Geographic location of data collection (where was data collected?): University of Minnesota, St. Paul Campus 6. Information about funding sources that supported the collection of the data: This research was funded by Cardiac Insight; Morris Animal Foundation fellowship (D20EQ-403: SDA salary support); and a K12 award supported by 1UM1TR004405-01A1 Blazar (PI) and K12TR004373 Ingbar (PI) 7. Overview of the data (abstract): Background. Arrhythmias can cause poor performance and sudden death in horses. Long-term (>24 hours) electrocardiogram (ECG) monitoring has been used to identify arrhythmias in humans and is superior to short-term monitoring for transient arrhythmia detection. The Televet is the equine gold-standard ECG device, but Televet software is less useful for long-term monitoring. The Cardea SOLOTM (CS) is a single-use monitor with automated ECG analysis software allowing for ECG monitoring for 7 days. Objective. Our objective was to validate the performance of the CS and compare it to the equine gold-standard Televet device. Study design. ECGs were performed on 12 healthy horses simultaneously using both devices for 24 hours on day 1 and day 7, with the CS left in place for all seven days. Bland-Altman analysis and intraclass correlation were performed to test for agreement between the two devices for standard ECG measurements performed on both ECG traces. Results. The two devices identified similar numbers of arrhythmias. The correlation between devices for ECG measurements ranged from moderate to excellent. The CS recorded and analyzed ECGs for up to 7-days without adverse effects in all horses. The proportion of readable ECG decreased over time. Limitations. The major limitation of our study is the relatively small sample size (n=12), which may limit the generalizability of our findings and the challenge in identifying the same start time using both devices led to only eight horses being included in the device measurement comparisons. Additionally, it was not possible to evaluate the utility of the modified Cardea SOLO for detection of pathological arrhythmias. Conclusions. This study demonstrates the CS utility for long-term ECG monitoring and screening for arrhythmias in healthy horses. CS utility for the detection of pathological arrhythmias requires further investigation. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.
