Building a Parameterized 4D Cardiac Model with Respiratory Motion from 2D MR Time Series (Universitat Politècnica de Catalunya, 2010-06)
Master thesis (pre-Bologna period)
Covenantee: Northeastern UniversityAtrial fibrillation (AF) is a growing problem in modern societies with an enormous impact in both short term quality of life and long term survival. A recently developed promising approach to cure AF uses radiofrequency ...
Effects of small conductance calcium activated potassium channels in atrial myocytes (IEEE Computer Society Conference Publishing Services (CPS), 2017)
Open AccessAmong the different potassium channels present in cardiac myocytes, the small conductance Ca2+ activated potassium channels (SK channels) are particular because they are affected by changes in intracellular calcium. The ...
Enabling atrial fibrillation detection using a weight scale (2016)
Restricted access - publisher's policyAtrial fibrillation (AF) is a cardiac arrhythmia characterized by a highly irregular heart rate. It is the most prevalent arrhythmia in the general population in the United States and most developed countries, and ...
Influence of fibrosis in the genesis of atrial fibrillation: a simulation study in human atrial tissue (Universitat Politècnica de Catalunya, 2021-07-13)
Open AccessA dual analysis pretends to associate spontaneous calcium release events (SCRE) as rapid arrhythmia triggers and, atrial fibrosis, as a proper substrate for the perpetuation of atrial fibrillation. This computational study ...
Influence of the tubular network on the characteristics of calcium transients in cardiac myocytes (Public Library of Science (PLOS), 2020-04-17)
Open AccessTransverse and axial tubules (TATS) are an essential ingredient of the excitation-contraction machinery that allow the effective coupling of L-type Calcium Channels (LCC) and ryanodine receptors (RyR2). They form a regular ...
Mathematical modeling of calcium handling dysfunctions leading to atrial fibrillation (Universitat Politècnica de Catalunya, 2017-10)
Open AccessThe aim of this master s thesis is to study the basic cardiac cellular electrophysiology in order to understand and examine the role of SK3 channels. Among the many channels present in an atrial myocyte, SK3 channels are ...
Modelling pathological effects in intracellular calcium dynamics leading to atrial fibrillation (Universitat Politècnica de Catalunya, 2020-07-23)
Open AccessThe heart beating is produced by the synchronization of the cardiac cells' contraction. A dysregulation in this mechanism may produce episodes of abnormal heart contraction. The origin of these abnormalities often lies at ...
On bio activity related signals from contactless electrode measurements (2016-02-01)
Open AccessIn a recent paper on a displacement current sensor for contactless detection of bio-activity related signals , it was stated that “A potential means for human presence detection…is via sensing…human biopotentials” ...
T-wave morphology restitution in chronic heart failure patient with atrial fibrillation (Institute of Electrical and Electronics Engineers (IEEE), 2018)
Open AccessChronic heart failure (CHF) represents one of the major public health problems that often end in sudden cardiac death (SCD). Atrial fibrillation (AF) is associated withan increased risk of SCD but nowadays there is no ...
Using high-resolution voltage maps to predict “redo” in the treatment of atrial fibrillation (AF) (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Open AccessThe aim of this work is to use biomarkers extracted from high-resolution voltage maps of atrial fibrillation (AF) patients in order to make predictions about future “redo” procedures. We collected maps of the left atrium ...
