ECG specifications

The ECG channel meets all the requirements for Cardiac Monitors Heart Rate Meters and

Alarms specified ANSI/AAMI EC13-1992, except for Impulse response at the monitor

(section 3.2.9.8 part (c)), and Standardizing Voltage at the monitor and at Acuity (section

3.2.9.9). The channel also meets the American National Standard, Safe Current Limits for

Electromedical Apparatus (ANSI/AAMI ES1-1993).
