Chapter1 Overview
1.1 Overview
12-channel Electrocardiograph is such a kind of electrocardiograph, which gathers 12-lead ECG
signals simultaneously and prints out the ECG waveforms with thermal printing system. It's
major functions are as follows: recording and displaying ECG waveforms in manual/auto ways;
measuring and diagnosing ECG waveform parameters automatically; electrode-off and paper
lack prompt; optional interface languages (Chinese/English); powered either by AC or DC;
selectable rhythm lead to detect abnormal heart rate conveniently ;case database management,
etc.
800*600 dots high resolution LCD screen; 1728 dot wide, it can print 12-channel ECG
waveforms. You can operate either by buttons or touch screen, which is convenient and quick.
