Every year in Italy more than 1000 people under 35 years old are victims of sudden cardiac death (SCD). Such an incidence is comparable to that of other Western countries. Pathologies responsible for SCD should be diagnosed as early as possible in order to have effective prevention. The pilot study described in this paper is a particular application of telecardiology. It exploits the teleconsulting paradigm in order to perform a screening in high school students aimed at preventing sudden cardiac death.
