Pacemaker pulse 
rejection. 

3.1.4.1, 
3.1.4.2

With the exceptions noted below, the monitor will reject all single and 
double pacemaker pulses either 150 or 250 msec apart of amplitudes ±2 to 
±700 mV from 0.1 to 2.0 msec, with and without under/overshoot. 
Following are pacer pulse conditions that the monitor will reject, but which 
are less than the maximum range listed in the standard:

Pacer pulse width = 2 msec,
Double pulse, either 150 or 250 
msec apart without over/
undershoot, no QRS

Pacer amplitude <= ±400 mV

Pacer pulse width = 2 msec, Double 
pulse either 150 or 250 msec apart, 
without over/undershoot, 
ineffective pacer

Pacer amplitude <=±500 mV

Pacer pulse width = 2 msec, Single 
or Double pulse either 150 or 250 
msec apart, with 2 mV over/
undershoot, no QRS.

Pacer amplitude <=±125 mV

Pacer pulse width = 2 msec, 250 
msec spaced double pulse, with 2 
mV over/undershoot, effective 
pacing.

Pacer amplitude <=±300 mV

Pacer pulse width = 2 msec, 150 
msec spaced double pulse, with 2 
mV over/undershoot, ineffective 
pace.

Pacer amplitude <=±220 mV

Pacer pulse width = 2 msec, 250 
msec spaced double pulse, with 2 
mV over/undershoot, ineffective 
pace.

Pacer amplitude <=±120 mV
