Introduction

ECG300G is an electrocardiograph collecting 12-lead ECG signal simultaneously and printing ECG waveform with thermal printing system, which features in, recording and displaying ECG waveform with manual or auto mode, measuring and diagnosing ECG waveform parameters automatically, prompting for “Lead off” and “Lack of paper”, multi-language interface, case database management.

Features

1)Operation

• 3.5" color LCD, accurate and clear ECG waveform and working state display, economical to save recording paper.

2)Functions

• Sync collection for 12-lead ECG, adopt digital signal processing technology to get high-quality ECG waveforms via AC filter, baseline filter and EMG filter of ECG signal.
• Display of 3/6/12-lead ECG, print mode, sensitivity, paper speed and filter state, etc. on one screen, convenient for contrastively diagnosing.
• Multiply printing 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. Waveform length printed can be adjusted, and with timing print function, which meets different requirements.
• 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.
• Built-in memory stores up to 1000 cases, convenient for case review and statistic.
• Multi-language(Chinese, English, Spanish, Turkish, Polish, Italian, French, German, Portuguese, Kazakstan, Russian, Ukrainian, Serbian and Slovenian) interface and report.

3)Power supply

• AC/DC, and in optimal DC state, built-in rechargeable lithium battery can continuously work for 10h, print for more than 3h and 260-ECG, which meets the requirements of visiting a patient at home and body examination.
