The ECG 1200G is an electrocardiograph that can capture 12-lead ECG signals simultaneously and print the ECG waveform using a thermal printing method. It has the following features: recording and displaying ECG waveforms in AUTO/Manual mode, automatically measuring and diagnosing ECG waveform parameters, prompting for “Lead off” and “Lack of paper”, multi-language interface, AC/DC, rhythm lead selection, printing the trend chart and histogram of the P-R interval, and case database management.
