Apply telemetry in biomedical signal monitoring allows to control parameters continuously patients preventing future health complications and increasing the efficiency of the medical staff, through these systems, can serve more patients at a time. This article discusses the importance of telemetry in biomedical signal monitoring and designing a prototype with a Bluetooth transmission module electrocardiographic signal (ECG). The design presented ranging from the digitization of the signal and its transmission via bluetooth to your reception and visualization software implemented in Android supervisor. In testing apparatus is employed for amplifying the ECG signal (which is in the order of millivolts) to a voltage range suitable for scanning. Emphasizes not cover the acquisition stage of the signal it is assumed that the signal is amplified.
