Abstract-The design of portable systems for remote monitoring of cardiac activity is one of the most important fields in telemedicine and telecare. In this paper we present a low cost, portable system with wireless transmission for real time ECG acquisition, archiving and visualization both in a mobile phone and a PC. We have implemented the acquisition module and the visualization tool for the mobile device and the PC.

I. INTRODUCTION
Mobile telemedicine systems are becoming more important all the time, especially in the care of patients that are isolated or travelling, far from a reference hospital. These systems must be embedded in low cost, small devices with low power consumption, and should have an interface that is usable by the patient.

Incorporating technologies such as Bluetooth, GPRS, GSM or Wi-Fi to these systems allows the wireless transmission to health or control centers [1-4].

This paper describes a low cost, portable system with wireless transmission capabilities for the acquisition, processing, storing and visualization in real time of the electrical activity of the heart to a mobile phone, a PDA or a PC.

Several groups [5] have developed applications to monitor the ECG in mobile devices, where the samples have been obtained from standard data bases [6], or they have development the ECG module [7]. Other works [810] have proposed techniques for signal processing via software to reduce noise or classify heart pathologies. In this work we describe both the implementation of the acquisition module with wireless transmission capabilities (Bluetooth and GSM/GPRS), and the tool for real time ECG visualization in mobile devices.

The structure is the following. In the following section system analysis, employed technology and development environment are described. In sections III and IV hardware and implemented software will be explained in detail. Results and final prototype, together with the conclusions are shown in section V.
