Abstract

The intracardiac electrograms are shown during scanned single premature ventricular extrastimuli with a decreasing coupling interval in a very short RP tachycardia. What is the diagnosis and is the fast pathway essential for sustaining the tachycardia?

Keywords: atrioventricular nodal reentrant tachycardia; bystander; fast pathway; slow pathway.
