Wireless transmission of ECG signal

In this study, the ECG signal were measured as noiseless with Ag/AgCl electrodes, then converted digital data using pulse code modulation (PCM) technique. The digital data were then sent to receiver where it is in 433 MHz FM/FSK transmitter, which has 10 mW output power and 9.6 Kps transmission spee...

Description
Summary:In this study, the ECG signal were measured as noiseless with Ag/AgCl electrodes, then converted digital data using pulse code modulation (PCM) technique. The digital data were then sent to receiver where it is in 433 MHz FM/FSK transmitter, which has 10 mW output power and 9.6 Kps transmission speed. At the receiver, the digital data were reconverted to analog signal to monitor and record on the PC with Sonic Foundry Sound Forge 6.0 program. The power spectrum of measured ECG signal was formed using Matlab program. As a result, the medical supporting system is realized for monitoring the ECG signal on PC of human with chronic heart disease in their living surroundings.
