Introduction
ECG300G is an electrocardiograph that can collect 12-lead ECG signals and print the waveform using a thermal printing system. It features recording and displaying ECG waveform in AUTO/Manual mode, automatically measuring and diagnosing ECG waveform parameters, indicating "Lead off" and "Paper lack", multilingual interface, AC/DC, selection of any rhythm lead, case database management.
Function
1) 12-lead synchronization for ECG collection, adopts digital signal processing technology and obtains high-quality ECG waveform through power frequency filter, baseline filter and EMG filter of the ECG signal.
2) Display of 3/6/12 leads ECG, printing mode, sensitivity, paper speed and filter status, on one screen etc., convenient for contrastive diagnosis.
3) Multiply print modes and formats, including manual, auto 4 × 3, auto 3 × 4 + 1, auto 3 × 4, auto 2 × 6 + 1, auto 2 × 6, auto 3-2 + 1, auto 3-2, Auto 1 × 12 + 1, Auto 1 × 12, rhythm 4, rhythm 3 and rhythm 2, etc. The length of printed waveform can be adjusted and with the time print function, which meets different requirements.
4) With auto-analysis and auto-diagnosis functions for routine ECG parameters, it provides 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 burden of the physician.
5) Built-in memory stores up to 1000 cases, convenient for case review and statistics.
6) Multi-language interface and report (Chinese, English, Spanish, Turkish, Polish, Italian, French, German, Portuguese, Kazakh, Russian, Ukrainian, Serbian and Slovenian).
