New Database Added: Tai Chi, Physiological Complexity, and Healthy Aging-Gait Database
11 May 2017 12:00:00 AM EST
The Tai Chi, Physiological Complexity, and Healthy Aging-Gait database contains two-channel gait recordings of 87 older adults from the Greater Boston area. Subjects were from a hybrid study design that included a two-arm randomized clinical trial (RCT) along with an additional observational comparison group. A description of the dataset and its collection methods are described in A Systems Biology Approach to Studying Tai Chi, Physiological Complexity and Healthy Aging: Design and Rationale of a Pragmatic Randomized Controlled Trial.

The National Sleep Research
Resource (NSRR) has expanded its research databases and tools,
as well as launching a series of tutorials on their use. The NSRR is
supported by the National Heart, Lung, and Blood Institute (NHLBI)
of the NIH.
New Database Added: Preterm Infant Cardio-Respiratory Signals Database
09 February 2017 12:00:00 AM EST
The Preterm Infant Cardio-respiratory Signals (PICS) database contains simultaneous ECG and respiration recordings of ten preterm infants collected from the Neonatal Intensive Care Unit (NICU) of the University of Massachusetts Memorial Healthcare. A description of the dataset and its collection methods are described in Predicting Bradycardia in Preterm Infants Using Point Process Analysis of Heart Rate.
The PhysioNet/Computing in
Cardiology Challenge for 2017: AF Classification from a short single lead ECG
1 February 2017 5:00:00 PM EST
We are excited to announce the opening of the annual PhysioNet/Computing in Cardiology Challenge for 2017: AF Classification from a short single lead ECG recording. A database of over 10,000 ECG recordings is being made freely available exclusively for this competition by AliveCor, and represent a serendipitous sample of patient-initiated recordings of one minute or less. They have all been labeled for rhythm by hand into one of four categories: Normal, Atrial Fibrillation, Other Rhythm or Too Noisy to Process. We challenge the public to develop the most accurate classifier of these data into these four categories. As usual, a portion of these data have been hidden from the public to allow us to objectively assess your algorithms. More information on the Challenge, including data and example code can be found at http://physionet.org/challenge/2017/.
New Database Added: STAFF-III Database
31 January 2017 12:00:00 AM EST
The STAFF-III database was acquired during 1995-96 at Charleston Area Medical Center (WV, USA) where single prolonged balloon inflation had been introduced to achieve optimal results of percutaneous transluminal coronary angiography (PTCA) procedures, replacing the typical series of brief inflations. The database consists of standard 12-lead ECG recordings from 104 patients. A description of the dataset and its collection methods are described in Spatial, individual and temporal variation of the high frequency QRS amplitudes in the 12 standard electrocardiographic leads.
