We introduce a new database of ambulatory Continuous ECG Recordings. The database mainly consists of 24-hour Holter records acquired in clinical practice, and is being constantly updated with new recordings from various acquisition devices, including longer records 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. Only recordings with minimal noise (1 minute/hour maximum, except for the very beginning and end of the recording) were considered eligible for database enrolment. ECG recordings (total 1068) are organized in different categories based on the predominant event/activity: Ventricular Tachycardia (#30), Atrial Ventricular Block (#6), Atrial Tachyarrhythmia, including Atrial Fibrillation, Atrial Flutter and Atrial Tachycardia (#268), Premature Ventricular Contraction (#240), Premature Atrial Contraction (#1), Pause (#6) and Normal Sinus Rhythm (#517). In addition, we will introduce CER-S, a software platform used to manage multi-vendor continuous ECG data that was used for the annotation of the database and which is used as a viewer for the recordings. The platform also includes two automatic algorithms ABILE, for the detection/classification of ECG beats based on morphology and for arrhythmia assessment (including Atrial fibrillation, main Ventricular and Supraventricular activity, VT, SVT, Pause, Bradycardia and Sinus Tachycardia), BRAVO for the measurement of the ECG beats (including standard time interval annotations and ST displacement, both at a beat-to-beat level and Time-averaged) and 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.
