Abstract
|
|
|
|
Most of supraventricular tachycardias (SVTs) are relatively easy to detect and get exact diagnosis with cardiac electrophysiological studies. In addition, catheter ablation has excellent outcome and high success rate of greater than 95%. However, it is still challenging for electrophysiologists in diagnosis and catheter ablation of unusual type of SVTs. Following topics are the scope of this review: ① accessory pathway with unusual electrophysiological or anatomical characteristics, and ② SVTs in congenital anomalies affecting catheter ablation procedures. Exact diagnosis and anatomical information would be the key components in successful ablation of unusual SVTs.
