Cardioversion electric in patients with atrial fibrillation and atrial flutter ; Cardioversão elétrica em pacientes com fibrilação atrial e flutter atrial

Objective: to evaluate the positioning of the cardioverter blades electrode for performing service to electrical cardioversion in patients with atrial fibrillation (AF) and atrial flutter (AFL). Method: quantitative study, cross-sectional, descriptive and analytical retrospective documentary base. Data were collected from medical records of patients, treated between January 1999 and January 2006. Data were analyzed using the Mann-Whitney, chi-square and Z tests. The research project was approved by the Research Ethics Committee, under protocol number 689. Results: the sample consisted of 79 patients with AF and 33 with AFL. The global response to the ECV was 91.1%. In the AF anterolateral approach, the proportion of successful assistance was 75% as opposed to 94.9% when performed with antero-posterior approach. In the AFL with anterolateral approach, success was complete, compared to the success rate of 92.9% of cases in anteroposterior approach. In patients with AF, the success of the initial shock of 200J was higher when performed in the anteroposterior approach. Conclusion: in cases of patients with AF, ECV held in anteroposterior position, they obtained greater success to anterolateral.

RESUMO Objetivo: avaliar o posicionamento das pás-eletrodo do cardioversor durante realização de atendimento com cardioversão elétrica em pacientes com fibrilação atrial (FA) e flutter atrial (FlA). Método: estudo quantitativo, transversal, descritivo e analítico, de base documental, retrospectivo. Os dados foram coletados a partir dos prontuários dos pacientes, atendidos entre janeiro de 1999 e janeiro de 2006. Os dados foram analisados com uso dos testes de Mann-Whitney, qui-quadrado e Z. O projeto de pesquisa foi aprovado pelo Comitê de Ética em Pesquisa, protocolo no. 689. Resultados: a amostra foi composta de 79 pacientes com FA e 33 com FlA. A resposta global à CVE foi de 91,1%. Na FA com abordagem anterolateral, a proporção de ...
