Medical diagnosis is a fundamental field to detect potential diseases and illness in patients. Nowadays, decision support systems used to detect health problems present several technical advances with respect to the existing systems 20 or 30 years ago. This work is associated to this evolution in diag- nostic systems. In this work, a low cost electrocardiography system is devel- oped. The system is able of acquiring patient medical information and send it to a medical center in execution time. This system can be used as an alternative to the current Holter monitors in daily life to record heart activity for 24 hours.

According to a report from Strategy Analytics [1] the sales of smartphones grew 40% to reach around 990.0 million units sold; this report give us an idea of the great impact of the smartphones in our society [2][3][4]. Smartphones can be explored as technological tools that can help humans in different ways and a critical field where smartphones can be applied is health care. Nowadays, it is possible to find a variety of "silent" diseases. These diseases don’t have symptoms but they are in continuous evolution. Some examples of these diseas- es are diabetes, hypertension or hypercholesterolemia [5][6], they can lead to im- portant pathologies in the future such as myocardial infarction and stroke, associated with a high mortality among adults. However, an early diagnosis and a correct treatment and control, can notably help the patients to avoid the consequences of these diseases and to prolong the quality of life [7][8].
