A database for evaluation of algorithms for measurement of QT and other waveform intervals in the ECG

A cell-centered database for electron tomographic data

“…Databases like the CCDB provide a varied source of raw data for those interested in developing new algorithms for reconstruction, segmentation, visualization, or image analysis of electron tomographic data. The utility of databases for spurring analysis tools has already been shown (Laguna et al, 1997;Shindyalov and Bourne, 2001).…”

A novel robust index to assess beat-to-beat variability in heart rate time-series analysis

“…Fig. 3, for example, shows the results for the sel103 recording of the MIT-BIH QT database [7]. The rMSDD and pNN50 have been calculated in a moving window of 100 beats width.…”

Can Supervised Learning Be Used to Classify Cardiac Rhythms?

“…We evaluated the true positive rate and positive predictivity of our CNN model by comparing the resulting annotations with the reference annotations given for the QT database [4]. A strict tolerance level of 25 ms and 50 ms was set for the time difference between both annotations to count as successful (true positive).…”

“…were taken from the QT database [4]. We included realistic noisy segments, which were generated by applying the WFDB function nst [5] to clean records at different and very low signal-to-noise ratios (see [6]).…”
