短P-R间期是临床上常见的一种心电图表现,传统诊断多认为是变异型预激综合征之L-G-L综合征群,近年来,随着心电生理学的不断发展和研究,对短P-R综合征的认识也发生改变,认为P-R间期缩短也可以是一种非传导异常所致。本文从我院近年来出现的这些现象进行分析,探讨引起P-R间期缩短 Short PR interval is a clinical manifestation of a common ECG, the traditional diagnosis of multiple variants of the LGW syndrome is considered pre-excitation syndrome, in recent years, with the continuous development of electrophysiology and research, the short-term PR syndrome Recognition also changed, think shortening PR interval can also be caused by a non-conduction abnormalities. This article from our hospital in recent years, these phenomena were analyzed to explore the cause of P-R interval shortening
