Conventional Technique for Ablation of Upper Loop Reentry

Abstract: We present a 33 years-old smoker male with dyspnea on exertion, the cause of which was finally identified as atrial tachyarrhythmia after performing echocardiography, coronary angiography, right, and left sided cardiac catheterization During electrophysiology study; upper loop reentry (ULR) a rare form of atypical Atrial flutter was diagnosed and ablated by conventional technique. New mapping technology improved our understanding of the mechanism and pathways of arrhythmia, and allowed complex ablations made easier and more cost-effective.
