Manufacturing and tests of a mobile ecg platform

One of the challenges in the biomedical engineering domain is the Telemedicine. The remote diagnosis, automate instruments for drug delivery or mobile platforms for domestic applications are common targets accepted by the medical insurance companies form the world wide. The Telemedicine need the development of various tools for home analysis, in order to send all the collected analysis to a medical center or to a database on Internet. In this paper is proposed a simple and cheap platform for the Electro-cardio-gram recording on the Personal Computer. The platform consists in a hardware part and a software part. The general electrical circuit for the ECG recording was adapted in order to be available at home applications. The amplified signal is then connected via the microphone muff to PC. A dedicated software converts the input ldquonoiserdquo signal into an ECG trace. In this way, the ECG becomes available, in the simpler mode directly on the computer screen, without any expensive tracer.
