Abstract
|
|
|
|
28-year-old man was admitted to our institution because of recurrent palpitation. He had had frequent premature atrial contraction and atrial tachycardia for 4 years. His atrial tachycardia was refractory to bisoprolol and flecainide; hence, he was referred for electrophysiological study and catheter ablation. Atrial tachycardia was consistently induced spontaneously or with rapid atrial pacing. Intracardiac electrograms and a 3-dimensional mapping system showed atrial tachycardia from the right atrial posterior wall. The earliest atrial activation was found with a remote magnetic navigation system. Radiofrequency energy was applied at the target region, successfully terminating the atrial tachycardia.
