Summary. Objectives. The aim of the study was to study some anatomic and electrophysiological features of the right atrium, related to the presence of atrial flutter. Materials and methods. A total 23 patients with type I atrial flutter and 22 patients without atrial flutter were studied. Right atrium size was assessed using echocardiography before intracardiac examination and radiofrequency ablation. Results. Effective refractory periods of coronary sinus, high right atrium, low right atrium were different comparing with the control group (P
