Plain-English summary

A group of six dogs that experienced unexplained collapse or fainting episodes were evaluated using implantable loop recorders, which monitor heart activity. One dog was diagnosed with a fast heart rhythm called supraventricular tachycardia, while two others were found to have conditions that could cause similar symptoms, including heart disease and epilepsy. One dog stopped collapsing after the diagnosis, while another did not receive a clear diagnosis, and one dog was lost to follow-up. This study suggests that implantable loop recorders can be a helpful tool for diagnosing the cause of collapse in dogs.

Abstract

Objective: The purpose of this study was to investigate whether implantable loop recorders could be used in the diagnosis of unexplained collapse in dogs. Methods: The medical records of six dogs presented to the University of Liverpool Small Animal Teaching Hospital between May 2003 and October 2006 for further evaluation of intermittent syncopal episodes, collapse or episodic weakness, were reviewed. All these dogs underwent standard investigations and had implantable loop recorders placed. Results: A provisional diagnosis of supraventricular tachycardia was made in one dog, and diagnoses of exclusion of arrhythmogenic right ventricular cardiomyopathy and idiopathic epilepsy was made in two dogs. One dog suffered no further syncopal episodes, a diagnosis was not reached in another dog and the final dog was lost to follow‐up. Clinical Significance: The implantable loop recorder can be used successfully for the diagnosis of unexplained collapse in dogs.
