Abstract

The present case details an interesting intracardiac electrogram in a patient who demonstrated recurrent episodes of narrow complex tachycardia and who was subsequently found to have a typical atrioventricular nodal reentrant tachycardia during an electrophysiology study. The patient subsequently underwent slow pathway ablation and was found to be noninducible for any tachycardia after ablation.

摘要

本病例详细介绍了一名患者有趣的心内电图，该患者表现为反复发作的窄QRS波心动过速，随后在电生理研究中发现患有典型房室结折返性心动过速。该患者随后接受了慢径路消融，消融后未诱发出任何心动过速。
