Brief Summary
In this study a new technique for ablation in atrioventricular nodal reentrant tachycardia using cryo-energy will be studied in cases where the standard approach has higher risk.
Detailed Description
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common cause of fast heartbeats in young people. People with AVNRT have two pathways within the heart, the fast pathway (FP) and slow p...
