Our aim in this work was twofold: First, we scrutinized the scope and limitations of existing methods for Holter monitoring when moving to long-term monitoring; Second, we proposed and benchmarked a beat detection method with adequate accuracy and usefulness in long-term scenarios. A longitudinal study was made with the most widely used waveform analysis algorithms, which allowed us to tune the free parameters of the required blocks, and a transversal study analyzed how these parameters change when moving to different databases. With all the above, the extension to long-term monitoring in a database of 7-day Holter monitoring was proposed and analyzed, by using an optimized simultaneous-multilead processing. We considered both own and public databases. In this new scenario, the noise-avoid mechanisms are more important due to the amount of noise that exists in these recordings, moreover, the computational efficiency is a key parameter in order to export the algorithm to the clinical practice. The method based on a Polling function outperformed the others in terms of accuracy and computational efficiency, yielding 99.48% sensitivity, 99.54% specificity, 99.69% positive predictive value, 99.46% accuracy, and 0.85% error for MIT-BIH arrhythmia database. We conclude that the method can be used in long-term Holter monitoring systems.<\/jats:p>","DOI":"10.3390\/s18051387","type":"journal-article","created":{"date-parts":[[2018,5,3]],"date-time":"2018-05-03T03:20:27Z","timestamp":1525317627000},"page":"1387","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["On the Beat Detection Performance in Long-Term ECG Monitoring Scenarios"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6916-6082","authenticated-orcid":false,"given":"Francisco-Manuel","family":"Melgarejo-Meseguer","sequence":"first","affiliation":[{"name":"Cardiology Service, Arrhythmia Unit, Hospital General Universitario Virgen de la Arrixaca, El Palmar, 30120 Murcia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7827-3197","authenticated-orcid":false,"given":"Estrella","family":"Everss-Villalba","sequence":"additional","affiliation":[{"name":"Cardiology Service, Arrhythmia Unit, Hospital General Universitario Virgen de la Arrixaca, El Palmar, 30120 Murcia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2727-2132","authenticated-orcid":false,"given":"Francisco-Javier","family":"Gimeno-Blanes","sequence":"additional","affiliation":[{"name":"Department of Signal Theory and Communications, Miguel Hern\u00e1ndez University, Elche, 03202 Alicante, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6593-1517","authenticated-orcid":false,"given":"Manuel","family":"Blanco-Velasco","sequence":"additional","affiliation":[{"name":"Department of Signal Theory and Communications, University of Alcal\u00e1, Alcal\u00e1 de Henares, 28805 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0166-9617","authenticated-orcid":false,"given":"Zaida","family":"Molins-Bordallo","sequence":"additional","affiliation":[{"name":"Cardiology Service, Arrhythmia Unit, Hospital General Universitario Virgen de la Arrixaca, El Palmar, 30120 Murcia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1310-3028","authenticated-orcid":false,"given":"Jos\u00e9-Antonio","family":"Flores-Yepes","sequence":"additional","affiliation":[{"name":"Department of Signal Theory and Communications, Miguel Hern\u00e1ndez University, Elche, 03202 Alicante, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0426-8912","authenticated-orcid":false,"given":"Jos\u00e9-Luis","family":"Rojo-\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Center for Computational Simulation, Universidad Polit\u00e9cnica de Madrid, Boadilla, 28223 Madrid, Spain"},{"name":"Department of Signal Theory and Communications, Rey Juan Carlos University, Fuenlabrada, 28943 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1928-865X","authenticated-orcid":false,"given":"Arcadi","family":"Garc\u00eda-Alberola","sequence":"additional","affiliation":[{"name":"Cardiology Service, Arrhythmia Unit, Hospital General Universitario Virgen de la Arrixaca, El Palmar, 30120 Murcia, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1016\/j.ijcard.2008.10.004","article-title":"Influence of the duration of Holter monitoring on the detection of arrhythmia recurrences after catheter ablation of atrial fibrillation Implications for patient follow-up","volume":"139","author":"Dagres","year":"2010","journal-title":"Int.
