Resume Objectif Verifier si les frequences cardiaques des patients prenant un traitement par betabloquants (BB) au long cours ou en peri-operatoire etaient optimales lors de la periode peri-operatoire. Methodes Les frequences cardiaques (FC) observees lors de la consultation d'anesthesie, avant l'induction d'anesthesie, et en peroperatoire (FC maximale et minimale) ont ete comparees chez trois groupes de patients repartis en fonction de la prise peri-operatoire de BB, de la prise chronique de BB, ou de l'absence de prise de BB. Les valeurs de FC sont exprimees sous forme de moyenne avec deviation standard. Resultats Au total, 406 patients ont ete inclus : 181 recevaient des BB de facon chronique, 20 ont beneficie d'une introduction preoperatoire et 205 ne prenaient pas de BB. Les FC des patients prenant des BB au long cours etaient plus basses que celles des patients du groupe temoin au repos (67 ± 11 vs 76 ± 12 b/min ; p  Conclusion Les ΒΒ prescrits une semaine avant l'intervention chirurgicale sont plus efficaces pour ralentir la FC que les BB administres de facon chronique.
