Intended Use
The M2662A Handheld Electrocardiograph is intended for:
• Acquisition, digitization, recording, and retrieval of conventional diagnostic
12-lead simultaneous ECG waveforms and ECG data
• Recording of limited patient information through keypad
• Performing basic auto-measurements of ECG waveforms and preliminary inter-
pretation of measurements (measurements and diagnostic statements are offered
to the physician on an advisory basis only; the physician is asked to review and
validate or change the ECG interpretation.)
As with all electronic equipment, radio frequency (RF) interference
between this cardiograph and any existing RF transmitting or receiving
equipment at the installation site, including electrosurgical equipment,
should be evaluated carefully and any limitations noted before the
equipment is placed in service. Monitoring during electrosurgery should not
be attempted and monitoring electrodes should be removed from the
patient to preclude the possibility of burns. Radio frequency generation
from electrosurgical equipment and close proximity transmitters may
seriously degrade cardiograph performance. Agilent Technologies assumes
no liability for failures resulting from RF interference between Agilent
medical electronics and any radio frequency generating equipment at levels
exceeding those established by applicable standards.
Like all electronic devices, this cardiograph is susceptible to electrostatic discharge
(ESD). Electrostatic discharge typically occurs when electrostatic energy is
transferred to the patient, the electrodes, or the cardiograph. ESD may result in ECG
artifact that may appear as narrow spikes on the cardiograph display or on the
printed report. When ESD occurs, the cardiograph’s ECG interpretation may be
inconsistent with the physician’s interpretation.
ESD discharges to exposed metal on theRS232 port or ECG connector can
occasionally cause an error message to appear on the cardiograph display. The
cardiograph returns to normal operation after the power is turned off, then on again.
