In the majority of cases, the cause is considered to be a malignant ventricular tachyarrhythmia, which can be precipitated by a number of underlying pathologies. Conversely, a tachyarrhythmia may have a more benign and treatable cause, yet the initial clinical symptoms may be similar, making differentiation difficult. This is an overview of the mechanisms underlying the initiation and propagation of arrhythmias and the various pathological conditions that predispose to arrhythmia genesis, classified according to which parts of the heart are involved: atrial tachyarrhythmias, atrial and ventricular, as well as those affecting the ventricles alone. It encompasses atrial tachycardia, atrial flutter, supraventricular tachycardias and ventricular tachycardias, including the more commonly encountered inherited primary electrical diseases, also known as the channelopathies. The clinical features, investigation and management strategies are outlined. The occupational impact\u2014in serving military personnel and potential recruits\u2014is described, with explanations relating to the different conditions and their specific implication on continued military service.<\/jats:p>","DOI":"10.1136\/jramc-2015-000494","type":"journal-article","created":{"date-parts":[[2015,8,5]],"date-time":"2015-08-05T22:00:13Z","timestamp":1438812013000},"page":"244-252","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Atrial and ventricular tachyarrhythmias in military personnel"],"prefix":"10.1136","volume":"161","author":[{"given":"Bonnie N","family":"Posselt","sequence":"first","affiliation":[{"name":"Defence Medical Services, Royal Centre for Defence Medicine, Birmingham, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A T","family":"Cox","sequence":"additional","affiliation":[{"name":"Defence Medical Services, Royal Centre for Defence Medicine, Birmingham, UK"},{"name":"Department of Cardiology, St George's, University of London, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"D'Arcy","sequence":"additional","affiliation":[{"name":"Defence Medical Services, Royal Centre for Defence Medicine, Birmingham, UK"},{"name":"Department of Cardiology, RCDM (Oxford), John Radcliffe Hospital, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Rooms","sequence":"additional","affiliation":[{"name":"Regional Occupational Health Team (North), Catterick Garrison, North Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Saba","sequence":"additional","affiliation":[{"name":"Regional Occupational Health Team (North), Catterick Garrison, North Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,8,5]]},"reference":[{"key":"2025081306391832000_161.3.244.1","doi-asserted-by":"publisher","DOI":"10.1136\/jramc-131-01-10"},{"key":"2025081306391832000_161.3.244.2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-141-11-200412070-00005"},{"key":"2025081306391832000_161.3.244.3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1161\/01.RES.49.1.1","article-title":"Cellular mechanisms for cardiac arrhythmias","volume":"49","author":"Hoffman","year":"1981","journal-title":"Circ Res"},{"key":"2025081306391832000_161.3.244.4","doi-asserted-by":"publisher","DOI":"10.1136\/jramc-2015-000505"},{"key":"2025081306391832000_161.3.244.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(00)00700-2"},{"key":"2025081306391832000_161.3.244.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00422-1"},{"key":"2025081306391832000_161.3.244.7","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(98)80312-4"},{"key":"2025081306391832000_161.3.244.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.cpcardiol.2005.06.004"},{"key":"2025081306391832000_161.3.244.9","doi-asserted-by":"publisher","DOI":"10.1053\/euhj.1998.1313"},{"key":"2025081306391832000_161.3.244.10","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/14.12.1654"},{"key":"2025081306391832000_161.3.244.11","doi-asserted-by":"crossref","first-page":"563","DOI":"10.1016\/0002-9149(86)90836-2","article-title":"Tachycardia-induced cardiomyopathy: a reversible form of left ventricular dysfunction","volume":"57","author":"Packer","year":"1989","journal-title":"Am J Cardiol"},{"key":"2025081306391832000_161.3.244.12","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.86.4.1138"},{"key":"2025081306391832000_161.3.244.13","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.90.3.1262"},{"key":"2025081306391832000_161.3.244.14","doi-asserted-by":"publisher","DOI":"10.1136\/heart.84.2.227"},{"key":"2025081306391832000_161.3.244.15","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.50.1.92"},{"key":"2025081306391832000_161.3.244.16","doi-asserted-by":"crossref","first-page":"841","DOI":"10.1111\/j.1540-8159.1996.tb03368.x","article-title":"Arribas, atrial flutter mapping and ablation","volume":"19","author":"Cosio","year":"1996","journal-title":"PACE"},{"key":"2025081306391832000_161.3.244.17","doi-asserted-by":"crossref","first-page":"1069","DOI":"10.1136\/hrt.37.10.1069","article-title":"\u2018Dual atrioventricular nodal pathways.
