standard right-side method, using 11 electrodes at 6 different frequencies in 8 healthy male subjects with similar anthropometry. Our objective was ... -
Transmural versus non-transmural in situ electrical impedance spectrum for healthy, ischemic, and healed myocardium
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2004-08-31)
Article
Accés obertElectrical properties of myocardial tissue are anisotropic due to the complex structure of the myocardial fiber orientation and the distribution of gap junctions. For this reason, measured myocardial impedance may differ ... -
Transoesophageal detection of heart graft rejection by electrical impedance: using Finite Element Method simulations
(2010)
Text en actes de congrés
Accés obertPrevious studies have shown that it is possible to evaluate heart graft rejection level using a bioimpedance technique by means of an intracavitary catheter. However, this technique does not present relevant advantages ... -
Transoesophageal electrical bioimpedance measurements of the heart in humans
(Springer Verlag, 2009-09)
Text en actes de congrés
Accés restringit per política de l'editorialPrevious studies have proved that posttransplant cardiac rejection is associated with changes in endomyocardial electrical impedance in humans. The aim of this study is to develop a safe transoesophageal system able to ... -
Ultra-high input impedance buffer for dry or capacitive electrodes: design and characterization for industry
(Institute of Electrical and Electronics Engineers (IEEE), 2023-07-04)
Article
Accés obertA large number of health and wellness applications wish to monitor electrocardiogram signal (ECG) in the least intrusive way possible. The use of dry textile electrodes with high input impedance bio-amplifiers is a common ... -
Usefulness of bioelectrical impedance analysis for monitoring patients with refractory ascites
(2019-01-01)
Article
Accés obertBackground: bioelectrical impedance analysis is a technique for the determination of the hydropic component. The hydropic component, determined by blood volume, could be a reflection of the hemodynamic situation. This ... -
Using temporal electrical impedance spectroscopy measures to differentiate lung pathologies with the 3-electrode method
(2022)
Comunicació de congrés
Accés obertMinimally invasive lung bioimpedance measurements could serve in the future diagnosis of lung pathologies complementing biopsies and imaging techniques. Through the electrical impedance spectroscopy (EIS) technique using ...
