ECG Specifications
The ECG channel meets all the requirements for Cardiac Monitors Heart Rate Meters and Alarms
specified ANSI/AAMI EC13-1992, except for Standardizing Voltage (section 3.2.9.9). The channel also
meets the American National Standard, Safe Current Limits for Electromedical Apparatus
(ANSI/AAMI ES1-1993).
