Implantação de marcapasso com disfunção sinusal em cão: relato de caso

Abstract

A cardiac pacemaker is a medical device used in dogs to correct irregular or slow heart rhythms. It is used to treat various heart conditions such as third-degree atrioventricular block, advanced second-degree atrioventricular block, sick node syndrome or atrial arrest. It works by detecting the electrical activity of the heart and emitting electrical impulses to promote proper contraction of the heart muscle. Implanting pacemakers in animals in Brazil is not yet a common practice, but several professionals and hospitals have already prepared for this type of procedure. However, this implant is considered a necessary measure to ensure the health and well-being of many dogs. This report aims to describe the case of a 10-year-old Lhasa Apso dog referred to the Veterinary Hospital of the Federal University of Uberlândia (UFU), with a history of syncope and bradycardia, diagnosed with sick node syndrome, and who, in order to improve her quality of life to correct her heart rhythm, underwent surgery to implant a transvenous endocardial pacemaker through the external jugular vein until it reached the right ventricle where it was fixed, and later programmed by a technician to adjust it according to the animal's needs.
