A electronic vital-sign monitoring system is provided here, which uses an external electronic device to compute a physiological value detected by an electronic vital-sign monitoring device and obtain a heart frequency spectrum； and provide power to the electronic vital-sign monitoring system； and further transfer the computed physiological value and the heart frequency spectrum to a database for data integration and incident reporting. In addition to the original function of detecting physiological values, the electronic vital-sign monitoring system further can detect heart frequency spectrum and offers telecare service to help patients, elders and general users according to different requirements.
