Abstract
A case is presented in which a patient with pre-existing first degree heart block developed high-grade second degree heart block during spinal anaesthesia. Progression of the block was associated with blockade of cardiac sympathetic neurons induced by spinal anaesthesia. This suggests that patients with pre-existing heart block may be at increased risk for development of higher grade block during spinal anaesthesia.
Résumé
Le cas présenté est celui d’un patient porteur d’un bloc cardiaque du premier degré à l’ évaluation préopératoire, et qui a développé un bloc du deuxième degré de haut niveau lors d’une anesthésie sous-arachnoïdienne. La progression du bloc était associée au blocage des neurones sympathiques cardiaques induit par l’anesthésie sous-arachnoïdienne. Ceci suggère que les patients avec un bloc cardiaque à l’ évaluation préopératoire peuvent être a risque de développer un bloc de haut niveau pendant une anesthésie sous-arachnoïdienne.
