Objective: To evaluate the psychometric properties of the Spanish version of the "FETCH-Q™" Animals Two hundred forty dogs with cardiovascular diseases and no comorbidities. Methods: After forward and back translation, the content validity was evaluated through feedback from veterinary colleagues. For convergent validity, the total score was correlated with the heart disease/failure (ISACHC) class. For construct validity, the overall quality of life of the dog and the results obtained in each item was correlated. The reliability of the questionnaire was assessed using the Cronbach’s alpha test. To evaluate the test-retest validity the intra-class correlation coefficient and Wilcoxon rank test were used to analyze the changes in total score of dogs that were reexamined. Results: A good agreement with the original questionnaire was evident. The face and content validity was appropriate. For construct validity, the questionnaire obtained r > 0.096 to < 0.82; (p<0.05). The convergent validity was appropriate and the correlation was r = 0.819 (p<0.001). Cronbach's alpha test was (α = 0.887) showing an appropriate internal consistency. The test-retest evaluation revealed adequate repeatability (ICC = 0.87; p <0.001). There was no difference in the owner responses to the questionnaire at baseline and two weeks later (p>0.05) in dogs that had stable cardiac disease. The mean and standard deviation (SD) of patients with the maximum score obtained was 3.5 ± 1.5. The mean and SD of patients with the minimum score obtained was 7 ± 2.4. Conclusion: This study supports the conclusion that this Spanish version of the functional evaluation of cardiac health questionnaire “FETCHSV2-Q” to assess HRQoL in dogs with cardiovascular disease is valid.

Background: Comparisons between smartphone ECG (SpECG) recordings obtained from the right and left sides of the thorax have not been reported in animals. Objectives: To evaluate the screening potential of a SpECG obtained from both sides of the thorax and to compare the degree of agreement between the SpECG and a reference ECG (rECG) for measurement of the duration of baseline electrical deflections recorded over both sides of the thorax. Animals: Fifty horses admitted to the equine hospital, university-owned horses, and horses from an endurance riding facility. Methods: Prospective observational study. Simultaneous rECG and SpECG tracings were recorded on both sides of the thorax and evaluated by 2 experienced observers for interpretability, presence and classification of arrhythmias, and duration of deflections of the electrical baseline. Results: Fifteen (15/50) horses had spontaneous arrhythmias. Excellent agreement was found between the 2 devices (κ = 0.91; P < .001; 95% confidence interval [CI] 0.79-1.03) for the detection of arrhythmias. Significantly more P waves were of diagnostic quality from the right side (20 versus 5, P = .001) and significantly more QRS and QT intervals were of diagnostic quality from the left side (66 versus 38 and 62 versus 34, respectively, P < .001). Substantial agreement for the duration of deflections between devices only was observed for the QRS interval (SpECG left). Conclusions and Clinical Importance: It is important to obtain SpECG tracings from both sides of the thorax in horses. The SpECG is a useful stall-sidearrhythmiascreening tool for some common arrhythmias in horses.
