La repolarización auricular y sus implicaciones clínicas

open access: yesRevista Colombiana de Cardiología, 2020
Resumen: La onda P en el electrocardiograma (ECG) representa exclusivamente la despolarización de las aurículas, puesto que, la repolarización auricular queda oculta en el QRS.

Mathematical tools for identifying the fetal response to physical exercise during pregnancy [PDF]

open access: yes, 2008
In the applied mathematics literature there exist a significant number of tools that can reveal the interaction between mother and fetus during rest and also during and after exercise.

Non-invasive acquisition of fetal ECG from the maternal xyphoid process: a feasibility study in pregnant sheep and a call for open data sets

open access: yes, 2018
Objective: The utility of fetal heart rate (FHR) monitoring can only be achieved with an acquisition sampling rate that preserves the underlying physiological information on the millisecond time scale (1000 Hz rather than 4 Hz).

Hospital Readmission After Traumatic Brain Injury Hospitalization in Community‐Dwelling Older Adults

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the risk of hospital readmission after an index hospitalization for TBI in older adults. Methods Using data from the Atherosclerosis Risk in Communities (ARIC) study, we used propensity score matching of individuals with an index TBI‐related hospitalization to individuals with (1) non‐TBI hospitalizations (primary analysis)

A Case of Severe Hyperkalemia Presenting with No Significant ECG Changes [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
An increase in serum potassium levels is followed by progressively severe electrophysiological derangements in cardiac impulse generation and conduction, which are reflected in the electrocardiogram (ECG).

Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]

open access: yes, 2004
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters.

Computer Aided ECG Analysis - State of the Art and Upcoming Challenges

open access: yes, 2013
In this paper we present current achievements in computer aided ECG analysis and their applicability in real world medical diagnosis process. Most of the current work is covering problems of removing noise, detecting heartbeats and rhythm-based analysis.

Feasibility and performance of a device for automatic self-detection of symptomatic acute coronary artery occlusion in outpatients with coronary artery disease : a multicentre observational study [PDF]

open access: yes, 2019
Background Time delay between onset of symptoms and seeking medical attention is a major determinant of mortality and morbidity in patients with acute coronary artery occlusion. Response time might be reduced by reliable self-detection.

Prognostic Implications of Sleep Architecture for Patients Admitted to the Intensive Care Unit With Status Epilepticus

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Status epilepticus (SE) is associated with significant mortality. Sleep architecture may reflect normal brain function. Impaired sleep architecture is associated with poorer outcomes in numerous conditions. Here we investigate the association of sleep architecture in continuous EEG (cEEG) with survival in SE.

Predictive ECG coding using linear time-invariant models [PDF]

open access: yesArchive of Oncology, 2004
Electrocardiogram (ECG) signal compression suffers of lack of standards for analogue-digital conversion. Results of this study have shown that 8 bits/sample, although frequently in use, does not satisfy quality criteria for medical doctors.
