Contraindications
Contraindications
Guidelines
No contraindications are known for the implantation of multifunctional single-
chamber, dual-chamber, or triple-chamber pacemakers, provided differential
diagnostics precedes implantation according to the appropriate guidelines and no
modes or parameter combinations are configured that pose a risk to the patient.
Pacing modes and parameters
The compatibility and effectiveness of parameter combinations must be checked
and, as the case may be, adapted after programming.
Set of facts
Contraindicated pacing mode
Additionally implanted ICD
Unipolar pacing
Set of facts
Inappropriate pacing mode
Chronic atrial tachycardia, chronic atrial
fibrillation or flutter
Atrial-controlled modes (DDD, VDD, AAI)
Poor tolerance of pacing rates above the
basic rate, e.g., angina pectoris
AV conduction disorder
Atrial single-chamber pacing
Failing AV conduction
Set of facts
Adapt parameters
Slow retrograde conduction after
ventricular pacing: Risk of pacemaker-
mediated tachycardia

Poor tolerance of pacing rates above the
basic rate, e.g., angina pectoris
•
Lower atrial upper rate
