ECG300G Digital Three Channel ECG


■3.5"TFT Color LCD shows the working status and ECG waveform. Check the waveform before printing to save record paper.
■12 Leads ECG simultaneous acquisition, digital signal processor, to get higher quality ECG waveforms through the AC filter, baseline filter and EMG filter of the ECG signals.
Simultaneous display of 3/6/12 leads ECG waveform, and the state of printing mode, sensitivity, speed, filter etc, to be easy for interpretation.
■Include multiform printing modes and format, such as 4, 3+1(rhythm), 3, 2+1(rhythm), 2, 3(Limb lead) + 2(Chest lead) + 1(rhythm), 3(Limb lead) + 2(Chest lead), rhythm 4, rhythm 3, rhythm 2, Manual etc; the length of wave printing can be adjusted and the function of periodic printing is included to satisfy different applications.
■The instrument has the function of regular auto-analysis and auto-interpretation of ECG waveform parameter, 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 and auto-interpretation conclusion to help reducing doctor's abundance and improve working efficiency.
■The power supply includes both AC/DC. This device includes built-in lithium polymer rechargeable battery. It can standby for 4 hours, print 150 pieces of ECG waveform and print 90 minutes continually under the best DC state to satisfy the need of visiting patients and physical examination.
■It has build-in storage with large capacity, and can memory more than 1000 cases, which is easy for doctor review and statistic.
Support Chinese, English, Spanish and Turkish operating interface, can print out Chinese or Endlish report.
■Option: ECG-Sync software, connect with the PC by USB connector to form a ECG workstation, collect real-time data to the software to analyze and print the report, and can update the old cases in the ECG machine to PC. It has optional functions of FCG, HFECG, QTd, HRV analysis etc.
