Audited Supplier Introduction
ECG90A 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", optional interface languages(Chinese/English), case database management.
1)Operation
2.83" TFT-LCD, clear ECG waveform and working state display.
Operation mode: touch screen and function keys.
Compact, delicate and portable design.
2)Functions
1.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.
2. Particular and high accuratedigital filter eliminates baseline drift, no distortion to ECG waveform, greatly
enhances anti-baseline drift capacity, convenient for waveform judgement.
3.Display of 3/6/12-lead ECG, print mode, sensitivity, paper speed and filter state, etc.
on one screen, convenient for contrastively diagnosing.
4.Realtime and continuously record the clear and accurate ECG waveform and annotation character
(including lead mark, sensitivity, paper speed and filter state, etc.).
5.Adopt high-resolution thermal printing system(8 dot/mm), no need for any adjustments.
Recording frequency: up to150Hz.
6.With the functions of auto-analysis and auto diagnosis for routine ECG parameters, provide
measurement results and auto-diagnosis conclusion for HR
7.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. which reduces the doctor's burden.
8.Optional SD card stores up to 100 cases, which is convenient for doctor to review case and statistic.
9.In review mode, case waveform stored can be checked, measurement parameter and diagnosis information
can be automatically analyzed.
10.Two languages(Chinese or English) interface and report
Optional ECG-Sync software, connect with PC by USB2.0 interface to form a ECG workstation, collect real-time data to the software for analyzing and printing the report, and old cases stored in ECG can be uploaded to PC.
3)Power supply
AC/DC, and in optimal DC state, built-in rechargeable lithium battery can continuously work for 4h, print up to 90 minutes and 150-ECG, which meets the requirements of visiting a patient at home and body examination. Rechargeable lithium
battery is detachable, which is convenient for user to replace and charge in any time.
