Abstract
A one-year-old Abyssinian cat was referred for episodes of vacancy, exaggerated blinking, and intermittent collapse episodes. A 12-lead electrocardiogram (ECG) and ECG telemetry demonstrated sinus bradycardia, sinus pauses, and sinus arrest with a junctional escape rhythm. No infectious agents were identified as a cause of the bradyarrhythmia during systemic disease screening. Findings were consistent with idiopathic sick sinus syndrome. Theophylline therapy did not improve clinical signs or ECG findings. An epicardial pacemaker was placed, which alleviated clinical signs. Pacemaker interrogation after implantation showed minimal use of the pacemaker. This case report highlights the utility of ECG telemetry in describing electrocardiographic findings of sinus arrest, a junctional escape rhythm, and sinus bradycardia in a cat with clinical signs, consistent with sick sinus syndrome which resolved following epicardial pacemaker implantation.
期刊介绍:
The mission of the Journal of Veterinary Cardiology is to publish peer-reviewed reports of the highest quality that promote greater understanding of cardiovascular disease, and enhance the health and well being of animals and humans. The Journal of Veterinary Cardiology publishes original contributions involving research and clinical practice that include prospective and retrospective studies, clinical trials, epidemiology, observational studies, and advances in applied and basic research.
The Journal invites submission of original manuscripts. Specific content areas of interest include heart failure, arrhythmias, congenital heart disease, cardiovascular medicine, surgery, hypertension, health outcomes research, diagnostic imaging, interventional techniques, genetics, molecular cardiology, and cardiovascular pathology, pharmacology, and toxicology.
