摘要：
The aim of this study was to define atrial electrograms (EGM) morphology, which could predict a conduction gap in cavo-tricuspid isthmus (CTI) during typical atrial flutter (AF) radiofrequency ablation. One hundred atrial EGM were retrospectively analysed. We demonstrated that recognising a sharp potential (short duration and high amplitude) is useful for quickly achieving CTI bi-directional block during typical AF ablation.
