摘要：

We describe a patient with frequent episodes of unusual paroxysmal supraventricular tachycardia. During the electrophysiological examination, the tachycardia was easily induced and terminated by atrial pacing. The earliest activation during right atrial. activation mapping was located near the atrioventricular node and the His bundle. However, detailed mapping of the aortic root demonstrated that the local activation in the non-coronary aortic cusp preceded the activation at the His bundle region. Radiofrequency catheter ablation at this site terminated the tachycardia with no complications.
