2015 ACVIM Forum Research Abstract Program

Twenty-six dogs were evaluated and five were excluded due to an abnormal physical, historical, and/or clinicopathological finding. Twenty-one dogs were included. There were 14 spayed females and 7 castrated males, mean age was 9.2 AE 2.9 (range, 5.4 to 14.6) years, and mean body weight was 25.6 AE 11.1 kg. The mean UAldo:C was 0.49 lg/g, AE 0.27 and no dog had a UAldo:C greater than 1.0. The difference between the UAldo:C in this group of older dogs was not different from the younger, laboratory dogs (P = 0.2). These data were normally distributed. The reference interval was calculated to be (0.05 to 0.92 lg/g), (2.5 and 97.5% percentiles). The 90% confidence interval for the lower limit was (0 -0.084 lg/g), and for the upper limit (0.882 -1.23 lg/g). Although evaluation of more dogs is required to establish an exact reference interval, it can be seen that the UAldo:C rarely exceeds 1.0 lg/g in normal dogs and the UAldo: C does not appear to change significantly with age in normal dogs. Cardiac arrhythmias often are transient and might not be detected using conventional electrocardiography or 24-hour Holter monitoring. The ZIO Ã’ Patch (ZP; iRhythm Technologies, Inc, San Francisco, California) is a single-lead, lightweight, adhesive, 14-day ambulatory ECG monitor. This device, made for human patients, does not have external leads or wires, is singleuse, has a low-profile design, is water-resistant, and has a button that can be pressed to mark clinical events. This study aimed to prospectively assess the usability of this monitor in 4 Boxer dogs considered to be healthy or affected with arrhythmogenic right ventricular cardiomyopathy. The study consisted of 3 parts:
