3. CONTRAINDICATIONS
3.1. GENERALITIES
There are no known contraindications to the use of cardiac
pacemakers as a therapeutic method for controlling heart rate.
Nevertheless, the patient's medical and physical condition, as well as
age, should be taken into consideration when choosing the
pacemaker and leads.
The benefits of pacing to pediatric subjects have not been evaluated.
Adverse interactions may occur between the patient's spontaneous
rate and pacemaker functions.
3.2. POTENTIAL COMPLICATIONS
Complications may arise with any implanted pacing system. They
may be related to the device itself:
! Early battery depletion
! Component failure
! Circuit inhibition, reversion to standby mode, or other failures due
to electromagnetic interference
! Pectoral stimulation
Complications may be related to the pacing leads:
! Poor connection to the pacemaker leads
! Lead displacement, cardiac wall perforation, or tissue reaction at
the myocardium-electrode interface
! Insulation fracture
! Conductor fracture
Medical complications may also arise:
! Infection
! Fluid accumulation at the implant site
