PR interval associated genes, atrial remodeling and rhythm outcome of catheter ablation of atrial fibrillation-A gene-based analysis of GWAS data
Background: PR interval prolongation has recently been shown to associate with advanced left atrial remodeling and atrial fibrillation (AF) recurrence after catheter ablation. While different genome-wide association studies (GWAS) have implicated 13 loci to associate with the PR interval as an AF endophenotype their subsequent associations with AF remodeling and response to catheter ablation are u
