Objective To validate the reliability and performance of a real-time wireless electrocardiogram( ECG) recording system utilizing Bluetooth technology (Bluetooth System). Methods Bluetooth System was tested on 30 cases. 2 electrocardiograms were recorded in all cases by Bluetooth System and MAC-5000 Resting ECG System(MAC system), respectively. 4 aspects of electrocardiograms were compared between 2 systems including the general waves, clinical diagnosis, time and voltage parameters. Results Bluetooth system was the sames as MAC system in the general waves and clinical diagnosis of electrograms. Comparing to MAC system, only the voltage of R wave in lead Ⅱ and P wave in lead V_5 is higher(0.866±0.521 mV vs 0.840±0.517 mV, 0.069±0.054 mV vs 0.060±0.048 mV)in Bluetooth system (P0.05). There was no significant difference found in the other time and voltage parameters between 2 systems. Bluetooth system showed high safety in data transmission. Conclusion Bluetooth system has the same accuracy to MAC system in recording electrocardiogram. Bluetooth system is reliable for recording electrographic signals.
