FeaturesA. 8"TFT Color LCD screenB. 12 Leads ECG simultaneous gather, digital signal processing, to get the ECG waveforms of higher quality through the AC, DFT and EMG filtering of the ECG signals.C. Simultaneous display of 3/6/12 leads ECG waveform, and the state of printing mode, sensitivity, speed, filter etc, to be easy for contrast diagnosis.D. Multiply printing modes and formats, including 12*1, 6*2+1(rhythm lead), 6*2, rhythm 12, rhythm 10, rhythm 8, rhythm 6, manual and freeze, etc. The length of printed wave can be adjusted and simultaneity the function of periodic printing is offered to satisfy different applications.E. functions of auto-analysis and auto-diagnosis of regular ECG waveform parameters, provides measurement parameters such as HR, P-R interval, P Duration, QRS Duration, Q-T interval, Q-Tc, P Axis, QRS Axis, T Axis, R(V5), S(V1), R(V5)+S(V1), etc and auto-diagnosis conclusion to reduce doctor's burden.F. AC/DC power supply. Built-in rechargeable lithium polymer battery. At the best DC state, it can standby for 10 hours, print less than 3 hours, and print 300 pieces of ECG waveform G. Built-in MSF, can store more than 1000 casesChinese/English/Spanish/Turkish/German/Portuguese/Kazakhstan/Russian operation interface and can print H. provides multiply printing speeds, including 5mm/s, 6.25mm/s, 10mm/s, 12.5mm/s, 25mm/s, 50mm/s, and abstract conclusion graph printing.
