The feasibility of the home monitoring of heart rate (HR) and rhythm through ECG tracings recorded by owners with a smartphone ECG device was evaluated in dogs. Smartphone ECG tracings were recorded by owners at home using a single-lead ECG device and sent via email for interpretation. A questionnaire was prepared to assess the owner’s opinion regarding this home monitoring service. Recordings were evaluated by two operators, and agreement was evaluated for HR and rhythm diagnosis. Thirty-three dogs were included. Thirty-one owners (94 per cent) felt that the recording technique was easy to learn and that the smartphone ECG device was easy to use. A total of 15 owners (45 per cent) required a second person to hold the dog during recording. Of the 150 smartphone ECG tracings that were received, 134 (89 per cent) were interpretable. The median difference between the two operators to assess the mean HR on the smartphone tracings was 10 bpm (−10, +25 bpm). Perfect agreement (κ=1) between operators was observed in the heart rhythm evaluation. Most owners sent adequate ECG tracings for interpretation via email from their smartphone. Home monitoring of HR and heart rhythm may represent an additional tool in the management of dogs with arrhythmias.
