AbstractFocal atrial tachycardia (AT) though a relatively uncommon cause of supraventricular
tachycardia is difficult to control with antiarrythmic drugs. With the advent of radiofrequency
ablation (RFA), this form of tachycardia can be treated with high long-term success . These
foci tend to cluster at specific anatomic locations. In the right atrium, these foci occur along the
crista terminalis, the tricuspid annulus, the ostium of the coronary sinus and the perinodal region.
In the left atrium, foci occur predominantly at the pulmonary vein ostia and less commonly at
the mitral annulus, the left atrial appendage, and the left side of interatrial septum [2-6].
We report the electrophysiological characteristics and ablation procedure of a focal atrial
tachycardia which was arising from deep within the coronary sinus.
