This issue is particularly relevant in cancer survivors, whose thrombotic and bleeding risks vary according to cancer activity, treatment exposure, thrombocytopenia, frailty and planned procedures. For this narrative review, PubMed\/MEDLINE and Scopus were searched from inception to 16 June 2026, with Google Scholar used for supplementary citation tracking. A total of 50 publications were included in the final narrative synthesis. Direct evidence at the intersection of cancer, cardiac surgery, POAF and digital monitoring remains limited. Accordingly, the proposed \u201cDigital Cancer-POAF Survivorship Pathway\u201d is presented as a conceptual, hypothesis-generating framework, rather than a validated clinical algorithm. Its distinctive contribution is to connect cancer-state phenotyping and treatment-specific arrhythmic risk with post-discharge rhythm surveillance, electrocardiogram (ECG) confirmation, multidisciplinary interpretation, data governance and outcomes for prospective validation. Digital monitoring may increase AF detection; however, whether it reduces stroke, bleeding, readmission, or healthcare utilisation in this population is unknown. Neither a low detected AF burden nor the absence of AF during finite monitoring has been validated as an independent basis for anticoagulation decisions.<\/jats:p>","DOI":"10.3390\/medicina62081597","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T08:10:20Z","timestamp":1787213420000},"page":"1597","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Digital Rhythm Surveillance After Postoperative Atrial Fibrillation in Cancer Survivors: A Cardio-Oncology Survivorship Pathway"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2259-5004","authenticated-orcid":false,"given":"Sotiris","family":"Kyriakou","sequence":"first","affiliation":[{"name":"Barts and The London School of Medicine and Dentistry, Queen Mary University of London, London EC1M 6BQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1667-3172","authenticated-orcid":false,"given":"Georgios P.","family":"Georghiou","sequence":"additional","affiliation":[{"name":"Department of Surgery, Gray Faculty of Medical & Health Sciences, Tel Aviv University, Tel Aviv 6997801, Israel"},{"name":"School of Medicine, European University Cyprus,  Nicosia 2404, Cyprus"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7523-9786","authenticated-orcid":false,"given":"Panos","family":"Georghiou","sequence":"additional","affiliation":[{"name":"Barts and The London School of Medicine and Dentistry, Queen Mary University of London, London EC1M 6BQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7531-9580","authenticated-orcid":false,"given":"Argyris","family":"Kyriakou","sequence":"additional","affiliation":[{"name":"Barking, Havering and Redbridge University Hospitals NHS Trust, London RM7 0AG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amalia","family":"Georgiou","sequence":"additional","affiliation":[{"name":"Krankenhaus Maria Hilf Krefeld, 47805 Duseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marilina","family":"Neokleous","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Cyprus, Nicosia 2029, Cyprus"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9439-3946","authenticated-orcid":false,"given":"Andrew","family":"Xanthopoulos","sequence":"additional","affiliation":[{"name":"School of Medicine, European University Cyprus,  Nicosia 2404, Cyprus"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6433-4016","authenticated-orcid":false,"given":"Filippos","family":"Triposkiadis","sequence":"additional","affiliation":[{"name":"School of Medicine, European University Cyprus,  Nicosia 2404, Cyprus"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4","DOI":"10.1016\/j.cvdhj.2020.11.004","article-title":"2021 ISHNE\/HRS\/EHRA\/APHRS Collaborative Statement on mHealth in Arrhythmia Management: Digital Medical Tools for Heart Rhythm Professionals: From the International Society for Holter and Noninvasive Electrocardiology\/Heart Rhythm Society\/European Heart Rhythm Association\/Asia Pacific Heart Rhythm Society","volume":"2","author":"Varma","year":"2021","journal-title":"Cardiovasc.
