PhysioNet is one of four NIH-supported initiatives highlighted in a
recent White House blog entry
("Big
Data is a Big Deal for Biomedical Research") about accelerating
the pace of discovery through the use of Big Data. (The others are
the Human Connectome Project,
the BRAIN Initiative, and
the Cancer
Genome Atlas.)

The open test set B (100 one-minute noninvasive fetal ECG recordings)
for Challenge 2013 is now available,
together with a supplement of 50 additional recordings in training set
A.
|
| 21 February 2013 |
This year's PhysioNet/Computing in Cardiology
Challenge invites participants to develop software capable
of detecting fetal QRS complexes in multichannel noninvasive ECG
recordings, making accurate estimates of fetal heart rate, RR
intervals, and QT intervals. An annotated training set of 25
one-minute recordings is available now; a sample entry, software for
scoring, and test recordings will be available shortly.

Open access is now available for the first time to a set of 4000 patient
records included in the MIMIC II Clinical Database
Demo, a downloadable disk image that can be run within a virtual machine or
from a bootable USB flash drive or DVD. Since all of the required software,
including the operating system, is pre-installed and configured, it is an ideal
way to begin exploring the MIMIC II Clinical Database
(currently including more than 32,000 patient records) on a spare PC or Intel
Mac with an absolute minimum of setup time.

Final scores in the PhysioNet/CinC Challenge 2012 have now been posted. Participants will present their
work on the challenge at CinC 2012
in Krakow, 9-12 September.

Inspired by the PhysioNet/CinC Challenge 2011 (Improving the quality of ECGs
collected using mobile phones), the
journal Physiological Measurement has devoted a
focus
issue [2012 Sept;33(9)] to the subject of signal quality in
cardiorespiratory monitoring, with eleven articles on this topic,
including nine written by Challenge participants.

PhysioBank has received a contribution of five-minute multichannel fetal ECG
recordings, with cardiologist-verified annotations of all fetal heart beats,
from five women in labor, from the Medical University of Silesia, Poland. Each
record of the Abdominal and Direct
Fetal ECG Database includes four signals from the maternal abdomen and a
simultaneously recorded reference direct fetal ECG from the fetal scalp; all
signals are sampled at 1 KHz with 16-bit resolution.

The creators of the OB-1
Database of fetal ECGs seek collaborators in their PhysioNetWorks
project to complete the database and to use it to investigate improved
diagnoses of fetal distress. A sample recording from the database is
now available in PhysioBank, while construction of the remainder
(including more than 100 additional recordings, with detailed
accompanying clinical information) is in progress on PhysioNetWorks.

The Cyclic Alternating Pattern (CAP) is a periodic EEG activity occurring
during NREM sleep, and abnormal amounts of CAP are associated with a variety of
sleep-related disorders. The CAP
Sleep Database is a collection of 108 polysomnographic recordings from the
Sleep Disorders Center of the Ospedale Maggiore of Parma, Italy. Each record
includes 3 or more EEG signals together with EOG, chin and tibial EMG, airflow,
respiratory effort, SaO2, and ECG signals, and reference sleep stage and CAP
annotations, This database is intended to provide a useful number of carefully
annotated examples of CAP in a representative variety of pathophysiologic
contexts, for development and evaluation of automated CAP analyzers, as well as
to support basic studies of the dynamics of CAP.

A complete set of over 9 million reference beat and rhythm annotations
for the Long-Term AF
Database has been contributed by MEDICALgorithmics (Warsaw,
Poland). The Long-Term AF Database, a collection of 84 long-term ECG
recordings (typically 24 to 25 hours each) of subjects with paroxysmal
or sustained atrial fibrillation, was contributed to PhysioBank in
2008 by Steven Swiryn and his colleagues at Northwestern University.
Michael Tadeusiak of MEDICALgorithmics coordinated the annotation
development as a PhysioNetWorks project.

PhysioBank has received a contribution
of continuous blood pressure
recordings collected for a study of baroreflex dysfunction in
salt-sensitive hypertension in Dahl SS and SSBN13 rats.

The PhysioNet/CinC Challenge 2012 focuses on
predicting mortality in ICU patients. Sample entries, test frameworks,
scoring functions, and large sets of training and test data are available now.
Update (1 June): Phase 1 of the challenge drew participation from
39 individuals and teams. Phase 2 is now open, until 25 August.

If you have digital recordings of signals or time series, perhaps with
annotations, that you would like to study using PhysioToolkit software
such as that in the WFDB software package, or that you would like to
contribute to PhysioBank, our new tutorial,
Creating PhysioBank
(WFDB-compatible) Records, should get you started on creating
PhysioBank-compatible records from your data.

Use PhysioBank Record Search in your
web browser to find records in PhysioBank that share a desired set of
characteristics. The search engine is integrated with
the PhysioBank ATM, so that records within
search results can be examined individually and marked for further
study if desired. The pbsearch
software package includes sources for the PhysioBank Record Search web
client, the server, a command-line client, and a set of plugins.

The first release of the PhysioBank
Index contains essential information about all of the more than 36,000
records that can be viewed using the PhysioBank ATM. A web-based tool for
searching the index is under development (14 March update: see above). Users
who are comfortable using standard command-line tools can use them now, to
search the index for records with desired characteristics. Our new tutorial
provides guidance and examples.
Update (14 March): The pbindex
software package is now available; it contains the sources for the
software that generates the PhysioBank Index.

Two new tutorials, How to create
and manage a PhysioNetWorks project and
How to Write HTML pages for
PhysioNet, aim to help members of the research community to create,
collaborate on, and publish sharable data and software. Several other
tutorials have been updated recently, including A Brief
Tour of PhysioNet, which now includes a demonstration of the PhysioBank
ATM and an introduction to PhysioNetWorks.

Our new tutorial, Variability vs. complexity,
introduces the study of complex variability, especially in the context of
physiology and medicine.

The PhysioNet/Computing in Cardiology Challenge
2012 is underway. This year's challenge focuses on methods for predicting
mortality of ICU patients, using a rich set of physiologic and clinical
variables collected from 12,000 patients.

The MIMIC II Waveform Database
Matched Subset is now available. It contains 4,897 waveform records and
5,266 numerics records from the MIMIC II Waveform Database, which
have been matched and time-aligned with 2,809 MIMIC II Clinical
Database records.
|
| 6 January 2012 |
The MGH/MF Waveform
Database Patient Guide is now available. It provides additional
information for each recording in the database, including (as available) age,
sex, diagnoses, pertinent medical history, ECG interpretation, ventilation, a
timeline of events that occurred during the recording, and additional clinical
observations.
