ECG90A is an Electrocardiograph which can collect 12-lead ECG signal
simultaneously and print waveform by the thermal printing system. It features
in, recording and displaying ECG waveform in AUTO/Manual mode, measuring and
diagnosing ECG waveform parameters automatically, prompting for “Lead off” and
“Lack of paper”, multi-language interface, case database management.
Note:
The device sold to the countries and regions that have FDA certification
requirement does not support automatic analysis function.
1)Sync collection
for 12-lead ECG, adopt digital signal processing technology and get high-quality
ECG waveform via power frequency filter, baseline filter and EMG filter of ECG
signal.
2)Particular and high-accuracy digital filter eliminates baseline
drift, no distortion to ECG waveform, greatly enhances anti-baseline drift
capacity, convenient for waveform judgment.
3)Display of 1/3/6/12-lead ECG,
print mode, sensitivity, paper speed and filter state, etc. on one screen,
convenient for contrastively diagnosing.
4)Real-time and continuously record
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, no need for any adjustments. Recording frequency: up to
150 Hz.
6)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, 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.
7)Optional SD card stores up to 100 cases, which is convenient for
doctor to review case and statistic.
8)In review mode, case waveform stored
can be checked, measurement parameter and diagnosis information can be
automatically analyzed.
9)Multi- language(Chinese, English) interface and
report.
10)Optional ECG-Sync software, connect with PC by USB2.0 interface to
form a ECG workstation, import real-time data to the software for analyzing and
report printing, and old cases stored in Electrocardiograph can be uploaded to
PC.
11)Power supply: AC/DC and built-in rechargeable lithium battery. In
optimal DC state, up to 4-hour standby time, continuous print 90-minute and
150-ECG, which meets the requirements of visiting a patient at home and body
examination.
