displacement slope
error in lead
weighting factors
hysteresis after 15-mm
deflection from baseline
Standardizing voltage:1)
nominal value
rise time
decay time
amplitude error
Input impedance at
10Hz (each lead)
DC current (any input lead)
DC current (any other patient
electrode)
Common mode rejection:
allowable noise with 20 V,
60 Hz & ± 300 mV dc &
51-kilohm imbalance
System noise:
RTI, p-p
multichannel crosstalk
Baseline control and stability:
retun time 10 s
after reset
return time after
lead switch
Baseline stability:
baseline drift
rate RTI
total baseline drift
RTI (2-min period)
Overload protection:
No damage from differential
voltage, 60-Hz, 1 - V p-p,
10-s application
No damage from sumulated
defibrillator discharges:
overvoltage
energy
recovery time
energy reduction by
defibrillator shunting
transfer of charge through
defibrillator chassis
ECG display in presence
of pacemaker pulses:
amplitude
pulse duration
rise time
frequency
Risk current (isolated
patient connection)
Auxillary output (if
provided):
no damage from short circuit
risk current (isolated
patient connection)
