Contraindications
•
Reocor D cannot be sterilized and is therefore not suit-
able for use within the sterile field.
•
The atrially triggered pacing modes (DDD and VDD) are
contraindicated for atrial fibrillation, atrial flutter and
other fast atrial rhythms.
•
When high ventricular rates are not well tolerated by the
patient (e.g., in the presence of angina pectoris), atrium-
controlled modes can be contraindicated.
•
If retrograde conduction is encountered after ventricular
pacing, extending the atrial refractory period and/or
shortening the AV delay may be necessary programming
options to prevent pacemaker-mediated tachycardia. It
may be necessary in such cases to program a VVI mode.
•
Atrial single-chamber pacing is contraindicated for
patients with existing AV conduction disturbances.
•
The use of an external pacemaker is contraindicated in
the presence of an active, implanted pacemaker.
Potential Side Effects
Potential complications associated with the application of
temporary external pacing include asystole after abrupt ces-
sation of pacing (e.g., if the patient cable is inadvertently
disconnected, the leads are loosened or the settings are
incorrect) or pacemaker dependency.
Complications when inserting transvenous leads include:
Wound infection, arterial puncture, pericardial friction,
cardiac perforation and dysrhythmia after lead insertion.
Handling Instructions
Depending on the pacing settings and the patient's under-
lying illness, pacing can induce arrhythmias. To ensure the
patient's safety, certain procedures should be observed and
