The seventh annual Gordon K. Moe Lecture. Atrial fibrillation: from cell t bedside.

abstract：INTRODUCTION:The purpose of this study is to describe a simple and reliable diagnostic maneuver that allows for the rapid differentiation of atypical AV nodal reentrant tachycardia (AVNRT) from other causes of long RP tachycardia. Long RP tachycardias may be caused by atypical AVNRT, orthodromic reciprocating tachycard...
