Pacemaker pulse
rejection.
3.1.4.1,
3.1.4.2
With the exceptions noted below, the monitor will
reject all pacemaker pulses having amplitudes of
±2 to ±700 mV and pulse widths from 0.1 to 2 ms,
with and without under/overshoot. Following are
pacer pulse conditions that the monitor will reject,
but are less than the maximum range listed in the
standard:
Pacer pulse width = 2
ms, double pulse,
without over/undershoot,
no QRS Pacer amplitude =
±300 mV
Pacer pulse width = 2
ms, single and double
pulse, with 2 mV
over/undershoot, no QRS Pacer amplitude =
±300 mV
Pacer pulse width = 0.1
ms, double pulse, with 2
mV over/undershoot,
ineffective pacing Pacer amplitude =
+300 mV, -450 mV
