Cardiac arrhythmias as a cause of syncope, collapse, or intermittent weakness can be challenging to diagnose. The purpose of this paper is to retrospectively review the diagnosis and outcome of 23 cases of syncope or collapse in dogs that had a Reveal Plus ILR recorder placed as part of the diagnostic evaluation.
ANIMALS, MATERIALS AND METHODS: Medical records of 23 client-owned dogs that were presented for evaluation of syncope, collapse, or intermittent weakness were retrospectively reviewed.
Recurrent syncope occurred in 13/23 (57%) and a positive diagnosis of the cause of the event was made in 11/13 (48% of all dogs). Diagnoses included 6/11 with prolonged periods of sinus arrest with slow ventricular escape rate and one each of sub-optimal fixed heart rate by endocardial pacing, high grade second degree atrioventricular block, supraventricular tachycardia, normal ECG during multiple episodes, and high grade second degree atrioventricular block or sinus arrest.
The Reveal Plus ILR device was successful in diagnosing a high percentage of cases of syncope or collapse in which signs recurred and implantation had a low complication rate. The Reveal Plus ILR device is a useful tool to diagnose the etiology of recurrent syncope, collapse, or intermittent weakness in the dog.
心律失常作为晕厥、虚脱或间歇性虚弱的一个病因，其诊断可能具有挑战性。本文的目的是回顾性分析23例因晕厥或虚脱而植入Reveal Plus ILR记录仪作为诊断评估一部分的犬病例的诊断情况及结果。
动物、材料与方法：对23例因晕厥、虚脱或间歇性虚弱前来就诊的宠物犬的病历进行回顾性分析。
13/23（57%）的犬出现反复晕厥，其中11/13（占所有犬的48%）明确诊断出事件原因。诊断包括6/11为窦性停搏时间延长伴心室逸搏率缓慢，1例为心内膜起搏心率固定不理想，1例为高度二度房室传导阻滞，1例为室上性心动过速，多次发作时心电图正常，1例为高度二度房室传导阻滞或窦性停搏。
Reveal Plus ILR设备成功诊断出了高比例的反复出现症状的晕厥或虚脱病例，且植入并发症发生率低。Reveal Plus ILR设备是诊断犬反复晕厥、虚脱或间歇性虚弱病因的有用工具。
