ECG Machine 3 Channel 12 Leads

ECG Machine can collect 12-lead ECG signal and print waveform by the thermal printing system. Recording and displaying ECG waveform in AUTO/Manual mode, measuring and diagnosing ECG waveform parameters automatically, prompting for “Leadoff” and “Lack of paper”, multi-language interface, AC/DC, selecting any rhythm lead, case database management.


ECG300G three channel ECG is such a kind of electrocardiograph,which samples 12 leads ECG signals simultaneously and prints out the ECG waveforms with thermal printing system. Its functions are as follows:recording and displaying ECG waveforms in auto/manual mode;auto-measuring and auto-diagnosing the ECG wave parameters;prompting the state of lead off and paper lack;switching the interface lauguages (Chinese/English);managing the case database.


◆3.5" TFT Color LCD display 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 auto 3*4 +1, auto 3*4, auto 2*6 +1, auto 2*6,  auto 4*3, rhythm 4, rhythm 3, rhythm 2 and 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 the doctor review and statistic.

◆Support Chinese, English, Spanish, Turkish, Polish, Spanish, French, German Operating interface, can print out Chinese, English, Polish report.
