Arritmia cardíaca: fibrilação atrial

Otávio Ayres da Silva Neto

Resumo


A fibrilação atrial é a alteração supraventricular do ritmo cardíaco mais comum e com uma incidência elevada progressivamente relacionada às idades mais avançadas. Existe um remodelamento atrial com mudanças estruturais (alargamento e fibrose intersticial), que promovem a desorganização rítmica. O tratamento farmacológico ou invasivo por cateteres visa a prevenção das complicações tromboembólicas e a evolução para taquicardiomiopatia numa tentativa de melhorar a qualidade de vida e reduzir a morbimortalidade.
