Prototype enables 2.45 GHz n-QAM ECG transmission; leaves open prospective clinical validation before adoption.
The developed RF transmission system provides a viable telemedicine solution for ECG signal acquisition and transmission with adequate signal fidelity.
García-Ortega et al. (2023) studied Cardiovascular disease (ECG monitoring). Telemedicine system for ECG analysis with RF transmission (2.45 GHz, n-QAM) was evaluated on Error Vector Magnitude (EVM RMS). The developed telemedicine system for ECG analysis using a 2.45 GHz RF transmission and variable n-QAM schemes achieved an EVM RMS of 8.36 for fifteen OFDM symbol frames, ensuring signal fidelity.
