GARRIDO MARTINEZ, Lourdes  and  GONZALEZ FERNANDEZ, René Iván. ECGEstudio: Tool for the diagnosis of cardiovascular diseases. RCIM [online]. 2015, vol.7, n.2, pp. 153-164. ISSN 1684-1859.

The aim of this paper is to discuss the main features of a system developed for the resting ECG analysis. The proposed system is composed of an electronic ECG module for signal acquisition and transmission via USB, a personal computer and a Windows application developed on .NET technology. Trend studies, based on several ECGs from a patient, are made to analyze the evolution of ventricular hypertrophy, the propensity to sudden death and the recovering degree after suffering a heart attack; this kind of study is not available in traditional electrocardiographs. The proposed was designed as a layered structure with levels of abstraction to facilitate their continued maintenance and updating. Microsoft Visual Studio 2010 was selected as the development environment and SQL Server Compact as the database manager. The system was tested with simulated ECGs and signals from volunteers with heart rates between 30 and 240 beats per minute, giving sensitivity in QRS complex detection over 99 %.
