New Database Added: SHAREEDB
19 May, 2015 06:00:00 PM EST

Smart Health for Assessing the Risk of Events via ECG (SHAREE database). The SHAREE database was developed in order to investigate the possibility of identifying hypertensive subjects at higher risk to develop vascular events based on Heart Rate Variability analysis. The database was created by Paolo Melillo, Raffaele Izzo, Ada Orrico, Paolo Scala, Marcella Attanasio, Marco Mirra, Nicola De Luca, and Leandro Pecchia as part of the “Smart Health and Artificial intelligence for Risk Estimation” (SHARE) project, which seeks ways to prevent cardiovascular events and falls in people over 65.

New Database Added: EHGDB
9 May, 2015 12:00:00 AM EST

Icelandic 16-electrode Electrohysterogram DataBase ( EHGDB). A new dataset of 122 16-electrode EHG recordings performed on 45 pregnant Icelandic women has been published in PhysioBank. The data was contributed by Ásgeir Alexandersson, who performed the recordings at Akureyri Primary Health Care Centre, Akureyri Hospital and Landspitali University Hospital. A detailed description of the database has been published in Nature's new journal Scientific Data 2, Article number: 150017 (2015).

PhysioNet/CinC Challenge 2015
15 February, 2015 12:00:00 AM EST

The PhysioNet/Computing in Cardiology Challenge 2015 is now open. This year's challenge is 'Reducing False Arrhythmia Alarms in the ICU'. False alarms in the ICU can lead to a disruption of care, impacting both the patient and the clinical staff through noise disturbances, desensitization to warnings and slowing of response times, leading to decreased quality of care. To address this issue, competitors are challenged to devise a method of processing all the available data to reduce false alarms with minimal or no effect on true (vital) alarms.

New software packages added to PhysioToolkit!
31 January, 2015 12:00:00 PM EDT

Two new software packages have been added to PhysioToolkit! The first package, D3Maps, is a tool for visualizing the behavior of complex systems by means of the dynamical density delay mapping technique. This package was developed at the Wyss Institute by A. Burykin, L. Citi, M.D. Costa and A.L. Goldberger. The second software package, Multiscale Multifractal Analysis, is a time series analysis method designed to describe scaling properties of fluctuations within a signal. The software package was contributed by Jan Gierałtowski from Warsaw University of Technology.

PhysioNet approved as repository for Nature's Scientific Data!
23 January 2015 12:00:00 AM EDT

PhysioNet is pleased to announce that we are now an officially recommended repository for the journal Scientific Data (SciData). SciData is an open-access, peer-reviewed publication from the Nature Publishing Group focusing on scientifically valuable research datasets. SciData's primary article-type, the Data Descriptor, is designed to make your data more discoverable, interpretable and reusable. Users who have contributed data to PhysioNet are now invited to submit their unpublished data as a Data Descriptor to Scientific Data! Pre-submission enquires are welcome at

New Database Added: CEBSDB
12 December 2014 12:00:00 AM EDT

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 Softwares added to PhysioToolkit
4 November 2014 9:00:00 EDT

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

Computing Cardiology 2014/Critical Data Marathon
30 July 2014 10:00:00 EDT

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.
