In this lavishly illustrated atlas, a selection of very difficult cases of arrhythmias are presented, in whom correct diagnosis and successful ablation have been guided by the integration of conventional intracavitary signals and electroanatomic mapping (Carto technology). For each case a short introduction, procedure details and outcome, and a brief commentary are given. Throughout, the crucial role of electroanatomic mapping in providing unique information and new insights in a field still in evolution is very evident. Self-explanatory images and a step-by-step approach make the volume a "cook-book" to be read day by day. The book will prove to be very a useful tool for all the operators working in this field.
