WARNING
3 ECG accessories are not suitable for DIRECT CARDIAC APPLICATION (Refer to
IEC60601-1 for more information about the definition of DIRECT CARDIAC
APPLICATION).
CAUTION
A different type of electrodes may produce higher offset voltage. Therefore, only use the
ECG leads supplied by the manufacturer when using the monitor for ECG monitoring.
NOTE:
Interference from a non-grounded instrument near the patient and ESU interference can
cause inaccuracy of the waveform.
A good ECG signal should be –
1) With normal QRS wave.
2) Tall and narrow with no notches.
3) With tall R-wave completely above the baseline.
4) With T-wave less than one-third of the R-wave height.
5) With P-wave much smaller than the T-wave.
