Effective and fast characterization of a complex atrial flutter in patient with previous atrial surgery and ablation procedure: The importance of new ultra–high‐density mapping tools

Abstract

Abstract New tools of mapping systems may allow to detect residual conduction around the atriotomy and could eliminate the subjectivity of the human eye, analyzing thousands of electrograms in a matter of seconds and providing a clear and fast identification.
