Objetivos  Nossa pesquisa teve como objetivo avaliar par\u00e2metros cl\u00ednicos, eletrocardiogr\u00e1ficos, laboratoriais e ecocardiogr\u00e1ficos que podem predizer a propens\u00e3o \u00e0 fibrila\u00e7\u00e3o atrial parox\u00edstica (FAP).  M\u00e9todos  Inscrevemos setenta e cinco pacientes ESUS que estavam em ritmo sinusal no momento do diagn\u00f3stico de acidente vascular cerebral para serem submetidos a monitoramento Holter de 7 dias no hospital, teste para Pro-BNP e um exame ecocardiogr\u00e1fico padr\u00e3o. Para an\u00e1lise estat\u00edstica, um valor de P &lt; 0,05 foi considerado significativo.  Resultados  A idade m\u00e9dia dos 75 pacientes ESUS foi de 58 anos. 60% dos pacientes eram do sexo masculino, e a condi\u00e7\u00e3o concomitante mais prevalente foi hipertens\u00e3o (53,3%). Quarenta pacientes tinham cardiopatia atrial, e 15 pacientes tiveram epis\u00f3dios de FAP. Hipertens\u00e3o e E\/e- &gt; 12 foram preditores independentes de cardiopatia atrial, com valores de p de 0,001 e 0,02, respectivamente. Em pacientes com cardiopatia atrial, foi realizada an\u00e1lise de regress\u00e3o multivari\u00e1vel; velocidade de for\u00e7a terminal da onda P na deriva\u00e7\u00e3o V (PTFV) &gt; 5000 mV.ms, \u00edndice de volume do \u00e1trio esquerdo &gt; 34 ml\/m2 e fra\u00e7\u00e3o de eje\u00e7\u00e3o &lt; 45% foram preditores independentes significativos de FA com valores de p significativos de 0,001, &lt; 0,001 e 0,001, respectivamente.  Conclus\u00f5es  Em pacientes ESUS, a cardiopatia atrial foi prevalente. Hipertens\u00e3o e uma raz\u00e3o E\/e- maior que 12 foram preditores independentes para ela. A an\u00e1lise de regress\u00e3o multivari\u00e1vel identificou PTFV1 &gt; 5000 mV.ms, \u00edndice de volume de AE &gt; 34 ml\/m2 e fra\u00e7\u00e3o de eje\u00e7\u00e3o &lt; 45% como preditores
