Antibradycardia pacing
• Sensing: the amplitudes of the P and R waves are measured in the device fully
automatically to record varying amplitudes. The sensitivity for the atrium and
ventricle is adapted automatically on an ongoing basis. The measurement data are
averaged and the trend can be displayed.
• Thresholds: atrial as well as ventricular pacing thresholds are automatically
determined in the device. Capture control is used to set the pulse amplitudes so
that pacing is performed with the optimum atrial and ventricular amplitude for the
patients with each change of the pacing threshold.
• Timing: pacing is particularly checked in the atrium by automatic adaptation of the
atrial refractory period to avoid pacemaker-induced tachycardia. (Auto PVARP
function: automatic post-ventricular atrial refractory period)
• Ventricular pacing suppression: unnecessary ventricular pacing is avoided by
promoting intrinsic conduction (V
itself to conduction changes. In the case of intrinsic conduction, the device switches
to a DDD(R)-ADI(R) mode.
Home Monitoring functions
The device automatically sends information to the transmitter once a day. Additionally,
the test messages can be initiated using the programmer. Important medical
information include, among others, the following:
• Ongoing atrial and ventricular arrhythmia
• Parameters relevant to leads in the atrium and ventricle: pacing thresholds,
sensing amplitudes, impedances
• Current statistics on bradycardia therapy
• Individually adjustable device messages which enhance the device message with
additional information

General Safety Instructions
Possible Medical Complications
General information on medical complications
Complications for patients and device systems generally recognized among
practitioners also apply to BIOTRONIK devices.
• Normal complications may include fluid accumulation within the device pocket,
infections, or tissue reactions. Primary sources of complication information include
current scientific and technological knowledge.
• It is impossible to guarantee the efficacy of antitachycardia therapy, even if the
programs have proven successful during tests or subsequent electrophysiological
examinations. In rare cases the set parameters may become ineffective. In
particular it cannot be excluded that tachyarrhythmias may be induced.
Skeletal myopotentials
Bipolar sensing and control of sensitivity are adapted by the device to the rate range of
intrinsic events so that skeletal myopotentials are usually not sensed. Skeletal
myopotentials can nonetheless be classified as intrinsic events especially with
a unipolar configuration and/or very high sensitivity and, depending on the interference,
may cause inhibition or antiarrhythmia therapy.
