The technological progress allowed the development of more and more sophisticated pacemakers, widening the therapeutic indications but also meeting the physiological needs of the patient. This progress led to a more and more complex programming for the physicians. To help them set optimally the pacing parameters, physicians refer to the existing recommendations of learned societies as well as to his expertise. Manufacturers developed also algorithms integrated into pacemakers with the aim of assisting physicians in their programming.

TherapyGuide is a function which proposes a programming adapted to the psychopathological state of the patient, with a justification based on experts' consensus, clinical studies as well as on published articles.

Physicians have the choice to accept or reject the programming proposed by TherapyGuide. When rejected, there is no means to analyze the modifications brought to the proposed set of parameters. The nature, the frequency and the reasons of these modifications are not thus known.

The purpose of this study is to assess the acceptance of the TherapyGuide proposals by physicians and to identify the most frequent type of programming changes they make and their rationale.
