During a median follow-up period of @ days ( interquartile range : @ to @,@ days ) , compared to FIRM-blinded therapy , patients receiving FIRM-guided ablation maintained higher freedom from AF after @ @ procedures ( median @ ; interquartile range : @ to @ ) ( @ % vs. @ % , p = @ ) and a single procedure ( p < @ ) and higher freedom from all atrial arrhythmias ( p = @ ) .
