摘　　要：目的:探讨短阵房性心动过速的临床意义。方法:对65例短阵房性心动过速的动态心电图进行分析,其中45例有器质性心脏病(Ⅰ组),20例无器质性心脏病(Ⅱ组)。结果:短阵房性心动过速的检出率随年龄而增加,Ⅰ组年龄高于Ⅱ组(P<0.01),在Ⅰ组中房性心动过速的偶联间期长于房性期前收缩的最短偶联,短阵房性心动过速频率较快,发作前的窦性频率也较Ⅱ组快(P<0.05),且伴房室传导阻滞,窦房结功能及ST段压低改变。结论:动态心电图对短阵房性心动过速的临床诊断及预后有一定的临床价值。Objective:To explore the clinical importance of transient atrial tachycardia.Method:The dynamic electrocardiogram(DECG) of transient atria tachycardia was analysed in sixty-five cases.We divided sitxty-five cases into two groups.Forty-five patients have organic heart disease (group Ⅰ),twenty-five patients haven't obvious organic heart disease(group Ⅱ).Result:The ratio of transient atrial tachycardia increased with patient's age.The patient's age in the group one is higher than group two(P<0.01).In the group one,the coupling interval of atrial tachycardia is longer than the shortest coupling of atrial extrasystole.The frequency of transient atrial tachycardia and sinus rhythm is quicker than group two(P<0.05).The process follow with atrioventricular conduction block,sinus node and changing of S-Tsegment.Conclusion:DECG have certainly clinical value for the clinical diagnosis and prognosis of transient atrial tachycardia.
