  • 加入比較表

EasyBand is a wireless transmitter of single-lead ECG and body temperature for personal use. The device is designed for self-monitoring of users to record a definite period of heart activity and body temperature. Recording is activated manually by the user once discomfort is experienced. Data recorded include timestamp, body temperature, and ECG.

Recorded data can be transmitted via a USB dongle to a PC where data is displayed for intensive analysis and evaluation by physicians.

EasyBand is compact device of 26*28*8.1mm in size and 12g in weight. It can work within 6 meters and up to 48 hours continuously. EasyBand is an ideal device to replace regular event ECG monitor and ECG Holter.

Method of Operation



  • Under normal conditions, the R-R should locate within 600-1000 ms.
  • 5-minute HRV: the average value of the HRV data within the measurement time interval; unit: ms.
  • HF(0.150-0.400): represents the activity of the parasympathetic nerves; unit: ln(ms2).
  • LF(0.040-0.150): represents the integral activity of the autonomic nerves; unit: ln(ms2).
  • VLF(0.003-0.040): currently, it is known that this frequency band is related to vasomotion; unit: ln(ms2).
  • LF%(0~100%): represents the activity of sympathetic nerves; unit: %.
  • LF/HF ratio: similar to LF%, it can represent the activity of the sympathetic nerves; unit: ln(ratio).
  • SDNN: standard deviation of the effective R-R intervals
