ECG annotated databases are used to test the performance of algorithms used for ECGs analysis. Nevertheless, the annotated databases available are quite expensive, or even when free, they are provided in “limited-size” versions to the research community with so specific formats that make difficult their integration into a single database. This paper presents CardioLib, a Windows platform application integrates multiple annotated databases into a single collection of ECGs of patients with multiple pathologies. CardioLib is intended 1) to import different digital ECG formats into a single database -i.e. SCP, and the formats used in Physiobank databases- in order to allow the international referenced validity of ECGs interpretation algorithms, 2) to annotate new rest ECGs into the system database, increasing the system data volume, and 3) to generate statistical reports. Graphic tools were included in order to allow the measurement of the duration and amplitude of signal intervals, segments and waves. An editing tool is provided in order to check and to modify the ECG measurements and the cases diagnosis; this editor includes facilities for filtering, ordering, and updating the information. Two thousand anonymous cases recorded by different digital electrocardiographs had been stored and annotated as part of a first version of this program. The annotated database of CardioLib is used nowadays as reference to evaluate several methods and algorithms included in the ECG devices developed at the Central Institute for Digital Research in Cuba.
