ABSTRACT

Background:

Boxer dog cardiomyopathy was initially described by Neil Harpster in 1983 and has received different names. However, several recent studies demonstrated a similarity to the human arrhythmogenic right ventricular cardiomyopathy (ARVC), which led to the name Boxer ARVC. This hereditary disease seems to be linked to a mutation in the gene that codifies the cardiac ryanodine receptor. This mutation leads to an alteration of the calcium cycle in the heart. The analysis of the heart rate variability is an important predictive factor for diagnosing this disease. Therefore, this study aims to report a case of a Boxer ARVC providing electrocardiographic data and heart rate variability.Case A 11 year-old male Boxer dog, weighting 29.65 kg, was submitted to a heart check-up due to sudden occurrence of fatigue and syncope. At the clinical examination, heart auscultation did not revealed sounds or arrhythmias. The electrocardiogram results presented tachycardia and a regular rhythm with ventricular premature complexes (VPC´s). Ecodopplercargiogram was performed and values were within normal standards. Thus, a dynamic monitoring of 24 h was performed using a Holter monitor. This analysis demonstrated tachycardia in the sinus rhythm, type I second degree sinoatrial block, normal PR interval and normal length of QRS complexes. In addition, severe ventricular ectopy was identified in the following forms isolated, paired, and nonsustained ventricular tachycardia. The heart rate variability analysis resulted in mean values of 213 ms (SNDD), 132 ms (SDANN), 211ms (rMSSD) and 33.46% (pNN50). Based on these data, Boxer ARVC is the probable diagnosis. However, a ventricular myocardial biopsy necessary to confirm the disease was not performed due to the inherent risk of the procedure. Treatment was performed with sotalol and a commercial feed specially designed for dogs with for cardiac diseases.[...](AU)
