Does RF-ECG using COTS RFID accurately measure heart rate variability compared to wired techniques in human volunteers?
RF-ECG using COTS RFID tags provides a wireless, non-invasive method for estimating heart rate variability with accuracy comparable to wired ECG.
Wang et al. (2018) studied Heart Rate Variability (HRV) measurement (n=15). RF-ECG based on COTS RFID vs. Existing wired techniques was evaluated on Median error of Inter-Beat Interval (IBI). RF-ECG based on COTS RFID achieved a median error of 3% for Inter-Beat Interval (IBI) estimation in 15 volunteers, comparable to existing wired techniques.
