Key result
A mobile phone-based system for distant simultaneous monitoring of ECG signals was developed, and the feasibility of its signal processing algorithms was confirmed through MATLAB simulations.
Demonstrates the technical feasibility of using mobile phones for distant simultaneous monitoring and transmission of ECG signals.
Technical feasibility of mobile ECG monitoring shown in simulation; leaves open clinical validation and utility.
Telemedicine is being rapidly developed. In isolated places, i.e. islands, mountains or ships, where access to medical services is time-consuming or infeasible, it can prove life-saving. Powerful programming languages such as C++ and Java™ are supported by the modern mobile phones, which gives a possibility for easy developing of useful telemedicine applications. In this paper we present an approach for distant simultaneous monitoring of several ECG signals. The individual channel signals are packed through modulation into a complex sound signal, which is further recorded by a mobile phone. The phone is interfaced to the measuring device through a modified hands-free accessory. JAVA applications allow storing the signals in multimedia files and their transmitting to a second mobile phone via MMS or other means. A real-time ECG monitoring is also possible. The feasibility of the signal processing algorithms is confirmed through simulations in MATLAB.
