Digital ECG of 3 Channels with Printer

ECG300G series three-channel ECG with simultaneous analysis of 12 leads and thermal printing system.


Recording and displaying ECG waveforms in automatic and manual modes, automatic measurement, and automatic diagnostic of parameters of ECG waveform. Data management in memory.


  • LCD-TFT colour screen with 3.5″ monitor, which displays working modes and ECG waveforms. Check the waveform before printing in order to save printing paper.
  • 12 leads of simultaneous acquisition, digital signal processor to obtain an ECG waveform of higher quality through AC filter, baseline filter, and EMG filter.
  • Simultaneous display of 3/6/12 leads of ECG waveform, and printing mode status, sensitivity, speed, filter, etc, to facilitate the interpretation.
  • Includes multiform printing and format modes, such as auto 3*4+1, auto 3.4, auto 2*6+1, auto 2*6, auto 4*3, rythm 4, rythm 3, rythm 2 and manual, etc. Wavelength printing can be adjusted. Moreover, it includes a periodic printing function.
  • Regular self-checking and auto-interpretation of ECG waveform parameter. The device provides measurement parameters such as HR, P-R interval, P duration, QRS duration, T duration, Q-T interval, Q-Tc, P axis, QRS axis, T axis, R (V5), S (V1), R (V5)+S (V1), etc. Moreover, it includes automatic interpretation to help the medical professional.
  • Power supply AC and DC. Rechargeable lithium polymer battery system for 4 continuous operating hours included. 150 ECG waveforms printing, 90 continuous minutes.
  • Large storage capacity to accumulate more than 1,000 records and facilitate the medical analysis and statistics.
