目的探讨阵发性室上性心动过速(PSVT)不同折返类型的基础心脏病、年龄和性别差异。方法选择2008年5月-2010年5月浙医二院心内科收治的204例折返机制引发的PSVT作为研究对象,采用回顾性研究方法,探讨PSVT不同折返类型与基础心脏病、年龄和性别的关系,并对各型之间的差异进行分析。结果 AVNRT和AVRT多无器质性心脏病(占66例和91例,P>0.05),IART和SNRT以合并器质性心脏病多见(各7例,P>0.05),两两比较差异均有统计学意义(P<0.01);在年龄、性别差异上,AVNRT多见于非老年女性(占65.8%),AVRT多见于非老年男性(占46.4%),IART和SNRT以老年男性居多(占40.0%和44.4%)。结论 PSVT因折返机制不同,表现为不同的折返类型,各型在基础心脏病、年龄和性别上存在不同程度的差异。
Objective To investigate the underlying cardiac diseases, age and gender differences in patients with paroxysmal supraventricular tachycardia (PSVT). METHODS: From May 2008 to May 2010, 204 cases of PSVT induced by reentrant mechanism in the department of cardiology of the Second Affiliated Hospital of Zhejiang Medical University were selected as research objects. The retrospective study was conducted to investigate the relationship between PSVT with different types of reentry and basic heart disease, age and gender Relations, and analyze the differences between the various types. Results There was no organic structural heart disease in AVNRT and AVRT (66 cases and 91 cases, P> 0.05). IART and SNRT were more common in organic heart disease (7 cases each, P> 0.05) (65.8%), AVRT was more common in non-elderly men (46.4%), IART and SNRT were mostly in older men (P <0.01), AVNRT was more common in non-elderly women Accounting for 40.0% and 44.4%). Conclusion PSVT has different types of reentry due to different mechanisms of reentry, and there are some differences in PSVT between basic types of heart disease, age and gender.
