[Syncope, conduction disorders. Controversial indications for cardiac stimulation].
The objective of permanent pacemaker implantation is to provide against an increased risk of death or to improve quality of life by abolishing symptoms. In both cases, certain indications for pacing have clearly demonstrated to be strongly beneficial in well selected patients, but other are still controversial, due to the lack of convincing and converging published data, or to the absence of general consensus among specialists, or because selection criteria for pacing have been poorly defined. We try to clarify when to pace or not to pace in such conditions as first degree AV block, type I second degree AV block, intracardiac conduction defects, including those occurring at the acute stage of myocardial infarct or after cardiac surgery, sick sinus syndrome in cardiac transplant recipients, carotid sinus syndrome, vasovagal syncope, and unexplained syncopes.
