Questioning the cost-benefit ratio of the telecardiology service in the state of Minas Gerais.

Regarding the costs related to the physicians writing ECG reports, the authors have informed that the cardiologists who analyze the ECGs take turns in shifts to cover the entire state of Minas Gerais. The cost of those professionals, however, has not been informed in the analyses performed in that article. Another important factor not specified in that article is whether all elective and emergency exams are sent to the reference centers for ECG report. The answer to that question also influences the costs approached in the article. In addition, we would like to consider the possibility of creating a single center for ECG report instead of its distribution in the five universities as reported in that article. Was that alternative considered to reduce costs in the feasibility analysis? It is worth noting that those questions do not diminish the positive impact of the project. On the contrary, its merit is evident. We aimed at helping refining the cost informed to enable its comparison with other solutions available in the market.
