Novel pacing algorithms: do they represent a beneficial proposition for patients, physicians, and the health care system?

Modern pacemakers are enriched with several embedded algorithms, aiming at achieving a more "physiological" pacing, at reducing pacing-related costs and at maximizing the physician's and the patient's convenience. Though some of these algorithms offer proven benefits, the efficacy of others is still under serious dispute. Herein are presented some of the most important algorithms integrated in modern pacemakers, together with an overview of the currently available literature concerning their efficacy and safety, as well as their impact on the economics of health care systems.
