Pacer Refractory Test
The Pacer Refractory test checks the ability of the
pacemaker to interact with cardiac activity when the
pacemaker is in demand mode. Ansur retrieves the
Pulsed Refractory Period (PRP) and the Sensed
Refractory Period (SRP) timings as measured by the
Analyzer. Tables 13 and 14 list the Pacer Refractory test
measurements and custom parameters.
Table 13. Pacer Refractory Test Measurements
Measurement Unit of Measure Description
Sensed Rp milliseconds Sensed Refractory Period: period of time that immediately follows sensing of
cardiac activity during which time the pacemaker does not sense further cardiac
activity
The Analyzer measures SRP from the peak of the first ECG R-wave complex to
the next ECG R-wave complex following pacemaker pulse.
Paced Rp milliseconds Pulsed Refractory Period: period of time immediately following pacemaker pulse
during which time the pacemaker senses no cardiac activity and its output is not
inhibited
The Analyzer measures PRP from the leading edge of the pacemaker pulse to
the peak of the first ECG R-wave complex.
