Automatic Threshold Test in the Ventricle
The prerequisites for an automatic threshold test in the ventricle are as
follows:
• Ventricular rate

100 bpm
• Adequate signal quality
• The implant is not set to mode switching
P/R-Wave Test
A P/R-wave test is available for measuring the amplitude of
spontaneous events during follow-up examinations. This test measures
the minimum, mean, and maximum amplitude values over several
cycles. This provides a simple and reliable method for adjusting the
sensitivity of the pacemaker's sensing features. An optional realtime
printout contains an amplitude annotation of the measured value in
each individual cycle.
Retrograde Conduction Test
Valid for Cylos
To measure the retrograde conduction time, an appropriate test
function is available at follow-up. During the test, the patient is paced
at an increased ventricular rate over several cycles while the VA interval
is measured. (This is the time between ventricular pacing and the
subsequent atrial sensing). The result is displayed as a minimum,
mean, and maximum value. An optional realtime printout contains an
amplitude annotation of the measured value in each individual cycle.
External Pulse Control (NIPS)
The pacemaker offers a high-speed digital communication mode that
enables the transmission of pacemaker pulses to be controlled with the
programmer.
