In this issue of Cardiac Electrophysiology Clinics, guest editors Giuseppe Bagliani, Roberto De Ponti, and Fabio Leonelli bring their considerable expertise to the topic of the multifaced aspects of atrial flutter interpreted by precision electrocardiology. Top experts in the field teach readers to discriminate the different forms of atrial flutter based on surface electrocardiogram and intracavitary signals and to correctly approach this arrhythmia invasively by ablation. Readers will also learn the importance of the appropriate treatment in different patient populations.
