Abstract
The introduction of programmed electrical stimulation of the heart opened up new ways for the diagnosis and treatment of recurrent tachycardias.
Programmed stimulation not only allows study of the site of origin and mechanisms of arrhythmias, but also the evaluation of the modes of reproducible initiation and termination of tachycardia and the study of effects of drugs on the tachycardia mechanisms. By analyzing results of invasive and non-invasive programmed stimulation, the most successful pacing modality to reproducibly terminate tachycardia can be identified, but complications of pacing can also be recognized (such as the initiation of other arrhythmias).
Careful consideration of the results of programmed electrical stimulation is necessary to select the best implantable unit for a particular patient, and to design or redesign new or already implanted antitachycardia units.
