纵膈腔占位致阵发性室上性心动过速3例

Mediastinal mass associated with Paroxysmal supraventricular tachycardia

目的总结纵膈腔占位伴发阵发性室上性心动过速（PSVT）频发病例的临床特点,探讨纵膈占位诱发PSVT的可能机制。方法对2010年10月~2014年4月我院收治的纵膈腔占位后出现PSVT频发的3例患者临床特点进行总结分析。结果 3例患者既往均无明确的心血管病及PSVT发作史,均于明确的纵膈腔占位确诊后出现PSVT现象,且随病情进展逐渐频发。结论提示两者存在因果关系,应引起临床重视。

Objective To summarise the clinical features of mediastinal mass complicated with paroxysmal supraventricular tachycardia（PSVT） and to investigate its possible mechanism. Methods The clinical features of mediastinal mass complicated with PSVT were analyzed in 3 cases admitted from Oct. 2010 to Apr. 2014 in our hospital. Results All of the 3 cases had no history of heart diseases or PSVT, and all suffered from PSVT after the definite diagnosis of mediastinal mass,Which occurred frequently With the progress of illness. Conclusions It suggests that there is a causal connection between PSVT and mediastinal mass, which should require much more attention.
