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.

心外膜起搏器植入一只患有病态窦性综合征的年轻猫。
一只一岁的阿比西尼亚猫被认为是空虚,夸张的眨眼和间歇性崩溃的发作。12导联心电图(ECG)和心电图遥测显示窦性心动过缓,窦性暂停,窦性骤停伴交界性逸出节律。在全身性疾病筛查期间,未发现感染性病原体是导致慢性心律失常的原因。结果与特发性病窦综合征一致。茶碱治疗没有改善临床症状或心电图表现。放置心外膜起搏器,减轻了临床症状。起搏器植入后的询问显示起搏器很少使用。本病例报告强调了心电图遥测在描述有临床症状的猫的窦性停搏、交界性逸出节律和窦性心动过缓的心电图表现方面的应用,这些症状与病态窦性综合征一致,在心外膜起搏器植入后消失。

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.
