Gima ECG90A Manuel D'utilisation page 7

1.1 Overview
This product is a kind of electrocardiograph, which is able to sample 12 leads ECG signals
simultaneously and print out the ECG waveform with thermal printing system. Its functions are
as follows: recording and displaying ECG waveform in auto/manual mode; measuring ECG
waveform parameters automatically, and automatic analysis and diagnosis; prompt for
electrode-off and out of paper; optional interface languages(Chinese/English, etc.); built-in
lithium battery, powered either by AC or DC; arbitrarily select the rhythm lead to conveniently
observe abnormal heart rate; case database management, etc.
1.2 Intended use
This product is suitable for hospital, scientific research, wards, ambulances and carrying out
medical consultations. It can be used by medical institutions to record human ECG signals,
collect and extract the ECG waveform.
