Edvard Liljedahl Sandberg: The primary aim of this study was to evaluate the diagnostic accuracy and usability of ECG247 Smart Heart Sensor compared to conventional Holter monitoring. 
Patients > 18 years of age referred for out-of-hospital long-term ECG recording regardless of indication or symptoms were screened for inclusion. A total of 150 subjects with an average age of 54 were included. ECG247 and Holter-system were mounted and activated simultaneously, and the participants were instructed to wear both systems for a minimum of twenty-four (24) hours (mean parallel ECG-monitoring time was 33 hours). Results showed that ECG247 Smart Heart Sensor showed at least comparable diagnostic accuracy for AF and improved usability compared to conventional Holter technology. ECG247 allows for prolonged monitoring, and hence it may improve the detection of AF.
