Intensity and duration of exercise modulate vagal withdrawal and reactivation. Analysis of RR variations, during successive brief exercise bouts at lower and higher intensity, ensures a consistency similar to that reported for autonomic cardiac regulation at rest and might guide the choice among multiple indices that are obtained from the tachogram.
We introduce three new databases of ambulatory Continuous ECG Recordings. The databases consist of 24-hour Holter records acquired in clinical practice from various acquisition devices, including longer recordings from new patch devices.All cardiac events, both rhythm and beat annotations, have been manually reviewed and adjusted by an expert cardiologist with more than 25 years of experience on reviewing Holter data.ECG recordings are organized in different categories based on the predominant arrhythmic events.The databases (total of 1300 records) have been annotated and can be reviewed by CER-S, a software platform used to manage multi-vendor continuous ECG data. CER-S includes two automatic algorithms: 1) ABILE, for the detection of ECG beats and for arrhythmia assessment and 2) BRAVO for the quantitative measurement of the ECG waveforms), either at the beat level or on Time-averaged templates. CER-S has a rich graphical interface with several tools for optimal review and editing both at the ECG beat and arrhythmia level. The tool allows manual entry of other arrhythmia not yet automatically detected by ABILE algorithm and the customization of a clinical report.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
