Implantable loop recorders (ILRs) are increasingly used in equine cardiology to detect arrhythmias in the context of collapse, poor performance or monitoring for recurrence of atrial fibrillation (AF). However to date, the ILR has never been reported to be used with a remote monitoring functionality in horses, therefore the arrhythmia is only discovered when a clinician interrogates the ILR using dedicated equipment, which might delay diagnosis and intervention. This case report describes the use of an ILR with remote monitoring functionality in a horse with recurrent AF. The remote monitoring consisted of a transmission device located in the stable allowing daily transmission of arrhythmia recordings and functioning messages to an online server, available for the clinician to evaluate without specialised equipment. The ILR detected an episode of paroxysmal AF approximately three months after implantation. Seven months after implantation, initiation of persistent AF was seen on an episode misclassified by the ILR as bradycardia, and the horse was retired. This report shows the feasibility and benefits of remote monitoring for ILRs in horses, but also the shortcomings of current algorithms to interpret the equine electrocardiogram.

使用具有远程监控功能的植入式循环记录仪检测马持续性心房颤动之前的阵发性心房颤动

植入式循环记录仪 (ILR) 越来越多地用于马心脏病学，以检测崩溃、表现不佳或监测心房颤动 (AF) 复发情况下的心律失常。然而迄今为止，尚未有报道称 ILR 在马身上使用远程监控功能，因此只有当临床医生使用专用设备询问 ILR 时才会发现心律失常，这可能会延误诊断和干预。本病例报告描述了具有远程监控功能的 ILR 在患有复发性 AF 的马身上的使用。远程监控由位于马厩中的传输设备组成，可以每天将心律失常记录和功能消息传输到在线服务器，临床医生无需专门设备即可进行评估。 ILR 在植入后大约三个月检测到阵发性 AF 发作。植入七个月后，在一次被 ILR 错误分类为心动过缓的发作中观察到持续性房颤的开始，这匹马被退役。该报告展示了远程监测马 ILR 的可行性和优势，但也指出了当前解释马心电图算法的缺点。
