“…This nding may be attributed to inherent di culty in maintaining optimal contact of electrodes with skin when using the smartphone-based device compared to the digital telemetric ECG device. However, the device allowed identi cation of normal sinus rhythm in all foals, and, in contrast to ndings from previous studies in sheep and goats (Smith 2020; King et al 2023), our results show a substantial agreement between rECG and sECG tracing quality.…”

Smartphone-based technology for ECG recording has recently spread as a complementary tool for electrocardiographic screening and monitoring in adult horses and in other animal species. The present study aimed to assess the feasibility and accuracy of a smartphone-based ECG in healthy foals. This was a prospective observational study (authorization n. 45865/2016) including 22 foals aged less than 21 days. A reference standard base-apex ECG (rECG) was acquired, and a smartphone ECG (sECG) was recorded immediately after by using a smartphone-based single lead electrocardiograph. All ECG tracings were evaluated in a blind fashion by a single board-certified cardiologist, who judged whether the tracings were acceptable for interpretation and performed ECG measurements and diagnosis. The Spearman correlation coefficient, the Cohen’s k test and the Bland-Altman test were used to assess the agreement between sECG and rECG. All sECG tracings were acceptable for interpretation. All foals showed sinus rhythm on both rRCG and sECG tracings, with perfect agreement in heart rate classification (κ = 0.87; p < 0.001). No clinically relevant differences were found in the assessment of waves and intervals duration. Concerning P wave and QRS complex polarity, the percentage of agreement between rECG and sECG was 78% and 83%, respectively. About ECG tracing quality, rECG and sECG showed a substantial agreement (κ = 0.624; p < 0.001). In conclusion, the smartphone-based ECG device tested in the present study recorded good quality single-lead ECG tracings in foals, reliable for heart rate and ECG measurements, but different polarity of P waves and QRS complexes was found in some foals in comparison to rECG.

“…Moreover, consistent with studies in small ruminants (Smith 2020 ; King et al 2023 ), the quality of sECG traces was found to be lower than those of rECG traces. This finding may be attributed to inherent difficulty in maintaining optimal contact of electrodes with skin when using the smartphone-based device compared to the digital telemetric ECG device.…”

“…The differences may be related to a certain restlessness of foals when handled as compared to adult animals. In a study assessing feasibility of smartphone-based ECG recording in sheep, a lower percentage of interpretability was found (65%) (King et al 2023 ), reasonably because of the feral temperament of the animals enrolled in the study.…”

“…All ECGs were quality scored on the basis of the presence or absence of baseline undulation and tremor artifacts using a 3-point scoring system previously described (King et al 2023 ). Briefly, score 0 = high-quality recording with no baseline wander or small baseline deflections; score 1 = Intermittent, mild tremors or baseline deflections or mild baseline wander; score 2 = Moderate tremors or baseline deflection consistent throughout the recording; score 3 = severe tremor artifact inhibiting the interpretation of the P and T waves.…”

“…Wireless, smartphone-based technology for ECG recording has recently spread as a complementary tool for electrocardiographic screening and monitoring in horses (Vezzosi et al 2018 ; Kraus et al 2019 ; Alberti et al 2020 ; Welch-Huston et al 2020 ; Vitale et al 2021 ), sheep (King et al 2023 ), dairy cows (Bonelli et al 2019 ), goats (Smith 2020 ), dogs and cats (Vezzosi et al 2016 ; Kraus et al 2016 ). In human medicine, smartphone-based one-lead ECG devices have been developed using specific adaptors and software (Saxon et al 2013; Ho et al 2014 ; Haberman et al 2015 ; Nguyen et al 2015 ; Tarakji et al 2015 ).…”
