Introduction
ECG1200G is an  electrocardiograph which can collect 12-lead ECG signal simultaneously and print  ECG waveform with thermal printing system. It features in, recording and  displaying ECG waveform in AUTO/Manual mode, measuring and diagnosing ECG  waveform parameters automatically, prompting for “Lead off” and “Lack of paper”,  multi-language interface, AC/DC, selecting rhythm lead, printing the trend chart  and histogram of P-R interval, case database management.

Function
1)Sync collection for 12-lead  ECG, adopt digital signal processing technology and get high-quality ECG  waveform via power frequency filter, baseline filter and EMG filter of ECG  signal.
2)Display of 3/6/12-lead ECG, print mode, sensitivity, paper speed  and filter state, etc. on one screen, convenient for contrastively  diagnosing.
3)Multiply printing modes and formats, including auto 12x1, auto  6x2+1, auto 6x2+1_H, auto 6x2, auto 6x2_H, auto 3x4+1, auto 3x4+2, rhythm 12,  rhythm 10, rhythm 8, rhythm 6, manual, etc. Trend chart and histogram of P-R  interval can be printed, waveform length printed can be adjusted, and with time  print function, which meets different requirements.

4)Paper speed: 5mm/s,  6.25mm/s, 10mm/s, 12.5mm/s, 25mm/s, 50mm/s.
5)With the functions of  auto-analysis and auto-diagnosis for routine ECG parameters, provide measurement  results and auto-diagnosis conclusion for 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. which reduces the doctor’s burden.
6)Built-in memory  stores up to 1000 cases, convenient for case review and  statistic.
7)Multi-language(Turkish, French, Chinese, English, German,  Kazakstan, Polish, Portuguese, Russian, Slovenian, Spanish and Ukrainian)  interface and report.
8)In optimal DC state, up to 10-hour standby time,  continuous print more than 3-hour, record up to 300 ECG waveform(commonly, it is  3s case), which meets the requirements of visiting a patient at home and body  examination.
