Successful Catheter Cryoablation for Atrial Fibrillation in Patients with Permanent Cardiac Pace-maker Implants

In daily practice, several methods including electrocardiography, 24-hour Holter ECG monitoring, or event recorders are frequently used for diagnosis and follow-up of patients with atrial fibrillation (AF). Although these tests provide crucial information, they may be insufficient in selected cases. In this case, we utilized intracardiac electrocardiogram recordings for both diagnosis of AF and detection of its recurrence in a patient with a permanent pace-maker who underwent AF ablation because of symptomatic and asymptomatic paroxysmal AF episodes. Because patients with permanent pacemakers are continuously monitored via intracardiac recordings, we believe that it is the most definite method for both diagnosis and monitoring of treatment success
