Conclusion

A smartphone-operated, 1L-ECG device is a reliable instrument for detecting AF when assessed by the internal detection algorithm, and even more so when assessed by cardiologists. Moreover, the 1L-ECG recording can display atrial and ventricular ectopy with high sensitivity. The 1L-ECG recording was less robust for detecting conduction delays. Our primary care–based study provides important insights for physicians who are in need of a point-of-care ECG device that can lower the logistical threshold for performing ECG to improve diagnostic gain.
