Descrever os n\u00edveis de AF e as barreiras percebidas, bem como avaliar suas associa\u00e7\u00f5es com o fen\u00f3tipo de arritmia e a QV em pacientes ambulatoriais de n\u00edvel terci\u00e1rio com fun\u00e7\u00e3o do ventr\u00edculo esquerdo (VE) preservada, se faz necess\u00e1rio. Este \u00e9 um estudo piloto, transversal, que incluiu adultos com arritmias documentadas e fra\u00e7\u00e3o de eje\u00e7\u00e3o do VE (FEVE) \u2265 50%. A AF foi avaliada por meio da vers\u00e3o curta do International Physical Activity Questionnaire (IPAQ), e a QV pelo 12-Item Short Form Survey (SF-12). As arritmias foram classificadas como taquicardia supraventricular (TSV), fibrila\u00e7\u00e3o atrial (FA) e\/ou taquicardia atrial (TA) (incluindo flutter atrial quando aplic\u00e1vel), ventricular, heredit\u00e1ria ou m\u00faltipla. As associa\u00e7\u00f5es foram analisadas por meio de testes do qui-quadrado, regress\u00e3o multinomial e modelos de regress\u00e3o linear. Entre 202 participantes (idade m\u00e9dia 50,5 \u00b1 15,3 anos; 58,9% homens), 20,3% eram sedent\u00e1rios e 45,6% eram ativos ou muito ativos. A preval\u00eancia de comportamento sedent\u00e1rio foi maior entre pacientes com arritmias ventriculares (25,9%), arritmias heredit\u00e1rias (35,1%) e arritmias m\u00faltiplas (25,0%) em compara\u00e7\u00e3o com aqueles com TSV (3,8%) e FA\/TA (8,0%) (p = 0,043). Nos modelos ajustados, n\u00edveis de AF ativos ou muito ativos mostraram uma tend\u00eancia a escores mais elevados no componente f\u00edsico do SF-12 (p = 0,08), enquanto os escores do componente mental foram principalmente influenciados pelo status dos sintomas e pelo sexo. Nesta coorte ambulatorial terci\u00e1ria com arritmias e FEVE preservada, a inatividade f\u00edsica concentrou-se em fen\u00f3tipos de maior risco e esteve frequentemente associada a barreiras potencialmente modific\u00e1veis, incluindo orienta\u00e7\u00e3o m\u00e9dica e falta de tempo. N\u00edveis mais elevados de AF tenderam a estar associados a melhor estado de sa\u00fade f\u00edsica, sustentando a necessidade de aconselhamento individualizado baseado no risco e de estrat\u00e9gias supervisionadas para promover de forma segura a AF em pacientes com arritmias.<\/jats:p>","DOI":"10.36660\/abc.20250831","type":"journal-article","created":{"date-parts":[[2026,7,23]],"date-time":"2026-07-23T19:10:56Z","timestamp":1784833856000},"source":"Crossref","is-referenced-by-count":0,"title":["N\u00edveis de Atividade F\u00edsica e Qualidade de Vida em Pacientes Ambulatoriais com Arritmias Card\u00edacas e Fun\u00e7\u00e3o Ventricular Esquerda Preservada: Compreendendo Seu Perfil"],"prefix":"10.36660","volume":"123","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7815-3515","authenticated-orcid":false,"given":"Savia Christina Pereira","family":"Bueno","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patr\u00edcia Alves","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3088-972X","authenticated-orcid":false,"given":"M\u00e1rya","family":"Pagotti","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3679-5349","authenticated-orcid":false,"given":"Luciana","family":"Sacilotto","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabrielle D\u2019Arezzo","family":"Pessente","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6690-6345","authenticated-orcid":false,"given":"Pedro Gabriel Senger","family":"Braga","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aline L.","family":"Souza","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8070-6112","authenticated-orcid":false,"given":"Alexandra Regia Dantas","family":"Brigido","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil; Hospital Israelita Albert Einstein,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos E.","family":"Negr\u00e3o","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco C.
