Abstract/OtherAbstract:
BACKGROUND: Several clinical trials have shown inconsistent results regarding the effect of electrode positions on the success of electrical cardioversion.
AIMS: The aim of this meta-analysis was to investigate the effect of the anterior-posterior electrode position on the success of electrical cardioversion in patients undergoing external electrical cardioversion for atrial fibrillation.
METHODS: Pubmed, EMBASE, the Cochrane Library and the Chinese National Knowledge Infrastructure were searched for randomized controlled trials. The effect of the anterior-posterior electrode position on cardioversion success is presented as a risk ratio with 95% confidence interval.
RESULTS: Ten trials with 1281 patients were included in the analysis. The anterior-posterior electrode position had no advantages in terms of success of electrical cardioversion for atrial fibrillation compared with the anterior-lateral electrode position (risk ratio 1.02, 95% confidence interval 0.96-1.09; P=0.50). Subgroup analysis showed that patients with a left atrium diameter≤45mm and lone atrial fibrillation might derive benefits from the anterior-posterior electrode position in terms of success of cardioversion. No evidence of publication bias was detected.
CONCLUSIONS: The present analysis suggests that only patients with a left atrium diameter≤45mm and lone atrial fibrillation might derive benefits from the anterior-posterior electrode position compared with the anterior-lateral electrode position during external electrical cardioversion for atrial fibrillation. However, there was insufficient evidence to support any advantages for the anterior-posterior electrode position in other situations.
