Article Title: Comparison between smartphone electrocardiography and standard three-lead base apex electrocardiography in healthy horses

doi: 10.1136/vr.105759

Figure Lengend Snippet: Fleiss’s kappa agreement between three observers for categorical variables over all measurements, and either the smartphone-based method (AliveCor (AC)) or gold standard base-apex method (Televet (TV)) for all 15 horses

Article Snippet: The authors demonstrate that 1) the AliveCor-002 handheld smartphone ECG device was well tolerated by all horses; 2) at least 15 seconds of interpretable ECG tracing could be obtained from the AliveCor by recording the ECG for up to 45 seconds and visualised using the AliveECG application on an iPad mini; 3) there was moderate to good correlation between the AliveCor and Televet, and good correlation between observers correlation for the identification of the presence of benign arrhythmias; 4) correlation between the AliveCor and Televet varied from no correlation to very good, while correlation between observers was moderate to very good for the measurement of HR, P-wave and QRS duration, and PR, RR, QT and TT intervals; 5) 100 per cent of AliveCor HR measurements were within one measurement (4 bpm) of the median Televet HR and 6) 50 per cent–100 per cent of AliveCor P-wave and QRS duration, RR and QT interval measurements were within 5 per cent of the corresponding median Televet measurement; and 47 per cent and 7 per cent of AliveCor PR and TT interval measurements, respectively were within 5 per cent of the corresponding median Televet measurement.
