Symptomatic premature atrial contractions (PACs) may be a target for catheter ablation. However, mapping of PACs with an atrial origin may not be easy because of erratic incidence and different sites of origin. Although the technique and efficacy of electroanatomic mapping has been established in stable arrhythmias, electroanatomic mapping of PACs in intermittent arrhythmias has not yet been reported. This article describes a manoeuvre for mapping PACs using an electroanatomic mapping system. Our experience has demonstrated that electroanatomic mapping using an auto-freeze map is feasible during PACs and may be an option for catheter ablation of PACs.
