Abstract: Atrioventricular nodal reentrant tachycardia(AVNRT) with the left inferior extensions of the atrioventricular node being the substrates of the slow pathway is rare in clinical practice. In this case the left extension might serve as anterograde limbs and the left atrial working myocardium participated in the circuit. We expect to improve the diagnosis and treatment of difficult cases of AVNRT by discussing the exact location of reentry pathway and the ablation target zone and optimal end points. -
