2014 News

New Database added: CEBSDB

News from: Combined measurement of ECG, Breathing and Seismocardiograms v1.0.0.

Dec. 12, 2014

Combined measurement of ECG, Breathing, and Seismocardiograms DataBase, CEBSDB. A dataset of 60 records from 20 volunteers has been contributed to PhysioBank by Miguel Angel Garcia Gonzalez and Ariadna Argelagos Palou from the Universitat Politecnica de Catalunya. Each record contains two ECGs, a respiration, and a seismocardiogram signals. The database was designed to check if errors in RR series are influenced by breathing, and if there is a significant variability in RR series estimated from ECGs versus seismocardiograms.

New Software added to PhysioNet

Nov. 4, 2014

Two new software packages have been added to PhysioNet by Joachim Behar, Gari Clifford, and colleagues at the University of Oxford. FECGSyn is a new Foetal ECG Waveform Generator. The second package, the Random Search Toolbox, is a MATLAB toolbox for selecting model hyper-parameters via random search.

Upcoming events: Computing Cardiology 2014 and MIT Critical Data Marathon

July 30, 2014

Two upcoming events this September at MIT will be of interest to PhysioNet users. The first is the International Critical Care Data Mining Marathon, a weekend event (5-7 September 2014). The International Critical Care Data Mining Marathon will bring together teams of engineers and clinicians to develop tools and crowd-source knowledge in clinical data, with a hands-on data mining workshop using the MIMIC-II Database.

The second event is the 2014 Computing in Cardiology conference held from September 7-10 2014 at Cambridge, Massachusetts. Computing in Cardiology is an international scientific conference that has been held annually since 1974 and hosting PhysioNet Challenges since 2000. This conference provides a forum for scientists and professionals from the fields of medicine, physics, engineering and computer science to discuss their current research in topics pertaining to computing in clinical cardiology and cardiovascular physiology.

National Sleep Research Resource

April 4, 2014

PhysioNet users with an interest in sleep physiology now have access to the web site of the National Sleep Research Resource (NSRR), which hosts large annotated collections of EDF polysomnograms and related clinical data elements from well-characterized research cohorts and clinical trials. The first data set available includes over 8,000 studies from exams 1 and 2 of the Sleep Heart Health Study, with scheduled new data releases every quarter from additional data sets. NSRR also provides open-source software for viewing and analyzing these data.

Biometric Human Identification based on ECG

News from: ECG-ID Database v1.0.0.

March 6, 2014

The ECG-ID Database is a set of 310 ECGs from 90 volunteers, created and contributed to PhysioBank by Tatiana Lugovaya, who used the ECGs in her master's thesis. An excellent summary of this thesis, with a discussion of the challenges in using ECGs as biometrics, and a comparison of the author's methods and results with those of three previous studies, is also available.

ERP-based Brain-Computer Interface recordings

News from: ERP-based Brain-Computer Interface recordings v1.0.0.

March 4, 2014

This dataset, created and contributed by Luca Citi, Riccardo Poli, and Caterina Cinel, was generated as part of a study aimed at identifying the factors limiting the performance of brain-computer interfaces (BCIs) based on event-related potentials (ERPs), in order to improve the transfer rate and the usability of these interfaces. Twenty recordings of each of 10 participants include annotated 64-channel EEGs and 4-channel EOGs, generated while the participants focused on specified target characters displayed by a traditional matrix speller.

Motion Artifact Contaminated fNIRS and EEG Data

News from: Motion Artifact Contaminated fNIRS and EEG Data v1.0.0.

March 3, 2014

This data collection, contributed to PhysioNet by Kevin Sweeney and colleagues at the National University of Ireland in Maynooth, contains examples of functional near-infrared spectroscopy (fNIRS) and electroencephalogram (EEG) recordings that have been created for evaluating artifact removal methods. In each such recording, one or two pairs of similar physiological signals have been acquired from transducers in close proximity. One signal of each pair is contaminated by motion artifact, documented in each case by simultaneously recorded outputs of 3-axis accelerometers affixed to each transducer.
