Sick sinus syndrome in a dog: treatment with dual-chambered pacemaker implantation

Heather Burrage. Can Vet J. 2012 May.

Abstract
in English, French

A 2-year-old male castrated boxer dog was presented because of a history of syncope. Electrocardiogram tracings obtained with a cardiac event monitor showed bradycardia culminating in asystole. Sick sinus syndrome was diagnosed and treated with transvenous implantation of a dual-chambered permanent pacemaker.

Syndrome du dysfonctionnement sinusal chez un chien : traitement par l’implantation d’un stimulateur cardiaque à double chambre. Un chien Boxer castré âgé de 2 ans a été présenté en raison d’une anamnèse de syncope. Les tracés d’électrocardiogrammes obtenus avec un moniteur de l’activité cardiaque ont montré une bradycardie culminant par une pause cardiaque. Le syndrome du dysfonctionnement sinusal a été diagnostiquée et traitée par l’implantation d’un stimulateur cardiaque à double chambre.
